Product description

A warm and comfortable down sleeping bag for backpacking and temps down to around freezing: the Trek TkII from Sea to Summit. Featuring a tough outer shell and water-repellent down insulation, this bag is ready to withstand moisture, be it from the inside or the outside. To prevent the down shifting and cold spots forming, Sea to Summit has used vertical chest baffles. The 3D side-wall baffle ensures that down can loft to the edge of the bag, thus maximising insulation and preventing you from freezing. The hood helps here as well and comes with a drawcord to cinch it around your face. If you get too hot, you can adjust the hood so that it lies flat and heat doesn’t build up. The bag also features a 2-way YKK zip for easy entry, ventilation and connecting it to another sleeping bag. The zip at the foot box allows you to convert it into a blanket as well, which is great for couples or when it gets a bit warmer out. As for storage, there is a practical inside pocket for batteries or valuables. A compression bag is included with the sleeping bag as well. With the Trek TkII, you’ll have everything you need and plenty of comfort to boot! A real all-rounder!
