It's not as compact as down, but it is light, small, and as warm as advertised. The spiral stitching holds the bag close to keep you warm, yet allows full and easy flopping around, which I do.

I bought this bag for late spring to early fall backpack and bikepacking trips. Budget, size, weight and warmth were the key factors. Down was out of my range.

I compared several similar bags in stores and the Montbell stood out as the clear leader. The bag sleeps just as advertised. Good for me to 35deg if I have on a light pair of long johns. It breathes as well as any other bag I have tried. The spiral stitch makes a huge difference in comfort and being able to move around in what is effectively a mor snug bag. I'm 6'1 with large feet and the long bag is perfect.

I've spent more than 50 nights in the bag with no signs of wear or break down. For the price, pack size and weight it is a great bag.

Retailers' Descriptions

Here's what other sites are saying:

The Mont Bell Burrow Bag #5 Sleeping Bag has brought extreme comfort and thermal efficiency to the light weight backcountry enthusiast. To create an even more comfortable system, an elasticized thread in the stitch to create small "gathers" in the quilting. These innovations allow the sleeping bag to move with you as you change positions throughout the night, drawing the hydro-phobic insulation closer to your body and eliminating drafty dead spaces.


The 40-degree MontBell Super Spiral Burrow #5 Sleeping Bag won't mind if it gets a little soggy on your spring, summer, and fall trips--the silicon-coated synthetic insulation dishes out pleasant warmth despite drizzle and dew. And if you hate that mummified-in-a-bag feeling, you'll appreciate the unique stitch design and stretchy thread that just might leave you wondering if you should stay away from home a bit longer.
