Love that it unzips completely as I hate being confined by reg sleeping bags

I used this last fall on a trip to the Ozarks. I slept in what was basically a thin-walled cabin with outside temps from 36f to 55f and was comfortable all night long. Love that it unzips completely as I hate being confined by reg sleeping bags

Warm and toasty sleeping bag

We bought this sleeping bag for our son to use when he went to science camp . He went during the coldest time of the year and said he was nice and warm the whole night . Quality of the zipper and the material seems pretty good . We will be buying a couple more for our other children to use during our camping trips to the beach which can get pretty cold at night .

Ended up being perfect

Great sleeping bag. I never really got cold or sweaty. Slept in Shenandoah Valley. Got down to low 60s at night.comfortable material. The inside is not silky, it is like the inside of a winter jacket.

Great deal. Material seems better than other sleeping bags ...

Great deal. Material seems better than other sleeping bags at this price point. Kept my daughter warm and cozy on camp out (in mild temps.) Disappointed there is no strap to keep the bag rolled up. The outer bag it comes with is nice though.

Very soft and plush

Very soft, comfortable material and not to heavy but not to lightweight either! Great buy

Not enough items available. Only [max] left.
