When it comes to cold-weather clothing, traditional layering systems require multiple pieces to keep you warm, dry, and comfortable. But what if you could replace 2-4 layers with a single, high-performance system? Fortress Clothing™ has revolutionized baselayers with our USA-patented insulation technology, ensuring superior warmth, flexibility, and moisture management even when wet.

Why Fortress Base Layers Are a Game-Changer

1. Replaces Bulky Layers
   Traditional layering systems can be cumbersome and restrictive. With Fortress Base Layers, you get unmatched warmth without the bulk, simplifying your gear while improving mobility.

2. Stays Warm Even When Wet
   Unlike standard fabrics that lose insulation when damp, Fortress’s AERIS™ insulation retains heat in all conditions, keeping you warm and comfortable in rain, snow, or sweat-heavy activities.

3. Moisture-Wicking & Breathable
   Active in extreme cold? Fortress Base Layers are designed to wick away moisture, preventing overheating while keeping you dry and warm during high-output activities.

4. All-Day Comfort & Mobility
   Constructed with 4-way stretch materials, our baselayers move with you, offering flexibility for hiking, hunting, working outdoors, or any adventure in frigid temperatures.

5. Versatile Performance (-5°F to 60°F)
   Whether worn alone in mild temps or layered under other Fortress gear for subzero conditions, BasePro adapts to your environment, making it the ultimate all-season base layer.

Simplify Your Cold-Weather Gear
