Rated 4 out of 5 by from Practical and compact It's hard telling how many degrees of warmth this bag liner can actually add. That being said, I pretty much always bring it, regardless if I think my 0 degree down can give me the warmth I want. That's because of a few things: It keeps my down clean. I can wash it easier since at the end of the day I typically smell like an old soup kitchen. It stops drafts better when I want to unzip the down bag and let out some heat. It takes away that cold clammy feeling of your bags face fabric. It's small and adorable like me. As far as warmth, hard telling. It's about as thick as bed sheet, and pretty compact when rolled up. Would be 5 stars if I actually felt like I was sleeping in a nuclear reactor.

Rated 5 out of 5 by from Lightweight & Comfortable Worth the money. Feels good next to your skin and keeps sleeping bag clean. I have the Marmot Plasma 0 so I really did not need this item for extra warmth but that's a plus. Just throw it in the laundry and your ready for the next adventure.

Rated 5 out of 5 by from Does an excellent job of keeping me perfectly warm I got this product to boost my sleeping bag 20 degrees or so. It can also be used alone for hot weather camping (looking forward to it). But truth be told, I've been using it in bed so far. It's great! I usually overheat somewhere in the middle of the night where I peel back covers and annoy my mate with my radiance. Not any more! There's some kind of magic in this where, even with the same amount of covers, my heat is conducted and moved around. Just perfect. So I warn you, if you get this it might become your new blanky.

Rated 5 out of 5 by from Sleeping in the cold doesn't have to be miserable! Instead of investing in a nice sleeping bag, I pair this with my Coleman bag. Even though the liner is very thin, it definitely adds 10+ degrees. ,,Also came in handy for when I borrowed a friends bag. No one wants to sleep in someones else's sweat and oil! I overlooked how much it helped until I forgot it on a trip with 40 degree nights. I will be double checking for this little guy on all future trips! When packed up, the stuff sack is small and is worth much more than an additional 263 g to your pack. ,,Only complaint is that it's difficult to get into. I typically hammock camp and have to get in the liner before I get into my hammock. ,,In summary, I swear by this liner and would buy it again.,,

Rated 4 out of 5 by from Keeps my bag clean Hey, If you buy thing to keep you warm you might as well eat jalapenos before bedtime. I purchased this for the sole purpose of keeping my oily -ss skin off of the inside of my very expensive ultra-light down sleeping bag. Can it do that? yes it can. If you have any other intention for this device maybe you would like to use it as a bear bag to store all of the pizzas you plan on making during your next adventure to the River of No Return.

Rated 2 out of 5 by from Might be OK as a liner, don't even consider using it as a warm-weather bag I used this backpacking for 5 days on the Ka'u coast (south of Kilauea on the Big Island of Hawai'i.) ,,,,This was only warm enough when I wore a T inside it, and sometimes I needed long pants or a long-sleeved shirt as well. Daytime was sunny and hot nearly every day. Nights were down by the coast; there were steady sea winds with gusts, but I wasn't at any altitude or anything. ,,,,If this isn't warm enough to use as a bag for sleeping inside a tent on the beach in Hawaii, I can't imagine what weather it's warm enough for. I also found I tended to get tangled up in it, as some other reviewers said.,,,,On the plus side, it was incredibly light and super small; I wasn't wasting any pack space or weight by carrying it, but I won't try using it again except as a bag liner.

Rated 2 out of 5 by from Not Worth it I was psyched to get this liner but as soon as I opened it, I was baffled at what I got for the price tag. The fabric was extremely light & practically transparent. I took it backpacking to add warmth to my 0 degree down bag, but it was almost impossible to get into it & it got all twisted & bunched up since the fabric was so light.Once I did get inside it did nothing to keep me warm & it was more frustrating than anything else. It just doesn't seem like it's made of a good fabric, definitely doesn't work when you're trying to sleep with a bunch of layers on already.I ended up switching bags with my boyfriend since I was so cold, & the liner ended up bunched up at his feet. Pretty pointless.

Rated 5 out of 5 by from Leaves My Silk Liner In The Dust! Warm and fuzzy are two over used adjectives. But it's warm and fuzzy! Think coming home from work. All you can think of is getting into your jimjams ... having a glass of wine ... and playing WOW until the early morning hours! It's that good! Winds howling about. Rain pouring down. Yet you are warm and snuggly in your Reactor Plus Liner!
