Excellent Quality, Warm And Comfortable1

[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!!!

Great Bag, Too Small .

[This review was collected as part of a promotion.] Great bag, too small . Insulation fantastic and so light!

Perfect Bag!

[This review was collected as part of a promotion.] Packs down super well, love that I can unzip the bottom and walk around LOL. Big fan!

Fabulous Sleeping Bag

[This review was collected as part of a promotion.] Love this sleeping bag. I’m particularly impressed with how small it packs down to and how little it weighs, which is important for me as a bike packer.

Double Spark

[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.
