What Gram Insulation For Hunting Boots?

When buying a pair of hunting boots, it is important to consider the insulation level. It is possible to overheat in boots with too much insulation, and the odor from sweat can scare away the game. Hunting boots are available with four different types of insulation, and each has its advantages and disadvantages.

What Gram Insulation For Hunting Boots?

1. Thinsulate


When you are shopping for insulated hunting boots, you may want to look for Thinsulate. This type of insulation is lightweight but provides superior warmth. It’s not waterproof, but it will keep your feet dry and warm, especially in cold weather. This material also has the advantage of being washable. Most other types of insulation are dry-cleaned only.

This material is made of lightweight synthetic fibers that have a thermoplastic coating and can help keep your feet warm in extremely cold temperatures. Thinsulate is available in various weights, but it’s best to choose one that’s between two hundred grams. Its high insulation value makes it an excellent choice for hunting in cold climates.

You should also choose a pair of socks with Thinsulate insulation. A good pair of hunting socks will keep your feet warm when it’s dry and warm when they’re wet. This is especially important if you’re wearing a waterproof pair of boots. Merino wool socks will also help keep your feet dry.

Depending on how active you are, you may want a pair of boots that are lightweight and breathable. If you’ll be working outside, you may want to consider a pair without Thinsulate lining. These types of boots will keep your feet from overheating in cold weather.

The amount of Thinsulate insulation in hunting boots varies. Some have as little as 200 grams of insulation, while others have up to four hundred. For moderate activities, you should look for hunting boots with 400-600 grams of insulation.

2. Shearling vs. Thinsulate

Shearling boots

When it comes to the insulation in your hunting boot, there are many options. You can get a pair lined with Thinsulate or go for something warmer like Shearling. You also have the option of choosing between a waterproof or breathable material. You might want to consider purchasing a waterproof, breathable option, which will keep your feet warm during a harsh cold spell.

Shearling is made from soft, fluffy fleece. It is produced naturally or artificially. It is very comfortable and provides extra insulation, but is not suitable for extreme cold or extreme heat. The sheepskin lining is another option, as it is soft and moisture-wicking. It also provides an extra cushion in the shoe. Another option is made from synthetic materials, such as Sherpa. Sherpa mimics the texture of shearling but is easier to clean.

Thinsulate is the most common synthetic insulation in hunting boots, but it is not the only choice. There are many other options, including Primaloft, HeatSeeker, and Zylet. Shearling is a fine fleece that makes your boots warmer but is designed for everyday wear and low-activity environments.

Thinsulate is the more durable option. This type of insulation can handle more rugged activities than Shearling. Thinsulate boots come in various weight insulation levels, from 400g to 800g. If you’re looking for a lighter-weight option, consider buying a pair of Thinsulate boots.

While both materials can keep your feet warm, the insulation level is important. The higher the number, the warmer it is. For winter activities, however, you’ll need to wear waterproof boots. You can look for Gore-Tex-compatible waterproofing in your hunting boots.

What does “Grams” mean in hunting boots?

The gram of insulation in a pair of hunting boots is a number between zero and one thousand. A pair that has zero grams of insulation is not insulated, and a pair with 400 grams of insulation will remain warmer despite the weather outside. The higher the grams, the warmer the boot will be, and it will also be lighter. You can supplement with a warm pair of socks if you need to.

When purchasing a pair of hunting boots, make sure to check the grams of insulation and the thickness of the leather. A thicker boot will be more durable. One type of insulation is 3M(TM) Thinsulate, which is thin and light. It will keep your feet dry and warm even in wet conditions and will keep your feet warm during a long walk.

There are many different ways to determine how much insulation you need in your hunting boots. For moderately cool days, you can opt for a boot with less insulation. For colder weather and moderate activity, you can opt for one with one hundred to eight hundred grams of insulation. Another category of hunting boots has a thousand grams of insulation.

