Sea to Summit Trek TkII 18ºF Ultra-Dry Down Sleeping Bag - Discontinued Model

Incorporating Sea to Summit's® 2D PermaShell™ fabric and a premium 650+ Loft ULTRA-DRY 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 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 traveling. 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.

Following a successful 1984 climb up the north face of Mount Everest, one of the summiteers, Tim Macartney-Snape decided to return six years later so that he could do what no one else had done - climb it starting from sea level, that is from "sea to summit".

For this trip, in 1990, Tim swam in India's Bay of Bengal and then set off on foot across the Gangetic plain toward the distant Himalayan foothills and four months later, set foot once again on the highest point on earth. Tim's solo ascent of Mt. Everest was named the "Sea to Summit" expedition.

Back in Australia, he joined forces with friend Roland Tyson to build a business that could make use of their knowledge of the outdoors to create truly ingenious, well-made but affordable outdoor equipment. They named their company Sea to Summit® after Tim's expedition and the business prospered. Today the Sea to Summit brand continues to provide innovative gear and serves a growing band of outdoor enthusiasts all over the world.
