Rating: rated 4 of 5 stars
Design: Mummy
Fill: 775 fill down
Temperature Rating: 15 degrees F
Weight: 2 lb., 4 oz.
Price Paid: $200

I've had the opportunity to test this bag at 12,800 feet in Colorado's San Juans in August, among other places. The bag is exceptionally roomy for bigger guys (I'm 5-11, 215 lbs, size 46 chest--tried the Zirkel first but found it far too confining in the chest and shoulders).

The draft collar is nice and adds a little warmth. You must use a sleeping pad with this bag since it has no fill in the bottom half (I use BA's REM Insulated Air Core). This design is both good and bad. Good, in that it's almost like being in your bed at home under a blanket, and your bag won't slide off the pad during the night. Bad, in that the bag won't move with you if you change positions frequently (though it's so roomy that this isn't a big issue for me).

Also, I found that on very cold alpine nights (high teens/low 20's) I could detect cold spots where the bag joins the pad. There's supposed to be enough overlap to prevent this, but it's not perfect. This, combined with the low efficiency (due to its size), I think the 15-degree rating is a bit optimistic. It's more like a 20-25 degree bag, though I am an average-to-cold sleeper and like to be toasty.

That aside, it is pretty light, packs small, and is well-made. Overall, a good bag.

The Big Agnes Mystic Sleeping Bag is filled with light, compressible 800 fill DownTek waterproof down and weighs only 2 lb 7 oz. Like all Big Agnes sleeping bags, the Mystic has an integrated pad sleeve so you never roll off your pad again. Removing the insulation on the bottom also reduces weight since compressed down has no insulating effect. The Mystic is an upgraded version of the popular Big Agnes Lost Ranger Sleeping Bag. Flow Construction: Insotect Flow is a flow-optimized insulation system that delivers uniform heat distribution and natural body contouring through its revolutionary baffle design. Flow Construction eliminates lateral and vertical down shifting by using vertical chambers with Flow Gates to regulate fill positioning and density. Strategically placed Flow Gates minimize vertical down shifting while vertical chambers minimize lateral shifting. With continuous vertical Flow chambers in place of traditional side seams, Flow bags eliminate potential cold spots which can occur with side seams. Vertical baffles now flow with your body for more rapid and uniform body heat distribution.

When you're trying to minimize space and maximize warmth, the Big Agnes Mystic 15F Sleeping Bag is just the ticket. Even though this three-season sleeping bag weighs in at a paltry 2lb 4oz (regular), it doesn't skimp on comfort. High-loft 775-fill goose down retains your body heat, a rectangular shape adds room in the foot box and shoulders, and a no-draft yoke seals blocks cold drafts. Meanwhile, the WRM nylon shell material resists water, blocks wind, and breathes well. Big Agnes integrated a non-insulated sleeve that fits a 20-inch wide rectangular sleeping pad. This reduces weight and bulk and ensures you never roll off your pad again.
