    Best sleeping bag.

    5 days ago
    [This review was collected as part of a promotion.] I tried this sleeping bag all the way down to 5°F with layered clothing, and it did fantastic. Super comfortable. I highly recommend.

    [This review was collected as part of a promotion.] I've used the Sea to Summit Spark 30 on a few trial runs and am impressed with the quality of the bag, compression sack and storage bag! The sleeping bag has been warm and comfortable and packs well. I'm an avid hiker/thru hiker and this bag is a great addition to my gear closet!!!

    [This review was collected as part of a promotion.] Really a very nice double sleeping bag. Enables a warm sleeper(me) to keep cold sleeper (wife) warm, happy campers! The straps for keeping pads together are a fail. Had to order SToS straps instead.

    [This review was collected as part of a promotion.] I get cold very easy, even in warmer temps. I was so nervous to try out this bag, because it feels super lightweight and airy. I thought it couldn’t possibly be warm enough. I got the chance to test it out recently, and even brought an extra bag just in case I needed to double up. No sir! I slept snug as a bug the entire trip. Not only is it cozy and lightweight, it also packs down small. Perfect for fitting in a suitcase, backpacking, or even alpine.

    [This review was collected as part of a promotion.] Slept great on the air pad and tucked nicely in the spark. Temps down to 30 degrees and woke up with frost on the ground. The 15 degree sleeping bag did great.

    [This review was collected as part of a promotion.] This is a great little bag that I actually use for all sorts of warm weather things, including when I’m traveling in a hotel room and I don’t like the sheets! It also packs into something the size of a Nalgene bottle, which is incredible to me. Great product.
