I've never tried a liner before because they usually have synthetic material that doesn't feel very nice. This liner is so comfortable yet breathable. It's perfect for hot weather camping if you put your sleeping bag below you, or as an open comforter above you sleeping inside the liner. It is the perfect combination. Or, to add more warmth sleep with it inside your bag, also to keep your bag clean you can easily just clean the liner. Best thing I've ever used!

Best Liner Yet!

I love this new Comfort Blend Sleeping Bag Liner. I have two other sleeping bag liners from Sea to Summit. The Reactor Extreme and the Cool Max Liner. I prefer the Comfort Blend to both of these and use it the most often. I have used the liner about fifty days this summer and have found it to be versatile across a wide range of conditions and temperatures. It is also holding up very well. I hope to get several seasons of heavy use out of this liner. My favorite design feature of this liner is the shape compared to the others mentioned. It has plenty of room and I never feel cramped. It is the perfect accompaniment to the Ascent Down Sleeping Bag. Thank you Sea to Summit for another great piece of camp gear.

Cozy and toasty

This product was a perfect fit for my sleeping bag and kept me warm at night in the early camping season. The material is soft, comfortable and light weight. It fits all aspects of my sleeping experience. When I sleep, I toss from side to side and the liner gets wrapped up in my legs for a moment then I adjust. It would be nice to have the end snapped into place to get rid of the leg entanglement.

Good sleeping bag saver

Good sleeping bags are expensive and washing them wears them out faster. I like to use liners so that I can just wash the liner and wash the sleeping bag about once a year. By using a liner I can also take my cheaper less insulated sleeping bags and save my best bags for when I really need them. My biggest frustration with liners is that they get tangled up. While I still get tangled up in this liner it is significantly better due to the stretch of the material. This liner is better suited for warmer conditions as it doesn’t add much warmth nor is it really intended to but any additional layer adds something. I haven’t gotten it wet or washed it yet but it seems like it should dry fairly quickly. Most of my camping is out of a hardshell kayak in the winter and ... MoreGood sleeping bags are expensive and washing them wears them out faster.

I haven’t gotten it wet or washed it yet but it seems like it should dry fairly quickly. Most of my camping is out of a hardshell kayak in the winter and spring with lows well below freezing so the quick drying aspect is nice as wet gear can become dangerous. It’s a lot quicker to dry out independent layers than one integrated system. I have the standard rectangular liner but I’m interested in eventually replacing it with the one with the pillow sleeve as I tend to chase my pillow around in the night and pull the liner back up in the bag. The pillow sleeve should solve both of these problems.

Great for hut to hut hiking!

I needed a sleep sack for a few days of hiking hut to hut in Norway. After a lot of shopping around, I landed on this one, and it did not disappoint. Super comfy, breathable, lightweight, small pack-down size. Loved the pillow pocket as well. I'm really happy with this purchase and can't wait to use it again!

Impressed

I thought for sure I would feel trapped and unable to move inside, but that was not the case. Of note, I am 5'4" and 135 lbs, to give you an idea of how much room I had left of the 72" X 31" liner. The other concern I had, was that due to the rectangle shape, I would have more room that I would need to retain heat. But, the type of fabric made it so that the material laid snuggly on and around my body, making it so the unused/unneeded material didn't steal any of my body heat. I would definitely recommend, especially for those of you who prefer rectangular sleeping bags. This liner packs down small, and would be a creature comfort I would pack with me for backpacking trips. There is only one thing (not a deal breaker) that I would like to have added, and that is a ... MoreI thought for sure I would feel trapped and unable to move inside, but that was not the case.

Love love love!

This sleeping bag liner is perfect! I had the original cotton one that has lasted me a lifetime and this is the upgrade. So soft, easy to move around in and not feel claustrophobic. Would 200% recommend!

Perfect for Bikepacking

Perfect for keeping my quilt clean and mosquitoes off my skin. It's soft, quiet, and doesnt hold condensation like the cheaper synthetic liners. It's lightweight and doesn't take up a lot of room in the pack.

Soft and easy to clean

This sleeping bad liner is awesome! It keeps the heat in and makes keeping my sleeping bag clean! I just toss it on the washer when we’re done! It makes things so much easier! Plus it’s soft!

Super soft liner made for comfort and ease

This liner is thin but oh so soft. It feels like a gentle sheet. This is super easy to store inside your sleeping bag while it’s rolled up and very portable. This makes for a great sleep on warmer nights when you just need a little something extra for comfort in your bag. It also has a handy pillow sleeve.
