We have 3- and 4-season sleeping bags for alpinism, mountaineering, trekking, backpacking, and camping. We sub-categorise our range into down and synthetic. If you're unsure, here's a tip: choose down if you're sleeping in dry conditions and want the best breathability and packability possible, choose synthetic if you need a warm-when-wet sleeping bag for extreme conditions. We also stock sleeping bag liners to add warmth and keep your sleeping bag cleaner.
