A quilt for the minimalist adventurer.

Sea to Summit's Ember EB I Sleeping Bag is more of a quilt than a bag, and its zipperless design gives the ultralight, ultra-compressed convenience that minimalist backpackers, alpinists, and touring cyclists need. Ultra-Dry Down 750+ insulation gives this quilt a phenomenal weight-to-warmth ratio that only weighs around a pound and stays warm enough for summer trips.

Sea to Summit treated the Ember's down insulation to resist moisture, remain lofty, and retain its warmth in humid, moist conditions. The quilt's bottom has a drawcord and press studs to create a snug footbox so your legs don't slip out in the middle of the night. Four adjustable straps secure your sleeping pad so you don't slip off halfway through the night.

  • Lightweight quilt for ultralight backpacking and cycle touring
  • 40-degree temperature rating ideal for summer trips
  • Lofty and compressible Ultra-Dry Down resists moisture
  • Zipperless design with foot drawcord with pad retainer straps
  • Item #STS002K

Love it so much I bought two

  • Familiarity: I've put it through the wringer

This is the perfect three season bag for ultralight bikepacking and backpacking. I use it with a pad and a bivvy and stay warm down to the low 40s. It packs down tiny and weighs nothing. I bought a second one to try to layer with the first one for winter camping and figure it will be perfect for my boyfriend to use in the warmer months since he didn’t have a lightweight bag. I’ve gone to bed with this quilt after literally getting poured on all day and woken up toasty warm and dry. Note that it doesn’t protect from the wind so Depending on the temperature you’ll need a bivvy, tent, etc.

It can be tricky to fit it over top of your pad especially if it is raining so what I do is put the bag over the pad and strap it around the back of the pad and then put it in my bivvy before I head out into the woods so that all I have to do when I get to camp is roll out the bivvy and blow up the pad and my bed is all ready.

This is not a sleeping bag

  • Familiarity: I returned this product before using it

This is an interesting product/concept but not at all what I was expecting. Its really a quilt that straps around your sleeping pad. As I don't like using a liner I don't think I'll be keeping this. It packs down tiny and feels really well made, but I don't like the idea of nothing between me and my pad and don't want to have to carry a liner.
