Product Description:

The Side Hustle WhatVest is ideal for carrying the essentials for a day on the mountain and designed for those who like to travel light. Made to be worn over your winter shell, this utility vest allows you to get on and off the chairlift with ease-- no need to take off a bulky backpack every time you get on the lift. Nine pockets total help distribute your gear evenly including four front outer pockets to store your keys, cell phone, radio, buffs, etc... and two inside front mesh pockets that are ideal for storing snacks, flasks, gloves etc... The low profile back zipper pocket provides space for extra layers, backcountry gear (shovel and probe) and is hydration pack compatible. The lower rear lumbar pocket is accessible while the vest is on with two-way access, providing another great storage area for gloves, goggle lens' or a water pouch. Side mesh panels and a front "air-out" clip help you stay cool when traversing or hiking to and from the goods. The WhatVest is designed to pack your essentials for a day on the hill without the bulk of a backpack. Sizing is based on the shell you would normally purchase, i.e. if you wear a large jacket, buy a large vest. We highly recommend viewing our new Sizing Chart for more details.
