I love my sea to summit trek i - Sea to Summit Trek Tk I Sleeping Bag -650 Down-

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 sewn into the top of the sleeping bag on the inside to stash personal effects such as a watch, headlamp, wallet, etc.
