Warm Enough for Spring, Fall, and Winter Nights

Cheap sleeping bags let the cold creep in through thin fabric, turning cool-season trips into a shivering all-nighter. This sleeping bag solves it with a silk-cotton fill wrapped in a soft flannel lining, built to trap body heat instead of letting it escape through a flimsy shell. The envelope-style design gives you room to shift through the night instead of feeling cinched into a mummy bag, and a built-in pillow means you're not stuffing a jacket under your head at 2 a.m. This bag makes cool-season nights feel like summer ones.

Waterproof Outer Shell Built to Handle Wet Conditions

The outer shell is a polyester-cotton waterproof fabric, chosen to keep rain and condensation from soaking through to the insulation, while the fill itself uses two layers of 200 gsm silk cotton for real cold-weather warmth. Inside, a cotton flannel liner sits against your skin, soft enough to sleep in without a separate sheet. It's built in an envelope style that unzips fully for airing out or spreads open like a blanket on warmer nights, and it comes in a standard 200 x 90 cm size or a lengthened 200 x 120 cm version for taller sleepers. At around 5 kg, it's substantial enough to hold real warmth without being unreasonable to pack, and the whole thing is fully washable after a muddy trip.
