Boosts the season

[This review was collected as part of a promotion.] I like this one with the hood better than the un-hooded.

Not For Me But My Husband Likes His

[This review was collected as part of a promotion.] I was hesitant to leave this review but honest reviews are important and everyone sleeps differently. | did not like sleeping in the liner, I found because it was polyester I sweat and was uncomfortable. I was hopeful because my husband has the warmer Reactor liner and uses it in the colder months and likes it. I had to move to a merino wool liner.

Bag liner

[This review was collected as part of a promotion.] Used this liner at 20k and it was that little bit of extra I wanted. Not much extra weight for a lot of extra warmth.

Very nice

[This review was collected as part of a promotion.] Packaging is a breeze and easy to. It’s seamless to set up and unpack and get situated I can’t tell much on the warmth as it didn’t fit the situation for insulation but I believe great temperature control .

Super cozy and great for all heights!

[This review was collected as part of a promotion.] I love the material of this sleeping bag! It provides the perfect amount of warmth without getting too hot especially with living in the south. I also love that it is big enough light to fit people of all heights up to 6’6”.

Excellent Layer For Cold Nights

I wanted something I could use during the early camping season in the high country and desert of the Four Corners Region and this works perfectly. I have a double wide 30 degree sleeping bag that I use and in the early spring it still gets cold in the lower mountains. Even in the desert there are cold nights and Im tired of sleeping in my skiing base layers these nights. I've used this liner three times now and love it. The first time was in early April in the desert and it got down to 42 at night. I was very comfortable in the sleeping bag by myself with the liner on. It was a little difficult in the middle of the night when nature called but I managed. The second time I used this was around the end of April and beginning of May at an elevation of 7,000 and lows of high 40's. Once again it worked great and was easier to use in the middle of the night. The key was to fully release the feet cord. The last time I used it was just a week ago in the desert with lows of mid 50's. This time I used my hammock & blankets along with the liner. I was warm and comfortable all night. Overall I love this liner and it meets all my needs for a comfortable nights sleep.

BEACH CAMP READY!!

[This review was collected as part of a promotion.] Ready for beach camping! As the beach is cold in the night is SO COSY! the comfort on this liner was amazing. The packability on it, doesn’t add too much space in your beach bag! Fits amazing with you outfit at night and great reflector! Looks like it’s going to have good durability for multiple camping this year! Absolutely recommended.😍

Cozy and compact

[This review was collected as part of a promotion.] This is super lightweight and compact which makes it very travel friendly. The size is pretty great since it opens at both ends and can accommodate many heights. Cozy liner!
