Looking for a truly high-performance, technical, insulated vest? You found it. The Fusion 90 Vest is built from the same materials as our angler-favorite 3/2 Puffy Jacket. 90 grams of synthetic, spiral bound synthetic insulation trap heat, while an abrasion resistant, water repellent, 4-way stretch shell locks wind and weather out. An adjustable, insulated hood keeps your head and neck toasty. The Fusion 90 Vest is perfect for variable weather days when you want multiple layering options. Wear it as an outer layer for mild conditions or a core-furnace midlayer if the temperature turns bitter.

"Four stars because the vest is much longer than it needs to be. If you have a normal torso like I do, the large will hang down below the pockets on your jeans. Overall design is well thought out other than that. Phone pocket and zippers work slick."
"This vest is incredible!! It’s warm, it’s breathable, fits great! Wore it skiing for a week in Colorado and was the perfect piece to my kit. Can’t wait to use it on the river next week!!"
"This vest is an excellent layer. Fit is true to size. Not too much extra fabric. The hood seals the deal. Always!"
"I first saw the Fusion 90 vest at the 2026 Denver Fly Fishing show in February. I saw their new line of clothing and spoke with one of the representatives. He showed me the vest and I couldn't believe the feel of the material and the fine detail. I tried it on and the fit was amazing as well as the comfort of it. It fit so nice I purchased it right then and there. I've worn it quite a few times in some very chilly temps and it was just a great warm vest. I even wear it casually in the house too! This is by far the nicest vest with a hoody I've found for cool to cold weather, whether it be for fishing or just casual wear. Highly recommended!"
"Buy one now. You won’t regret it."
"Functional, comfortable and simply amazing! Can be used on the river or a night on the town!"
"I love swallow, and I have used every single fly fishing company all the big ones in my 50 years of fishing and you’re the best"
"Super warm, but a little big."
"Awesome vest"
