Great jacket, love it

I used this jacket both in Valley of Fire State Park where it's quite windy and hot, easy to build up temperature and in Zion NP, where it's kinda cold at night. this jacket is very breathable, i had no problem to release the heat inside when I walked in the deserts like terrain. Then a few weeks later I used it in Olympic NP, when it rained a lot during the memorial weekends, but the jacket managed to keep me dry inside. Only little complaint would be the slim fit - it fits me well for the waist and makes me look sharp, but the clothes hem is a bit too tight, sometimes I feel it restrained my ability to move. It will be awesome if it can a double zipper to adjust it

Lightweight and seriously waterproof

Not as durable as I'd expected, since I had to file a warranty claim. But the process was easy and quick and I received a replacement as promised.

Got what I am looking for

I was worried about the slim fit before purchasing. After receiving the jacket, here is what I found out, hopefully can help someone with the same concerns. I am 5'9, 160 lb with 39 chest and 32 waist. The jacket fits me well with a t-shirt and a fleece jacket under it. While it's a slim fit, but still has a little room overall. But putting a down jacket instead of the fleece feels tight. However can still move without issue. Haven't got a chance to try it under inclement weather. with faucet water, the water beads off quickly. But only tried for a few seconds, not extended time. Living in PNW with mild winder and drizzle rain, I intend to use it as a mostly in town jacket with fleece mid layter. Seems can serve my purpose well. The soft feel of fabric definitely helps.

Great packable BC ski shell

Packs much tighter than my last OR shell, Waist length is great for typical BC skiing. Hood fits over helmet so temp regulation is quick and easy. Bright color helps with visibility.

Lifetime warranty

So I always buy OR for their lifetime warranty. They've always made amazing gear. Lately though, their sizing must have changed as all of their smalls got bigger and then they don't have much of a selection of xs. I feel like every company made this move. I was bummed when they did. This item was a warranty exchange which was very quick and smooth and the lady who did the return should get 5 stars for her effort. It's the smallest jacket i could get but still too big. Bummed, wish they had my old jacket and sizing. It still functions amazing though! Just looks big and baggy in shoulders and arms and chest.

GREAT jacket

The Microgravity AscentShell is a wonderful product. It weighs practically nothing and has. Nice hood and will keep me/anyone dry.

Great waterproof jacket

I live in an area where it rains on/off every day for months on end, and this has been my go-to for years. Currently on my 2nd pair of Microgravitys. Pocket space is great, and ascentshell is fantastic in high-humidity areas where goretex isn't as breathable as it needs to be
