Summer camping and overseas trekking.

Your trekking partner's unwieldy synthetic sleeping bag fills his entire backpack. Your Sea To Summit TkI Down Sleeping Bag compresses into the bottom corner of your pack and leaves room for extra shirts, shorts, skivvies and, oh, you know, a stove and stuff like that. This 32-degree bag keeps you company during summer camping trips and travels.
  • A lower limit rating of 32F and a comfort rating at 41F mean this bag is best suited to summer use or shoulder-season trips in milder climates
  • 650 Fill power down for a sweet warmth-to-weight ratio (warm and lightweight)
  • Nylon shell features DWR treatment to repel moisture and stains
  • Unzip the full-length zipper and use this bag as a duvet at hostels or on mid-summer desert trips
  • Foot zip lets things air out when the sun starts to rise
  • Large internal pocket stores skivvies or wallet
  • Differential-cut shell and lining allows the down to loft fully both on top and bottom
  • Anti-snag zipper system uses a high-density poly cloth hidden in the draft tube so the zipper won't stick
  • Can be zipped together with other Sea To Summit bags (Trek, Traverse, and Alpine) to create a double bag

How's the sizing on this thing? I've heard that they may run a bit small and people close to 6' need to get the long.

I have a long in the 12 degree version, and a regular in this. I am 5'11"
and the regular is about perfect.

Cool Bag, but not at 32 degrees

I bought this bag because it is lightweight, packs small, rated to 32 degrees and it zips out fully so you can use it as a blanket. So far, its been a great bag but I think the real rating is more like 40 degrees. Trust me, I'm a warm sleeper anyway. Not a deal killer for me because I'll still get a lot of use out of it, but wanted to let anyone else know.

This is more meant for a summer bag anyway. The comfort rating is 41 degrees and I feel it is true to that rating.

Can you give me approximate pack size

Hi John,

STS gives their stuffed sizes for their new bags based on liters, and their bags come with compression sacks. The Trek I comes with a size small sack which goes from 10L- 3.3L. Uncompressed, that translates to 7x16". Fully compressed, that's going to give you about 7x5-6".
