The Montbell Tachyon is a soft, lightweight windbreaker with sizeable hand pockets, making it a good option for hikers who want something durable, practical, and small enough to stuff away when not in use. In particular, I appreciated the soft fabric that didn’t “swish” as loudly or feel as cumbersome as the other jackets we tested.
At only 2.3 oz, I’d argue this also makes a good ultralight backpacking option, though slightly less weather resistant than the Black Diamond Distance Shell or the Patagonia Houdini Air. It’s a thin jacket that is excellent for breezy or mildly windy days but less ideal for high and chilly gusts. The packable jacket stuffs down into a pocket, has elastic cuffs, and is made from 7-denier Ballistic Airlight nylon ripstop—an ultra-lightweight, comfortable material—with a water-repellent finish.
