Sea To Summit - Trek TK II

Incorporating a 2D PermaShell™ fabric and a premium 650 loft down, the 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 sidewall, 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 traveling. The soft touch lining fabric is down proof by construction and highly breathable offering a comfortable sleep. The Trek series is Sea to Summit's choice for adventure travel and globe-trotting. Whether you are sleeping in hostels throughout Europe, backpacking in South America or discovering the Stirling Ranges in Western Australia. The tapered rectangular design offers a good compromise between the comfort of a generous cut shape and the 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.

Questions & Answers

I read that a "right" zippered bag means that, while in the bag on your back, the zipper will be on your right. The opposite of when looking at the bag from the outside. Is this correct?
