At just 455 grams (size L), the Altitude Ultralight Puffer is our most lightweight puffer jacket yet, delivering impressive warmth without the bulk.

It’s engineered for wearing on-the-go, whether you’re hiking, climbing, mountain biking, or commuting to work during the cooler months. It’s also a great option for the hut, campsite, or outdoor gatherings.

The jacket has 140 grams of 700 loft, RDS duck down (50%) and Sorona® Aura insulation (50%), a partially plant-based fibre that’s warm, breathable, and lightweight. Duck down provides excellent warmth while Sorona® maintains the integrity of the down, preventing it from collapsing or clustering even when wet. The zoned baffle system ensures insulation is distributed evenly for optimal thermal performance.

The ultralight micro ripstop nylon face fabric is treated with DWR for water repellency so you can wear it during light showers. For heavier downpours, the Altitude is light and compact enough to wear under a rain jacket.

The jacket’s equipped with abrasion-resistant cuffs and shoulder patches to provide extra water resistance and durability in high-wear areas.

It has a dual-way zip and two domes on the front, which allow you to offload heat when you’re on the move. There’s a gusset zip, which allows the collar to expand to accommodate a climbing, mountaineering, or abseiling helmet. The adjustable hood can also be domed down when not in use.

The Altitude is a packable puffer jacket, meaning it packs into its own side pocket. The convenient, compact size is ideal for carrying in a hiking pack or day bag.

The Altitude Ultralight Puffer Jacket pushes the boundaries of lightweight warmth and performance, keeping you toasty on the trail, around town, and everywhere in between.