Insulation in a hunting boot is important for keeping feet warm. An insulation rating of one hundred or more grams is perfect if you’re hunting in relatively warm weather, while a boot with a lower insulation rating will keep you warm in extreme cold. It is also important to remember that the weight of insulation in a boot is affected by the type of socks worn with it, and the level of activity.

In addition to insulation, hunting boots must be comfortable and durable. They should be made from leather with double or triple stitching for increased durability. You should also look for the lining of the boot.

A good pair of hunting boots should weigh between 600 grams and 800 grams, and a midweight pair should weigh between 1,200 grams and 1,600 grams. It is also important to consider the material of the boots. Generally, field boots are made of mesh or nylon to help keep moisture out and keep the boot breathable.

On the other hand, rubber hunting boots are waterproof and scent-free, but they can be quite warm. Depending on the time of year, the amount of insulation in your hunting boots will be different, so it’s important to decide how warm you want your boots to be. For example, in early-season hunting, you may want 200 grams of insulation, while in the fall and winter you might need 400 to 800 grams of insulation.

200g vs. 400g

When choosing hunting boots, you will need to think about the insulation. A boot with 200 grams of insulation won’t keep your feet too warm in the summer, and a boot with 400 grams of insulation will keep your feet warm even in the coldest winter weather. In addition to insulating your feet, hunting boots should be comfortable and prevent your feet from getting blisters or cuts. Although insulated boots are not designed to be breathable, newer designs in the footwear industry offer better breathability.

While 200g of insulation is enough for colder weather, a boot with 400 grams of insulation is best for moderate climates and moderate activity levels. It will keep your feet warm even if you’re active for several hours a day. In warmer climates, a 400g boot will keep your feet warm and protected but won’t keep you as comfortable.

As a general rule, 400g boots are the best choice for mild temperatures, keeping your feet warm in temperatures as low as 30degF. If you’re a hunter who enjoys light activity in cold weather, you may want to opt for a 400g boot.

A 400g boot will have four hundred grams of Thinsulate insulating material. That’s about 1.5 pounds more than a 200g boot. The insulation is also smaller – two hundred grams of Thinsulate can cover an area of over 10 square feet.

Depending on where you’ll be hunting, you may want to choose hunting boots with a higher insulation level than a 400g one. You may also want to consider the weight of the boot. If you’re walking in town, 200g of insulation is enough. If you’re in a cold climate or need to remain still for extended periods of time, 400g of insulation can be a good choice.

400g Vs. 800g Thinsulate Boots

You might be wondering: what is 400g Thinsulate and what is 800g Thinsulate? These two types of insulation to keep your feet warm during temperatures below 30degF and 40degF, respectively. However, these two types of insulation should only be worn if you plan to do light activity in them.

What is 400-gram Thinsulate?

The term “Thinsulate” is used to describe the thickness of the insulation. The grams of Thinsulate in a boot do not refer to the weight of the entire boot, but rather the amount of Thinsulate per square meter. So a 400g boot has approximately 400 square meters of Thinsulate and will be lighter than an 800g boot. A boot with 400g of Thinsulate will still provide protection against cold weather, even if the wearer is doing light activity.

What is 800-gram Thinsulate?

Thinsulate is an excellent material for keeping warm. It’s made from fine microfibers that trap warm air molecules. These fibers also allow moisture to evaporate. If you live in a cold climate, 800 grams of Thinsulate will provide plenty of protection. Depending on the temperature in your area, you may even need a higher level of insulation.

An 800-gram Thinsulate boot may seem bulky and heavy, but it’s actually a good choice in very cold temperatures. This type of insulation makes your feet warm, while still offering great grip and insulation. It’s also slip-resistant, so it’s good for rough terrain.

This insulation can protect you from frostbite in very cold temperatures, as it resists water. It also keeps your feet from sweating while you walk on snow.

When choosing 400-gram Thinsulate?

There are two basic types of winter boots. One is waterproof and the other is insulated. Waterproof boots are more effective at keeping your feet warm than insulated boots, which are not always the best choice for cold weather. Both types of winter boots have their advantages and disadvantages. Waterproof boots are ideal for wet or warm winter weather but are not recommended for athletic activities.

