Great bag

Has a bunch of neat features I like like the interior pockets and shoulder baffles. I've been using it for about a year now with probably 20 nights spent in it, and I love it.

Still Not there :(

Hello dear team,

Unfortunately the sleeping bag has still not arrived. It's probably stuck in customs. I would be happy to rate the sleeping bag as soon as it arrives.

Best regards from Berlin

NZ 20 Mummy Sleeping Bag

Haven’t had this bag long enough to give full review yet. Seems to be made very well and so far the warm of the bag is great. Thank you and kind regards.

Great Bag

Super warm and well made. Used in 20 degree weather in the snow on two seperate trips (Sierra's) and didn't have any issues. Looking to purchase the Peralta 25 next for backpacking trips that aren't as cold.
