Sea to Summit Backpacking Sleeping Bags Trek Tk I Sleeping Bag (650 Down)-Regular-Left-Orange 041RWL. The 60/40 fill ratio in the Trek bags is maintained using a side block baffle and differential cut shell. In the top of the shell a 3D side wall a feature normally reserved for technical alpine sleeping bags provides more space for the down to loft right to the edge of the bag. An oversized security pocket located inside the bag is easily accessible ideal for stashing passports and other valuables while travelling. The soft touch lining fabric is down proof by construction and highly breathable offering a comfortable sleep. The tapered rectangular design offers a good compromise between the comfort of a generous cut shape and warmth of a closer fit. A full length side and foot zip allow the Trek series to be opened out into a full duvet for use indoors and warm weather.

You've always wondered why some of your backpacking buddies would choose to suffer in the frigid temperatures that inhabit autumn and spring. But you, you're different--you're more of a fair-weather backpacker, in that you choose to backpack when the weather is fair. That's why you opt for Sea to Summit's Trek TkI Sleeping Bag, a bright bundle of joy that's light on your back and warm throughout summer's standard temperatures. Despite being one of Sea to Summit's many minimalist-minded options for trekkers who'd rather have less weight than more features, the Trek TkI still stuns you with innovations like the Ultra-DryDown treatment which helps bag's down insulation retain its lofty warmth when you camp in moisture-riddled climates.
