MontBell U.L. Super Stretch Down Hugger #4
The U.L. Super Stretch Down Hugger #4 has been discontinued. If you're looking for something new, check out the best warm weather down sleeping bags for 2023.
The best sleeping bag I've ever slept in. The best night's sleeping on the ground ever.
- Zipper snags
- Stuff sack a bit tight
I love this bag. The best thing for me is the super-stretch feature. I've always felt claustrophobic in mummy bags, and have never slept well in them.
With this bag, I always feel like I have room to toss and turn. Yet it gently hugs your body so there's no dead air space to warm up. This is also the first mummy bag I've owned where I could actually make the hood work the way it's supposed to.
Entry and exit is good, though the zipper often snags when zipping in.
The bag is warm and seems right on its 35° rating. It lofts up quickly after unstuffing, and warms up quickly when you first climb in.
The only other nitpick I have... the stuff sack which came with the bag seemed a bit too small to me. Trying to stuff it in there made me really uncomfortable, and I ended up buying a slightly larger stuff sack than the one supplied. It just felt like I was crushing it awfully small, and I didn't want to destroy it right out of the box.
All in all though, I love this bag and am totally pleased with my purchase.

Overall, I absolutely love this bag. I am a warm sleeper and I also like to be able to stretch out when sleeping. No other bag offers this combination of light weight, room, small stuffed size, and warmth.
I was plenty warm enough sleeping in shorts and a t-shirt on a several night trip in the Bob Marshall Wilderness with night time temperatures in the low 40's. Between this bag and my new Thermarest Neo Air, I slept better than I ever have in the back country.
The only reason I did not give the bag a five star rating is because I have noticed a few small down pieces mysteriously emanating from the bag when I have fluffed it up after pulling it out of the stuff sack. This does give me a bit of concern about the longevity of this bag.
However, I will never buy anything else simply because of the room this bag offers. I plan on buying the #1 15 degree version for my autumn excursions.

It is a good bag, but it does not breath very well, I was totally wet at night.
And when I wanted to wash it according to a washing label - hand wash at 30 degrees C., the first time it was water resistant, and it quickly dryed up, but second washing it did not survive - it soaked all the water ... and it is not allowed to squeeze it... then, I don't know if I can use it again.
There is missing detailed explanation how to take care of it.
Fill: 90% geeze down, 10% feather
I picked up this bag from the MontBell store in Boulder, Colorado, last fall. For summer/fall backpacking this thing puts my old bag to shame. I think it's rated down to 30 F, with 725 down. For the size and weight this bag is incredible. Mine weighs under way two pounds (my scale sucks) and stuffs into a sac the size if a oblong volleyball! Plus it has the Super Stretch thing happining. The bag has elastic stiching, so it flexes and moves with you! I can sit cross-legged inside mine. When I bought my bag (2003) it was the only ultra light model available with a zipper. But now they have a whole new line on their website, all with zippers! I would have to give high marks for construction and materials used. I've used my bag a bunch and every stitch is still lookin good, and the mirco-rip stop shell material is super silky.
It get the 5 stars because of the Super Stretch system, and overall construction.
