Brooks-Range Drift 15 Down Sleeping Bag: Lightweight, Water-Resistant
The insulation in the Brooks Range Drift 15 sleeping bag is treated with DownTek, a down coating that prevents the feathers from absorbing water. Since water rolls off the down, the feathers stay light and fluffy–keeping you warm. Unlike synthetic sleeping bags, which are typically bulkier and heavier than down, treated down sleeping bags offer the lightweight, low bulk warmth found in down bags without sacrificing packability.
