Details

Ultralight, protective, and roomy.

Sea to Summit's multi-disciplined 25 Degree Down Latitude Lt I Sleeping Bag is comfy for camping and light for backpacking above treeline. This ultralight bag uses lofty, compressible down insulation for a phenomenal warmth-to-weight ratio that's great for shoulder season camping trips or summers in the alpine. Sea to Summit treated the down insulation to resist moisture, retain loft, and remain warm in humid, moist conditions. The Nano Shell is water-resistant and windproof for extra weather protection when you're forced to spend the night high on the mountain.

The actual shape of the Latitude Lt I sits between mummy and rectangular designs, with a tapered profile that balances between the weight-savings of a mummy bag and the wiggle room of a traditional rectangular shape. Its adjustable hood and oversized draft collar block cold temps, and the bag's full-length zipper wraps around the anatomic footbox to convert the bag into a blanket during warmer nights. Sea to Summit finished this sleeping bag with an internal security pocket and included stuff and storage sacks for extra convenience.

Warm, and Tiny!

  • Familiarity: I've used it once or twice and have initial impressions

I was using this bag on a camping trip to mountain bike in Fruita, and honestly I couldn't be happier! Its packs down really small, is super warm, and its draft tube was amazing for when I got super warm in the middle of the night. The only complaint I may have is that the material seems a bit thin, but as long as you take care of it I don't see much of a problem. I think this would be a great bag for backpacking and getting outside!

For the space-conscious

  • Familiarity: I've used it several times

I recently completed a 300+ mile self-supported cycling tour and required a lightweight and packable shoulder season sleeping bag. I had used numerous other Sea to Summit packing solutions, but never a sleeping bag. After multiple nights, I can say the Latitude was almost perfect. Used in concert with their compression dry sack, I was able to minimize the space needed to carry the bag on my bike. I found the upper comfort range at around 50 degrees in dry desert conditions with a silk liner. All in all, this bag is a great value for those not 100% committed to minimizing weight & bulk.

Amazing Bag

  • Familiarity: I've used it once or twice and have initial impressions

This bag has been such an awesome purchase so far. It compacts down to about half the size of a loaf of bread and yet so far has kept me really toasty at night. I have an old sleeping pad that sometimes deflates on me but it still manages to keep the parts of me warm that are touching the ground. I think the material though is the definitely the best part! It feels like you're sleeping in hotel-like silk sheets. Bag liners are always helpful but with this bag, I don't even want to use one because the material feels so good! All around an excellent bag and I'm stoked to take it on more trips!!

Couldn't be more stoked so far

  • Familiarity: I've used it once or twice and have initial impressions

So far I couldn't be happier with this bag. It is amazing to have a little extra room for my feet. I supplement with a liner to keep the bag cleaner and it keeps me toasty. Packs down very well with the compression sack that is provided. Will update review once I've worn it out a little.
