10 Best Base Layers For Hunting 2025 in the United States

The Under Armour Men's ColdGear Armour Fitted Mock is designed with dual-layer fabric that features an ultra-warm, brushed interior and a smooth, fast-drying exterior. This makes it highly effective in cold conditions, perfect for hunting activities. The mock neck construction adds extra coverage and warmth, which is essential during colder hunts. The stretch-mesh back and underarm panels provide strategic ventilation, ensuring you stay warm without overheating.

Its 4-way stretch construction allows for better mobility in every direction, which is crucial for comfort while moving in the field. The material is excellent at wicking sweat and drying quickly, helping to keep you dry during intense activities. Additionally, it features an ergonomic design that keeps seams off high abrasion areas, enhancing comfort and reducing chafing.

The fitted design offers a streamlined fit that's neither too tight nor too loose, making it ideal for layering under other clothing. The durability of the material appears strong, though real-world usage will truly test its resilience over time. This base layer is suitable for hunters looking for warmth, comfort, and mobility.

The Merino.tech Merino Wool Base Layer Set is a strong contender for those in need of a reliable base layer for hunting. Made from 100% superfine 17.5-micron merino wool, this set is designed to provide all-day comfort without the itch often associated with wool. The midweight option at 250 g/m² strikes a balance between warmth and breathability, making it suitable for a range of temperatures.

One standout feature is its natural moisture-wicking and odor-resistant properties, which ensure you stay dry and fresh during long hunting trips. Additionally, the set comes with a pair of merino wool hiking socks, adding extra value to the package. On the downside, the care instructions recommend hand washing and air drying to maintain durability, which might be less convenient for some users.

Despite this, the Merino.tech Promise offers peace of mind with a satisfaction guarantee. This base layer set is a solid choice for hunters looking for comfort, moisture management, and odor control in their thermal wear.

The SITKA Gear Men's Core Lightweight Hunting Hoody offers several features suited for hunters. Made from a lightweight, quick-drying knit material, this hoody effectively wicks moisture away from the skin, ensuring comfort during different activity levels. The built-in mesh face mask provides quick concealment and doubles as a neck gaiter, offering protection against insects like mosquitoes.

The drop-tail design helps to keep the hoody in place and adds extra coverage, which is beneficial for sun and moisture protection. It also features stretch thumb loops that make it easy to add or shed layers without the sleeves bunching up, and a convenient chest pocket with a YKK zipper for secure storage of small items. The half-length front zipper and offset shoulder seams add to the comfort and functionality of the garment.

Incorporating Polygiene technology, the hoody neutralizes odors caused by sweat, making it an excellent option for staying fresh in the field. While the product might be considered a bit pricey for some, and the lightweight material may not offer the same level of durability as heavier, more robust options, the fit described as 2X-Large should be checked carefully to ensure it meets individual sizing needs.
