Description

Not afraid of a little rain, this synthetic bag keeps you warm no matter what you encounter during your trek.

Spring storms and summer river trips might be too wet for a down bag, but the 30-degree synthetic MontBell Super Spiral Burrow #3 Sleeping Bag ensures a warm night after a cold rainstorm interrupts your trip. Thanks to the quick-drying Exceloft synthetic insulation and shingle construction, even the cold, damp mornings won't chill you to the bone.
  • Rated down to 30F, this bag is best suited for most spring through fall camping and mild-to-cool nights in the mountains
  • Exceloft synthetic insulation works best in rainy, muggy or wet conditions like a river trip or rainy Appalachian excursion
  • Tough nylon outer shell withstands trail abuse and a DWR coating prevents moisture from seeping inside
  • A draft tube inside the zipper and adjustable hood seal you off from exceptionally cold air
  • Super Spiral-Stretch System uses a biased cut fabric, elastic stitch, and gathers in the quilting so the bag stretches with your movements, keeps the down close to your skin, and eliminates dead airspace
  • Auto-locking zipper doesn't move during the night and joins your bag with another MontBell bag; left and right zippers available (depending on inventory)
  • Compression stuff sack packs the bag down to its 7.5 x 14.8in size (regular)
  • Available for shipping only to US and Canadian addresses

Just received bag.

WOW! So many positives........I was back and forth between this bag and the Sierra Designs Utoia and after trying them both out, I am definitely glad that I chose the Montbell. Better stitching, zipper is much smoother, softer feel, EN tested, and it's 4-5oz. lighter!
Weight rating seems to be accurate. Very light for a syn. bag.
Included stuff sack has two drawstrings. 1 to close up the bag and second to condense the sack down. It's not a compression sack, but the second draw string cuts the stuff size to about 14" x 7" (not bad at all for a synthetic).
I've only had it for a day so I can't speak to temp. rating, but I did sleep with it as a top quilt last night in bed and this bag is VERY soft and comfortable.
I will be using this as a TQ and sleeping bag in my hammock for 3 season camping. Footbox is roomy and has enough coverage for a comfortable hammock lay.
I am 5'9 and bought the regular. I would recommend the long for anyone taller. This is the first bag I've ever used that my feet touched the end when my head was in the hood.
I am a wide man and bag fit me very well. I love the stretch that this bag affords.
Hopefully I will have it in the woods in the next few weeks and can provide a field experience review.

Update: This bag works GREAT in my hammock. The stretch really allows me to move around and maintain full coverage. I'm a large man (more round than tall) and I still have TONS of room in this bag when I need it. The stretch gives me the best of both worlds.
I just tried this bag in several sizes of the Sea to Summit eVent compression sack and it actually fit nicely in the SMALL, 10L sack. I was able to stuff it down enough to get 4 rolls of the top closure. The small sack really gets this bag super condensed.
I've used this bag 6 nights in the woods so far and every night I've been more pleased with the purchase.

Not bad

I've only used this bag a few times, but excited to use it more. I think '30 degree' rating is sort of pushing it (I spent two 40 degree nights in Big Sur and found myself shivering a points, but don't plan on using the bag in much colder situations than that. Its cool and light and packs pretty small. Color is great (was definitely a factor in my purchase), though the finish is much more fake rubber / plastic baggy than it looks in the pictures.

I use this bag 3 seasons , its warm , light, packs small. In the summer I usually open it up and use it as a top quilt. It feels much better on the skin than most bags. Even though this is a mummy style bag, when your zipped up inside you can stretch around a lot, it expands quite a bit more than you would think. I have never had a moisture problem. No problem staying warm at 30 degrees but I sleep warm. It also performs well in a hammock zipped up (because it stretches) or as a top quilt.
