When it comes to hunting, keeping your feet warm and dry is essential for maintaining your comfort and focus in the field. Insulation plays a key role in this, as it helps to trap heat and prevent heat loss in cold environments. There are several types of insulation to choose from, each with its own benefits and drawbacks. In this article, we will discuss the different types of insulation used in hunting boots and provide some considerations for choosing the right insulation for your needs. We will also highlight some top picks for hunting boots with gram insulation and provide tips for caring for and maintaining your boots to ensure that they stay in good condition for seasons to come.
Types of insulation
Thinsulate is a synthetic insulation material that is known for its warmth, lightweight, and breathability. It is made from microfibers that trap body heat and provide warmth without adding significant weight or bulk. Because it is highly breathable, Thinsulate helps to keep feet dry by allowing moisture vapor to escape from the inside of the boots. This makes it a popular choice for hunting boots, as it can help to keep feet warm and comfortable in cold weather conditions.
Gore-Tex is a waterproof, breathable membrane that is widely used in outdoor gear, including hunting boots. It is made of millions of microscopic pores that are too small for water to pass through, but large enough to allow moisture vapor to escape. This helps to keep feet dry by preventing sweat from building up inside the boots, which can cause discomfort. Gore-Tex is a popular choice for hunting boots because it provides excellent water resistance and breathability, helping to keep feet dry and comfortable in wet conditions.
Primaloft is a synthetic insulation material that is known for its warmth, lightweight, and compressibility. It is made from ultrafine fibers that mimic the properties of natural down, yet are water-resistant and able to maintain their insulating properties even when wet. This makes it a popular choice for hunting boots as an alternative to down, as it offers similar warmth and loft, but is more resistant to moisture. Primaloft is also highly compressible, which makes it a good choice for hunting boots that need to be lightweight and packable.
Thermolite, Hollofil, and Microloft
There are many other synthetic insulation materials that are used in hunting boots, such as Thermolite, Hollofil, and Microloft. These materials are typically made from synthetic fibers that are designed to provide warmth, lightweight, and water resistance. They may be less expensive than other options, such as Thinsulate or Primaloft, but may not offer the same level of warmth or moisture management. It’s important to consider the specific features and performance of each insulation material to determine which one is the best fit for your needs and preferences.
Considerations for choosing insulation
Temperature range and activity level:
The amount of insulation you need in your hunting boots will depend on the temperature range and activity level you will be experiencing while hunting. If you will be hunting in very cold temperatures and will be relatively inactive, you may need more insulation to keep your feet warm. This is because your body heat will not be generating as much warmth, so you will need the insulation to help trap and retain heat. On the other hand, if you will be hunting in milder temperatures or will be more active, you may not need as much insulation, as your body heat and activity level will help to keep your feet warm. In this case, you may prefer a lighter weight or less bulky insulation material, as it will not be as necessary for warmth and may not be as comfortable in warmer conditions.
Weight and bulk of insulation:
Insulation can add weight and bulk to your hunting boots, which is something to consider if you need to carry your boots for long distances or if you prefer a lighter weight boot. Thinsulate and Primaloft are generally lighter and more compressible than other insulation materials, which makes them a good choice for hunting boots that need to be lightweight and packable. However, it’s important to find the right balance between warmth, weight, and packability, as too little insulation may not provide enough warmth in cold temperatures, while too much insulation may be too heavy and bulky.
Water resistance and breathability:
It’s important to find an insulation material that provides good water resistance and breathability to keep your feet dry and comfortable while hunting. Gore-Tex is a popular choice for this purpose, as it is a waterproof, breathable membrane that is effective at keeping water out while still allowing moisture vapor to escape. Synthetic insulation materials may also offer some water resistance, but they may not be as effective at keeping feet dry as Gore-Tex or other waterproof, breathable membranes. It’s important to consider the level of water resistance and breathability that you need when selecting insulation for your hunting boots, as this will help to ensure that your feet stay dry and comfortable in wet conditions.
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.
