Marmot Wraptor Down 15 Review

Warmth

You may be wondering: “Does removing the zipper mean the bag will be drafty?” We'd argue that the overlapping flaps work as well as, if not better than, a zipper with a draft tube. With 26 ounces of 650 fill-power duck down in its many baffles, the Wraptor 15 is well insulated.

It received an ISO-tested comfort rating of 22°F and a lower limit of 11°F, with Marmot themselves marketing it as a 15°F bag. During our testing, with temperatures dropping into freezing territory, we felt plenty warm and experienced zero cold drafts. It certainly felt like we would still be comfortable in even lower temperatures.

Plus, with no zipper in the way, the Wraptor 15 offers plenty of ventilation – every flap and fold is a spot where you can poke out an arm or a leg. And with an envelope-style foot vent, you can even poke your feet out of the bottom of the bag. With the snaps undone, you can use it more like an open quilt.

Weight

The Marmot Wraptor Down 15 is available in standard, short, and long sizes. We tested the standard version and weighed it in at 2 pounds 14.4 ounces, with the compression sack adding another 4.1 ounces.

The 650 fill-power duck down isn't the most efficient insulation — higher-quality down exists — which is why Marmot needed to pack a lot of it in to make this a reliably warm sleeping bag. That substantial amount of down fill, and the overlapping flaps, add extra ounces, making this a nearly 3-pound sleeping bag.

Comfort

The lack of a hard zipper to rub up against or roll over makes the Marmot Wraptor 15 delightfully comfortable. Coupled with the overlapping duck down-filled flaps, this bag is 100% plush fluff. The Wraptor 15 is still a mummy bag, which can feel restrictive, especially if you're used to oversized, rectangular sleeping bags common to car camping. But you don't feel that sense of constraint in this bag.

The 60-inch shoulder girth is fairly standard for a mummy shape, but the 64.6-inch hip girth is unusually generous. More importantly, the overlapping flaps and snaps don't lock your torso into a fixed position the way a full-length side zipper can — there's extra wiggle room since the flaps are much less rigid than a closed zipper.

Back sleepers can keep the default mummy shape if they want, and side sleepers can use the extra space to spread out a little. Especially since you can poke a leg or arm out from under a flap, we slept comfortably in almost any position.

Packed Size

The Wraptor Down 15 packs down well, especially considering its weight and mid-quality fill. We measured the packed volume at exactly 8 liters, which is pretty good.

Higher-quality down, of course, would compress even more, but we had no trouble fitting the packed Wraptor 15 in our backpacks.

Features

The unique design of the Wraptor 15 creates its own features – such as the flaps and snaps – but there are a few others worth noting as well.

The magnetic Fidlock closure at the shoulder is a fantastic design choice. Rather than adding another basic snap, this closure is easier to lock and unlock with one hand. It locks securely, so you won't have to worry about it coming undone in the middle of a cold night.

If there is one aspect to gripe about, the snaps can be a little difficult to find in the dark. Their placement isn't as intuitive as a zipper pull, so if you wake up cold in the middle of the night, you may have to dig around in those puffy layers before you can find both ends of each snap.

Common features include a small stash pocket and a quality hood drawcord, and one more thoughtful extra is the envelope-style footbox. It's a fun feature that's surprisingly practical – for a sleeping bag that's already easier to ventilate than a traditional mummy bag, this footbox only makes the Wraptor 15 that much more versatile for warmer summer trips.

Should You Buy the Marmot Wraptor Down 15?

The Wraptor 15 really feels like being wrapped in a blanket at home – if you prioritize warmth and comfort, this bag should be at the top of your list. If you're of the mindset that ounces matter, and you're willing to sacrifice a bit of comfort for weight savings, you'll likely want a sleeping bag that weighs less and packs down smaller.

What Other Backpacking Sleeping Bags Should You Consider?

We'd recommend the Wrapter 15 to any backpacker, from casual to serious trips. For thru-hikers who want to keep their kits as ultralight as possible, you'll likely need to step up in price if you want a bag that's this warm and lighter. The Western Mountaineering UltraLite, for example, is just as warm as, if not warmer than, the Wraptor 15, but it's more than a pound lighter. Going the other direction, the Exped Terra 15 is just as warm and a bit cheaper, though not quite as comfortable or adaptable as the Wraptor 15.
