Sierra Designs Women’s Get Down 20°: first impressions

Manufactured with a low impact on the environment, the Sierra Designs Women’s Get Down 20° is cozy, comfortable and light, and also gentle on the planet (part of the reason it features in our Best women’s sleeping bags article). This 500-fill, three-season bag uses a water-repelling down that’s PVC-free that also meets the responsible down standard.

The bag’s three-quarter zipper is anti-snag for easy use, and it is placed closer to the ground than in other bags, so that sleepers can fold back the top for a kind of venting that feels more like your bed at home. It comes with a stuff sack.

In the field

Sometimes three-quarter zip bags can feel confining, but this one did not. Partly that’s because the zipper is lower to the ground, so when I opened it all the way, I was able to fold the top of the bag back more completely than other bags with a partial zip (see: How to choose a sleeping bag).

The polyester taffeta liner was silky soft and felt cozy, not cold on my skin. And the zipper didn’t snag when I zipped and unzipped it during the night. When it was chilly, I cinched the hood down to seal in heat.

Sewn-in hang loops at the foot let me hang this bag to air or for storage when I wasn’t using it. The bag had a generous but not sloppy fit with a spacious foot box (there‘s more on finding the right shape for you in our Types of sleeping bag article).

I wasn’t swimming in it, but I was able to change positions during the night without feeling cramped. Side sleepers take note, however: the lower-positioned zipper can be uncomfortable if it ends up under your hip or shoulder. And the weird hand pocket would be better replaced with a zip pocket to hold a headlamp.
