My New Friend
Its a big pack, 7850 cubic inches. My old one was around 6500 and I found that during the winter I ran short of room for extra layers. That led to using compression sacks which is not the best thing to do if you expect to have fluffy clothes available to you when you get cold, its best to leave them fluffed.
I was a bit worried my military sleep system might not fit in the sleeping bag compartment but it slid right in no problem. If you are unfamiliar with that it’s a 3 piece system consisting of a light weight sleeping bag (30 degrees), a heavy weight one (0 degrees) and a goretex bivy cover. You simply mix and match to accommodate the climate down to a whopping -40 degrees. (lower if you leave some long underwear on).
Its a big upgrade (and an expensive one) and I’m pretty pumped about it. It still has the ‘new stuff’ smell and I’m drinking it in. I’ll go get it dirty at the soonest opportunity so I have to enjoy it whilst I can.
Educational Addendum: It’s important to note that the temperature ratings given for my sleeping bag come with a caveat, the military has rated them for those temperatures for 4 hours. Most civilian manufactures leave the time off of their ratings. That means if you buy a bag rated for 30 degrees and its 30 degrees out, don’t expect to be comfortable for very long. I’m not sure what the industry standard is for how long the bag has to be comfortable at a given temperature, but most civilian buyers don’t want to hear that they may only get X hours of sleep before getting cold so they leave that bit of information off.
Your best bet is to leave a 20-25 degree buffer between the rating on your bag and the temperatures you reasonably expect to encounter.
