Product Reviews
Rated 5 out of 5 by from Great so far! I just came back from a night of winter camping with this bag so I figured I'd write up a review while it's fresh. I paired the bag with Klymit Static v Lux SL. Since it was around 25°F I also had reflectix under a wool sheet under the sleeping pad. I didn't want to be cold. I'm 6' 280lbs and got the wide long. I had the best sleeping bag experience. Between the pillow barn and being able to move your legs within the bag knowing that you're on the pad is really nice. When rolling over you don't get tangled up in the bag. I likened it to when a massage therapist holds the sheets over you while you roll over. :) I was incredibly comfortable and warm when I woke up. I definitely recommend this bag. After I bought it I had slight buyers remorse as the AnvilHorn is the down version of this bag. I was able to fit the Lost Dog into the bottom of an 80L bag and the weight difference is negligible to me, so I'm happy with what I've got and I'll save the 100. If you're on the fence about this, make sure you use a good insulated pad and you'll be happy. I'd like to get a Big Agnes Rapide SL as I don't trust my Klymit with their shady R values.

Rated 5 out of 5 by from I Love Big Agnes Bags Big Agnes makes incredible sleeping bags! I'm a hugs fan. This is my third Big Agnes bag; I have them for the varying temperatures that I camp in.... They are comfortable, warm to their stated temperature and the sleeping mat mesh netting makes it so I never fall of my mat at any point during the night.

Rated 5 out of 5 by from Nice bag! Just did a camping trip through crystal, co where it dropped down to 30 at night. Bag kept me warm and slept perfectly. Was easy to hop in, zip up and pass out

Rated 4 out of 5 by from Warm and comfy, but on the bulkier side Great sleeping bag for colder weather - I just used it very comfortably in 30F. However, it's a little bulky for bikepacking, which is what I used it for.

Rated 5 out of 5 by from As good as I’d hoped! Having a bag that keeps my sleeping pad in place is a game changer! Kept me plenty warm too. It was also MUCH lighter than my last backpacking bag which was really important.

Rated 5 out of 5 by from Awesome sleeping bag I bought this bag for a short backpacking trip in the PNW. This thing is super warm and comfy. On my last trip I used a 40° bag and froze my buns off. Two weeks later it was a little cooler at night but with the lost dog 15 it was a game changer for me. I had an inflatable sleep pad that worked ok but I'm going to upgrade to the axl 25x72 asap. I can't say enough good things about this bag.

Rated 5 out of 5 by from Great bag! Comfortable, warm, and light This is a very comfortable bag. I went with the long bag. I'm 6'1" and its comfy but still light enough to pack. I love it, and especially being able to fix my pad into the back. #sweepstakes

Ive read a packed size of 9×12" but nothing the other way. Does anyone have an osprey 70 liter backpack n if so will this lost dog 15 degree (non UL) fit in the little sleeping bag comparment without taking the divider out?

Asked by: Zachary Magpul
Hi Zachary Magpul, thanks for the question This sleeping bag sadly will not fit inside, but it will fit under the strap on the outside! I hope this helps!
