Mountain Hardwear  AirMesh Long-Sleeve Hoody - Women's

This is designed to be loose fitting (a good thing, but uncommon). I wear a size small for fitted shirts and usually wear a medium for technical items that I want to be loose or layer with. I ordered this in a medium and it's huge! I'd stick to your true size with this. Also, I was willing to forgive the weird zipper pocket because I thought I could fit my phone in it, but it's too small. This pocket makes no sense. I'm returning this mostly because it's just a lot thinner than I realized it would be. I knew it was going to be minimal and it's probably good at what it's intended to do, but it doesn't seem like it's going to be any warmer than the minimal fleece I already have.

I have an older generation of this hoodie. It took me a while to figure out how to use it, and once I did, I was wearing it all the time for running, XC and alpine skiing. So I bought a second one. It insulates while allowing air flow, so it's great for high-output activities. I often pair it with a windbreaker, which comes off as I heat up. The newer version does not seem to be quite as air-permeable, so I will reserve it for colder days. It also has a small zipper pocket, which is great for a car key and credit card.

I wore this for a big through hike as my warm layer. It’s ultra lightweight, packs down small and keeps you warm when you need it. I love this hoodie.

I didn't bother to try these on. I bought them in two sizes hoping one would fit. However, I only needed to touch them to know I was going to return them.They are made with a fabric I can't bear to touch, much less wear. It may be just me, but the fabric feels like touching cotton candy, sticky and a little gross. Otherwise, they are fine. If texture isn't an issue for you, you may be well pleased with this product. It's not for me.

I love this shirt. It keeps you the perfect temp - the mesh allows air in, and the fleece material on the inside keeps you warm. I wore it on a shady hike on a pretty warm day, and honestly, I forgot I was wearing it. I’m taking it with me on my hike of the tour du mont Blanc and expect it will be great for layering. It’s also so light and packs down!!

Weird fabric, I have no idea why anyone would make this fabric. It was porous mesh like material with like a furry fabric underneath. I didn’t even attempt to wear this after just trying it on. Itchy and not warm.

The air mesh fleece is warm, super lightweight for travel and very comfortable-all the things I was looking for. And the fact that it’s reversible provides two different looks. Great purchase.

Bought this for my first backpacking trip. I sized down and it was a little snug, but better fitting under a rain jacket. I stayed warm and dry.

I used it as a layer for resort skiing and liked it. I wore it under a puffy. Kept my temperature well regulated.

Neat reversible option! Fuzzy inside and smooth fabric outside, good for all seasons!
