Product Info for Sea to Summit Trek Tk I Sleeping Bag -650 Down-

With its tapered rectangular cut, there is plenty of room to move if you happen to be a wriggler. The side and foot box zippers offer excellent ventilation and may be unzipped completely to provide a blanket or quilt style system.

Underspec'd and overdelivers

by captain camptastic, from VA, United States Updated on August 1, 2019

These bags are advertised as >650 down and the test results included with the bag showed substantially greater fill power. I'm a cold sleeper and the TKi kept me toasty on a high 30s overnight trip. Really great loft, light weight, and spacious. Great 2-3 season bag.

Roomy for a good nights rest

by JoeA, Updated on August 1, 2019

I love my Sea to Summit Trek I

by David T., Verified Owner from TX, United States Updated on December 14, 2016

This sleeping bag is manufactured well and looks good. It compresses down well with the included compression sack. It is rated to 32 degrees F which is enough for me. There is a Trek II and III if you require more warmth. The sleeping bag has a snag free full length zipper. A second zipper unzips the foot box to use the sleeping bag as a comforter/duvet. There is a compartment ...
