The Cinder is a lightweight, super-packable quilt protected by a waterproof yet breathable shell. A drawcord pulls the foot end together into a foot box for cooler nights, and three adjustable straps keep the quilt secured to your sleeping mat. Quilts are perfect for weight-conscious backpackers. The lack of a zipper and hood reduces weight and packed volume, and the broad cut provides freedom of movement. Sea to Summit quilts feature the QuiltLock system which allows quilts to connect to a Sea to Summit sleeping bag adding an extra season of warmth.

Living in Korea, cycling is one of the best ways to get out of the capital and see the countryside. That is, if you can pack light enough and have what is "just right" for the season and conditions.This was the first all-down "sleeping bag" I have had, and the "quilt" with open function is, for me, a tosser-and-turner at night, a provider of leg freedom when not at home. The fact that it buckled around the sleeping pad when I feel asleep was perfect so that when in the early morning on the beach I could slip between my pad and quilt, feeling warm enough that I slept in (not usual for me) and slept with enough warmth and leg freedom to make the extra morning hours on the beach relaxing and kept me in the tent.My thoughts are this is a great summer product, and I ... MoreLiving in Korea, cycling is one of the best ways to get out of the capital and see the countryside.

The only question is: when can I next use it!

Very lightweight. Quality is excellent. Wasn’t quite as warm as I was hoping but will just keep for summer backpacking trips.

Good way to layer for colder camping days. I can have a lighter sleeping bad and if it gets too cold at night I can slap this on in the inside and provides the ext a insulation and warmth needed on colder nights with out all the bulk of a warmer sleeping bag.
Great for putting over a sleeping bag ou just a nice summer quilt for warmer nights. Packs down really small and is very lightweight Love it!
I bought the Cinder quilt because I wanted something that could pack down small but still keep me comfortable in moderate cold weather. This quilt did not disappoint, it compresses super small, kept me very warm even around 32 degrees, and packs away easily in my ruck so I can keep more in there. The only down side (which is minuscule) is the foot box is open but has draw strings to close it, I would have preferred it be sewn. Still great product, I’m extremely happy with if.
This quilt is really comfortable and lightweight! Perfect for summer trips and a great add on for winter ones!
I was looking for something during warmer season that isn't a bag. I've tried "normal" blankets, etc and just wasn't 100% happy. Packability was usually the issue, so I decided to try a quilt. It was between this and a few others, but being a fan of seatosummit decided to go with them and couldn't be happier. I've used this sleeping in the bed of my truck, to camping in the Backcountry during fly fishing trips, to sleep on the couch with it. It's high quality, packs down super small, and keeps me warm when needed.
I use this with a silk liner for camping in hot weather. Perfect for hot prairie nights. High quality and even comes with a compression sack to make it super tiny. Love it.
Very light and packs down small. Seems to hug the sleeping mat well enough
