Reviews

"Huge thank you to @whatvest for bringing my vision for a custom heli vest to life. The crafting and durability is top of the line and in addition to fitting my entire backcountry kit, it's equipped with both snowboard and ski carry capabilities and fits a large ICU for my camera equipment in its back compartment. If you can imagine it, Nadia can make it for you—hit them up."

"The WhatVest is awesome! It is my go to for long days charging on big mountains and great for side-country access when you need your avi gear. Badass, burly construction and materials; fantastic design with everything you need, right where you need it. The fact that they have a huge color palette only makes it that much better a product. Having worn vests by Dakine, Helly Hansen and North Face, I am confident in saying this is the best on the market. 10/10 would and do recommend."

"My custom ski patrol WhatVest is bomber. It handles all my everyday rescue gear with ease and keeps it tight. It has extra room for food and water for extended rescues as well. Can’t say enough about this vest. Durable, comfortable, well thought out features. Thanks again you guys, your gear rocks!"

— Kevin Brazel, Jackson Hole Ski Patrol
