If you've ever watched Shark Tank, you might remember the pitch: clothing that keeps you warm even when you are soaking wet. That promise is what put Fortress Clothing on the map. As we head into the depths of winter (and the Ground Hog Day sales), the need for reliable gear in the outdoor Apparel industry is paramount.
We recently tested their patented AERIS® insulation technology. The claim? A 1-to-2 layer system that replaces bulky parkas. Today, we are breaking down whether the "warm when wet" hype is real, and handing you an exclusive Fortress Clothing coupon code that beats their standard site sale by an extra 3%.
The Good
- ✅ Warm When Wet: Retains heat even if submerged.
- ✅ Made in USA: Proprietary AERIS® insulation.
- ✅ Less Bulk: Replaces 4-5 traditional layers.
- ✅ Extreme Range: Rated from -35°F to 65°F.
The Bad
- ❌ Price: Premium investment (offset by coupons).
- ❌ Utilitarian Style: Focus is function over fashion.
- ❌ Sizing: Requires careful check of size charts.
Hands-On Review: Is AERIS® Legit?
We tested the BasePro 1/4 Zip and the Polar Puff Jacket. The first thing you notice is the weight—or lack thereof. It feels deceptively light for gear rated for sub-zero temperatures.
The "Wet" Test: This is the brand's core claim. AERIS insulation does not hold water like down, nor does it compress and lose loft like standard synthetics. In damp conditions (think freezing rain or sweat during high activity), the gear continued to trap body heat effectively. For outdoor workers or winter sports enthusiasts who sweat while moving, this is a game-changer because staying dry is usually the only way to stay warm. Fortress removes that constraint.

Expert Verdict
The Ground Hog Day sale offers a solid 18% off, but our exclusive code pushes that savings to 21%. For anyone working outdoors, skiing, or living in severe winter climates, Fortress Clothing is a high-value investment. The ability to eliminate multiple layers while maintaining warmth—even if you get wet—justifies the price tag. With the extra discount, it's a "Buy" rating from us.
