Our reviewer used the Montbell Tachyon nearly every day of their hikes on The Pacific Crest Trail, Continental Divide Trail, Vermont Long Trail, and other shorter backpacking trips. Its light weight, packability, and backpacking-specific design make the Montbell Tachyon the best windbreaker for hiking and longer backpacking trips.
The Tachyon’s thin fabric and simple design keep the bulk down, and it is an excellent piece for cool day hikes; for breaks on mild days; for summiting a chilly, windy peak; or hiking in before and after sunrise during your more ambitious days out. Where we found the jacket to shine is on multi-day backpacking trips—no matter the climate. It keeps the warmth while hiking when the wind makes an otherwise mild weather day. You'll find it listed as an ultralight backpacking favorite gear item in our guides to the Appalachian Trail, Pacific Crest Trail, Continental Divide Trail, and John Muir Trail as well as our Bikepacking gear list.