It’s best to stay away from boots with more than 400 grams of Thinsulate because they will be much heavier and limit your mobility. Also, they won’t be as effective if you are working in a workplace where temperatures can dip below freezing. However, for light activities, 400 grams of Thinsulate boots are more than adequate.

There are two types of Thinsulate boots: 800 G and 400 G. The former is designed for everyday wear, while the latter is better for rugged uses. The latter is a more expensive option for those who are constantly outside in colder weather. These types of boots are designed to protect your feet from rain or snow and have durable synthetic insulation.

When choosing 800-gram Thinsulate?

800g Thinsulate boots are extremely warm, but they are also heavy. You might want to consider other options if you want your feet to remain warm, such as lightweight hiking shoes. But you may also find that a heavy-duty pair of boots can limit your range of motion. And if you do not want to spend a lot of money, you can always consider 400g Thinsulate boots. They are a practical choice if you plan to do light hiking or camping in the snow.

For the most part, 800 G Thinsulate boots are sufficient for the winter. They will keep your feet warm enough in temperatures from 30 to 40 degrees Fahrenheit. But if you plan to work outdoors or do other activities where your feet will get wet, then you will need something warmer.

The most common materials for insulating boots are Thinsulate and shearling. Thinsulate offers excellent insulation, and it is durable and won’t break down easily. Shearling, on the other hand, is more snuggly and warm. It traps air molecules inside the microfiber and keeps your feet warm in cold weather.

How much Thinsulate do I need in hunting boots?

When choosing a pair of insulated boots, the weight and thickness of the insulation are important factors. Although grams of Thinsulate represent the thickness of the insulation, they don’t necessarily reflect the overall weight of the boot. A boot with 400 grams of Thinsulate will weigh less than one that is 800g. This difference in weight and thickness can impact the boot’s temperature rating.

Insulated boots come with different weights of insulation. Depending on the insulation weights the boots may be better for mild to freezing temperatures. Here are the insulation weights you’ll find when shopping for boots:

  • 200 grams: Works best for cool temperatures and little to no activity, or for high activity levels in cold weather.
  • 400 grams: Works best for cold temperatures when doing the moderate activity.
  • 600 grams: Works best for colder weather conditions and low activity levels.
  • 800 grams: Works best for very cold weather and low activity.
  • 1,000+ grams: Works best for extremely cold weather conditions with very little activity.

If your boots are Uninsulated then:

  • Fist bump down to 8mm (3/8 inch) of insulation – Maximum weight 5 ounces / 140 grams for the pair if the boots are size 10 or smaller.
  • Fist bump down to 12mm (1/2 inch) of insulation – Max weight 6ounces / 170 grams for the pair if the boots are size 11 or smaller.
  • Fist bump down to 16mm (5/8 inch) insulation – Maximum weight 8 ounces / 220 grams for the pair if the boot is size 12 or smaller.
  • Fist bump down to 20mm (3/4 inch) insulation – Maximum weight 9.5 ounces / 270 grams for the pair if the boots are size 13 or smaller.

If your boots are Insulated already:

  • Fist bump up to 12mm (1/2 inch) of insulation – Maximum weight 8 ounces / 220 grams for the pair if the boots are size 10 or smaller.
  • Fist bump up to 16mm (5/8 inch) insulation – Maximum weight 9.5 ounces / 270 grams for the pair if the boots are size 11 or smaller.
  • Fist bump up to 20mm (3/4 inch) insulation – Maximum weight 12 ounces / 350 grams for the pair if the boot is size 12 or smaller.
  • Fist bump up to 24mm (1 inch) insulation – Maximum weight 14 ounces / 400 grams for the pair if the boots are size 13 or smaller.


To find the perfect pair of insulated boots, you must know how much insulation you need. You should also keep in mind your activity level. This will help you decide which weight is right for your needs. Generally speaking, you should purchase a weight that is around 1000g, and less than half of that is enough for most people.
