>>208362you can sleep outside in -30C in the USMC bag, its specifically made for NOT sleeping in a tent, but for a trip to antarctica i would use one of those 500$ bitches if i had the money.
for most the USMC bag is best because its less than half the price of similar 0F bags on that site, more durable, modular, has a 5 star bivy bag and the compression sack it comes with its the best sleeping bag bag ive ever come across. taking out and putting away the bag is hassle free.
not to mention, the ones my bro and i have bought were woodland camo from the 90s, and his was new unissued. i cant be the only one who finds high visibility disgusting.
