The Big Agnes Mystic SL 15 Degree Sleeping Bag is an 800-fill down sleeping bag for backpacking or trekking. They're kinda the same thing. The Mystic SL is not only filled with lightweight down, but the down is protected by the featherweight Pertex rip-stop nylon, making the bag silky soft to the touch. The down is treated with DownTek, while the nylon is coated with a durable water repellent, both treatments provide additional water resistance in damp conditions. Less of the worrying on the trail! The integrated pad sleeves ensures you won't roll off the pad in the middle of the night, and a no-draft wedge provides insulation between the bag and the pad. You'll also find a no-draft collar and zipper tube to further resist the cold at openings. Whether you're a right zip or left zip, the Mystic SL reduces the weight on your back and the space inside your bag.
So sorry, but only 4 items are allowed for comparison, so we're comparing the first 4. I blame the gnomes and so should you.
