Sastrugi

Update on previous review

I’ve had a few nights to test drive my Sastrugi lately, here’s my results- Two nights in the low twenties, under overhanging branches but no shelter; wearing a large hooded puffy and a warm hat. I slept just fine, plenty warm. No problem with drafts on the hoodless design. I’m generally a warm sleeper, but I’m pretty excited that a comfortable night in those conditions is possible with this bag. If i was ordering again, I’d do the overfill option; I didn’t notice it was so economical. Otherwise no changes.

Outstanding so far!

I’ve been out for a few nights in below freezing temps with it now- I’m a big fan of this concept and the build quality. I’m 5’10”, 185 lbs, and got a 70”x62” 28 degree in brilliant blue. It’s startling how light it felt when I took it out. At first glance I got worried I’d gone too wide, but after the first night I think it’s perfect. With a big puffy inside to boost it to winter temps there’s still room to move. I can pull my knees up and touch my feet- haven’t done that in years in a mummy bag. Awesome, can’t wait for more cozy nights.

Amazing bag for a giant

I am a pretty tall glass of milk at about 6’10” and Nunatak was amazing to work with and get me the bag I needed. I opted for the zipper less sastrugi and it is one of the nicest bags I’ve ever used. Keeps my warm when I cowboy camp up in the NC Appalachians. I can’t complain about anything, bag is flawless, the right size, and packs down small. Only thing that you could complain about is the price. But this is one piece of gear I wouldn’t penny pinch on. Made in USA, small cottage brand, yeah I expected to pay a little more but my options were few and far between anyways because I am a jolly green giant. No on ever says to themselves when they’re out on the trail “oh damn I wish I hadn’t bought this amazing piece of gear that accomplishes everything I need it to.”

The Perfect Bag - NO DRAFTS!

I got a 28F sastrugi w/ overfill and have used it for ~6 nights without baselayers (male sleeper). The highest night was 48F which was almost too hot for this bag, but it worked okay with leaving the top open. You can also just drape the whole bag over you like a blanket or roll it down halfway on warmer nights. Lowest night was 36F which was really cozy.

I was concerned about the entrance/exit with the zipperless design, but it's not really a big deal, and it eliminates the draft, so I'm happy with it!

It would pair nicely with an apex/alpha quilt (or bivy) for a wide range of use.

Also of note - I'm 5'10 170lb male and got the 70"/62"/40" dimensions and it was roomy! Especially in the torso region, you can fit a huge parka in if you want!
