Customer Reviews
This is a pretty light and compact bag, you could definitely use it for backpacking. And camping. It's on the thin side, but it does seem warm. It is made of 55% goose down and 55% polyester fill, so it's a mix. I haven't tried it out in the outdoors yet so I'll have to update this post. I do think I would be a bit concerned using it in super cold temps because it is pretty thin... I do like the comfort of this though, unlike a tapered mummy bag you have a bit more space (it's more square), and you still have the top "hood" part that can be cinched up in the cold.
The sleeping bag feels like a super soft puffer jacket. It is very thin though, so you would need a mat or cot under it. It should work well though if you prepare
I used it tent camping at the end of October in the 40s. I was never cold despite how thin it was but to be fair I had brought an extra lightweight blanket. I can��t say how it would perform under 40 degrees but you should be fine to at least that temp without another layer. It��s light, thin and packs easy. Great for the price.
Took this for the first weekend in September camp trip. I was definitely warm despite a cool night (I ended up sleeping in my undies because of the warmth.So nice to have room- and this is a nice replacement for my old mummy style bag. The inside is definitely cozy, not the typical noisy nylon lining, and it��s nice to be able to unzip at your feet.Definitely a good bag that I��ll use for many seasons.
Risponde appieno alle indicazioni del venditore. Consiglio.
