This is high quality sleeping bag, just used it for 5 nights in during our satopanth taal trek in Nov first week where night temperature was -12 to -15 degree Celsius during night and it didn't disappoint us. Worked pretty well and trapped body heat well. It is pretty compact i was carrying in my back pack.
Great quality sleeping bag, supremely toasty on the coldest of nights used recently whilst camping ... only issue makes getting up in the morning hard! Packs down to a really small size no issue getting into the compression sack but also worth mentioning that it comes with a black mesh bag that I assume is for washing and/or home storage. This will be ideal for hiking/camping due to its size and weight. Fantastic product!
