Flash Down Pants – Ultralight Down Pants for Cold Weather Camping

The Flash Down Pants are ultralight down pants for cold weather camping and alpine missions where every ounce counts. Weighing just 180g (6.3 oz) and compressing to the size of half a water bottle, they deliver serious warmth with minimal bulk — perfect for cold camps, winter backpacking, or high-altitude overnights.

Insulated with 850+ fill power ethically sourced goose down, the Flash Pants offer warmth that rivals heavy fleece or synthetic layers at a fraction of the weight. The ultralight ripstop nylon shell is both wind-resistant and highly packable, designed to disappear into your pack until needed.

Thoughtful features include an adjustable waist belt for dialing in fit, reinforced seat fabric for durability while sitting around camp, and elastic ankle closures to seal in heat. For added versatility, they can be easily layered under a shell pant to create a full cold-weather sleep or travel system.

Whether you’re melting snow at basecamp, glassing from a windy ridge, or just trying to stay warm in your sleep system, the Flash Down Pants are a must-have for ultralight warmth on any winter-ready kit list.
