Atmos is here to help manage your personal microclimate. This light and breathable jacket offers instant warmth when you need it, and packs away small when you don’t. The underarm vents, heat-trap cuffs and neck will make it a go-to for big mountain missions, but it’s just as effective as your daily driver.

The 700-fill Wool x Down composition balances two of nature’s finest insulators – with duck down for loft and merino wool to help manage moisture for outstanding climate control, you will be comfortable no matter what the conditions.

Atmos uses a light, soft touch 100% recycled Pertex® Quantum shell to allow the insulation to fully loft. A PFC-free durable water repellent (DWR C0) finish sheds light rain and snow to provide additional weather protection.
