Details

Enjoy a warm night's sleep wherever your adventures take you.

From summer traverses of jagged mountain ranges to shoulder season treks through the desert, the Therm-a-Rest Women's Mira HD Sleeping Bag provides exceptional warmth and comfort, so you'll be refreshed and ready for another full day on the trail. Now insulated with 750-fill, hydrophobic goose down, this 27-degree, three-season bag will perform well in wet and dry climates alike.

With a women-specific cut, the Mira HD moves volume from the shoulders to the hips for an un-restrictive feel that maintains exceptional warmth. Zoned insulation places more down at the top of the bag where  heat tends to escape, while the Synergylink mattress connectors ensure the bag stays attached to your mattress, letting the mattress do much of the insulation work. A Toeasis foot warmer gives your toes a cozy home, and a full length draft collar and tube prevent warm air from escaping through the zipper and at the top of the bag. Therm-a-Rest's own Thermacapture lining reflects heat back at your body of even more warmth so you'll sleep great whether you're perched in a mountain cirque or nestled in a desert canyon somewhere in the Southwest.

My go-to backpacking sleeping bag

  • Familiarity: I've put it through the wringer

I've used this sleeping bag for almost three years now, and it's still going strong. I love the down-filled toe pocket.

I pack it into a compression sack- it's super small and barely takes up any room in my pack.

Full disclosure: I am an employee of Therm-a-Rest

My go-to backpacking sleeping bag

Might be perfect choice for you...

  • Familiarity: I've used it once or twice and have initial impressions

I'm 5'7", 150#, 40" hip, so I went with the long. The bag didn't feel particularly long to me... When I snug the hood the drawstring at the top of the face opening hits me uncomfortably right on the bridge of my nose. If you're truly 6 ft tall, this might feel too short.

This is a generous mummy bag side-to-side. I had enough room to lay on my side with my knee drawn up toward my chest although I felt like my butt was compressing the down and might have gotten cold. With the bag attached to a pad you can squirm around pretty easily inside.

The toe-warmer pocket is a great little features that every bag should have.... it's basically a tongue of down-filled fabric attached on the sides and top of the bag. It's great if you're a back sleeper and/or if you don't attach the bag to a pad so that when you curl up on your side you're also sleeping on the side of the bag leaving your toes in the toewarmer pocket. But if you prefer the bag attached to a pad, when you roll onto your side or stomach it's no longer possible to tuck your toes into the pocket because the opening is still facing up. And your face in no longer in the hole for the hood of course... but no one has resolved that problem for me.

The bag is a nice bright red, with a silky feel inside and out. It has 3 pairs of loops to attach a liner if you want to.

If you're looking for a less constricting mummy bag, this is a great choice. I won't ever own another bag that doesn't attach to the pad since I roll around too much and end up on the tent floor. But, this bag ultimately didn't work out for me because the hood fit uncomfortably and it's just a tiny bit too snug for me to really sprawl out in it. Also, really bugs me that it only comes in left zip (unlike most women's bags), since my hubby's is also left zip (like most men's tall bags) so one of us has to have our zipper toward the other person instead of toward the tent wall/door.
