Hybrid Hoodie - Fortress ClothingEMPLOYEE'S GO TO

Hybrid Hoodie

Recommended by Mike L
“The best do-it-all jacket in my closet. It fits great and handles work, everyday wear, snow, and rain. It’s my go-to anytime the temperature drops below 50°F, and it keeps me warm down to around -15°F. I love the green color. My fit: 6'2", 230 lbs — I wear a 2XL. I recommend sizing up for the best fit.”

Polar Puff

Recommended by Dale CEO
“Lightweight warmth without the bulk. The Polar Puff is one of my go-to jackets when the temperature drops. It’s comfortable, easy to move in, and great for everything from everyday wear to outdoor adventures in cold weather. My fit: 6'3", 210 lbs — I wear an XL. I recommend sizing up if you want a little more room for layering.”

Ultra-Light Vest

Recommended by Devan W
“One of the most underrated products we make. This vest is incredibly versatile and adds a ton of warmth without the bulk. Layer it over BasePro, a hoodie, or even a long-sleeve shirt. You can also wear it under your favorite jacket when you need extra warmth. It’s perfect for colder climates when you need another layer, or warmer climates when a hoodie and vest are all you need. Honestly, one of my favorite Fortress products ever.”
