Incorporating their 2D PermaShell fabric and a premium 650 loft down, Sea to Summit Trek bags are a refined classic. 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.
Built for those who like a little extra wiggle room but still want to stay cozy, the Sea to Summit Trek TkII features a semirectangular shape to give you the best of both worlds. This versatile sleeping bag is a great choice for everything from weekend backpacking trips to month-long globe-trotting excursions.
