Slumberjack Red Warming Sleeping Bag Liner

very nice sleeping liner. rectangle design but will still fit into a mummy bag easily. very lightweight and convenient for backpacking and will be needed this fall/ winter

Great sleeping bag liner that adds a little extra warmth to your sleeping bag on cold nights. Already had the cooling liner from the same brand and wanted a line for this spring and fall trips to add warmth. Sleeping bag liners are a must have in premium sleeping bags helping keep the inside of a bag clean as well so you can avoid washing the sleeping bag itself as often.

Super soft and definitely helps maintain heat

added to a sleeping blanket and performed perfectly for by the lake mtn camping. 1000% approve

Soft, stretchy, warm. Perfect sleeping bag liner for extra warmth.

very soft, easy storage, bag is very solid only down side would be compression straps but for the price cant beat it

This liner fits my sleeping bag great and adds coziness and warmth. Nice quality - very well made. Keeps the bag clean too! Washes and drys great- cold water, low heat, no fabric softener. It is 34" wide by 80" long. Carry weight just a little over 1 pound!! Easy to carry. Comes in a nice carrying case too. A lot of work getting it back in the carry case tho .... Right now it is in my 4 yr old Granddaughters bed. She loves it. So ,.... great use for fun at home too.

This sleeping bag liner is unbelievable! It's a very thin, soft and comfortable material so its hard to believe that it will actually keep you super warm. But, it does! I like that it packs super small, has its own carry bag, and most of all, that it works! Kept me warm while camping on 40 degree nights. Not just warm, but comfortable and flexible. I'm not into being wrapped up mummy in a sleeping bag. I need flexibility to move around. This liner provides that flexibility.

Great price point for sleeping bag liner, comes with carry bag and is easy to fit back in. I haven't been able to test it out yet camping, but it feels soft and comfortable, thinner than I expected. I bought it for protecting an expensive sleeping bag and hopefully adding some warmth during winter camping. I think it will work really well for what I need it for. If I ever try to do ultralight, then I will spend the insane $$ on a fancier liner.

The liner is a medium to light-weight, soft and stretchy jersey-like material. I appreciate the length. However, this type of product needs to come with a zipper for easy entering and exiting.
