The warmest bag in the Sea to Summit Trek range of sleeping bags, the Tk3 is a bag for those with a wider frame not wanting to resort to a more restrictive mummy shaped bag. Packing down to 5L, it’ll fit neatly in the bottom of most trekking packs.  

The bag incorporates highly-breathable 2D PermaShell™ fabric which will keep your down in tip top shape. The tapered rectangle design makes the Trek ideal for people with a larger frame or slickers for space. The full length side and foot zips mean you can zip it wide open and use it as a quilt, for those warm nights or if you have company. A two-dimensional hood is useful for trapping extra warmth on those colder nights.

An oversize internal pocket is big enough to keep your wallet, passport, and iGadget. The lightweight Ultra-Sil® compression bag compresses the bag down to a mere 7L. The Trek Tk1 is a bag for the trekker wanting a freer night sleep, but with the warmth to get them through a cold night in the hut.
