Best Sleeping Bag I’ve Ever

Best sleeping bag I’ve ever used, and it’s not even close.

Great Light Weight Bag

Light weight and packs small. My favorite bike packing bag! I also prefer the fabric feel to some comparable bags from other brands.

Great Product. Super Light And

Great product. Super light and warm. Not just for camping but also for staying in hostels during our walk across Spain.

Ultralight High Quality, A Bit Tight

Great lightweight sleeping bag! Packs down incredibly small. I would say 32F is a survival limit, not a comfort limit. I’ve had a few uncomfortable nights around freezing temps trying to push this limit with a sleeping bag liner and, well, I didn't die so that was cool. My only complaint about this bag is that the knees are very narrow so there is really only room for your legs to be straight down. My hip muscles were always mad at me after using this bag.

Really Capable

I have only tried a handful of sleeping bags as i'm pretty much a rookie hiker. However i am absolutely amazed by how this bag performs. I can compress it to the size of a football! thisi is reallt usefull to me when i go bike packing, when pack size is important. I always use a small liner, but i have never had any chills in this bag. even at around 0 degrees celcius. some people mention it is is chilly, but it seems most of those people are using the uber lite, or some similar sleeping mat. end of the day im super impressed with its weight to warmth ratio and it has yet to let me down!
