Love the new updates to the bag liners!

I've purchased the older version that's the super warm ones for fall camping in Colorado and it was super warm but a little bit challenging for me as I like to poke my feet out of the sleeping bag when I run hot. This design is superb with the option to cinch the feet and the snap buttons on top, really made it much user friendly for someone like me. This material is cooling, perfect for the upcoming summer camping. Super soft material, made it very easy to sleep in. Totally would recommend!

Like a Bed Sheet but in the outdoors!

[This review was collected as part of a promotion.] for the hot summer months and for those cold nights that you need something else. i mainly use this to cool down my body when it gets too warm but need that extra layer just to stay cool, in the summer this works well with a light blanket. and for the winter i use it to keep my quilt clean but still keep myself cool if it gets too hot, it adds extra layer of warmth because of all the heat being trapped and it is very cozy for sure i love this and planning to buy more.

You NEED a liner as nice as this!

First of all, you NEED a liner for your sleeping bag. If you wash your bedding at home once a week—that being under ideal hygienic conditions where you shower every single day—you really don't want that funk getting into your expensive sleeping bag! That's where a liner really helps! This liner is an upgrade for me. I've been using a Sea-to-Summit Comfort Blend for several years, and I've really liked that product a lot. But I thought a back-up liner might be nice. But I was really blown away with how nice the Breeze liner is! Mine is the regular Mummy style, and I really appreciate the soft, wicking material that the Breeze is constructed from. Apparently it's a similar material as the Tek towels (I think…maybe its one of the other towels?). I sleep hot, and I sweat a lot at night, so drawing that moisture off is a really nice feature. To help regulate my comfort (including at home) I usually stick my feet out of the end of the bed (and of the liner), so the opening at the bottom is actually a really welcome feature! Yeah…I don't wander the campsite in my liner, but I suppose you could if you wanted to. To each their own! Anyhow, I really love my new liner. What WAS going to be a spare is now my go-to!

Super soft sleeping bag liner

[This review was collected as part of a promotion.] When selecting my sample, I thought I had chosen a sleeping bag, so was slightly disappointed that this was just a liner; however I love the color and the material is super soft, durable, cooling and thin enough to easily package away.

Amazing product

I don't normally give five stars, but I really like this product. I have the mummy version and love the drawstring bottom and snaps at the top. The snaps at the top mean you can have your arms free which is great for people who sleep with their hands behind or above their head. It is so easy to wash compared to a sleeping bag. I also have a Reactor liner and the Breeze liner is noticeably cooler to the touch. This is a great product for camping on warm summer nights!

Genius Product!

[This review was collected as part of a promotion.] This sleeping bag liner is genius. I never knew sleeping bag liners were a thing until we got this product. It's so easy to wash and will keep the sleeping bag clean. I never wanted to wash our sleeping bags because it's such a pain. I love how lightweight it is. I'm a hot sleeper plus I live in Texas, so this liner will honestly be enough even without the sleeping bag most of the time. I also love the idea of being able to use it in hotels or in travel situations if I'm concerned about cleanliness. It's easy to pack and takes up almost no space. I'm so happy to have this liner.

Great liner for summer camping!

[This review was collected as part of a promotion.] This liner is very soft, I haven’t been able to use it since it’s still too cold in Oregon to go camping but I love the material, definitely going to be great to have the coolmax moisture whicking this summer when it’s hot!

Cooling Sensation

[This review was collected as part of a promotion.] I was happy to test out the Sea to Summit Breeze Sleeping Bag Liner complimentary through Influenster in exchange for my honest review. I had never thought of using a liner before being introduced to this product, but this is actually quite useful. As someone who tends to get hot quite easily, especially while sleeping, this felt great on the skin. As soon as you envelope yourself in this liner, you get a nice cooling effect. The material is soft, lightweight and allows for movement, which adds to a comfortable sleep. This liner is shaped nicely with a hood, arm holes and an open bottom, so you could just wear this out and pull up the bottom if you need to get out of your sleeping bag in the middle of the night, and therefore, not leave this to get tangled in the bottom of the bag or struggle to get comfortably around you. I did notice the cooling sensation wear off while I slept, but I did not wake up drenched in sweat or feel like I was overheating as I often do. I hand washed this in cold and hung it to dry and it was dry within the day. I believe with proper care this will hold up nicely as long as you do not snag it. Also, this comes with a travel pouch and takes up very little space and would be easy to travel with. I'm very pleased with this product and find it to be a useful solution to hot sleepers like myself.
