I bought these to wear as a base layer on glacier excursions during an Alaska cruise, and I definitely got my money's worth. They kept me at the right temperature, warm without overheating, and they're thin enough to allow comfortable movement and a full range of motion during activities like canoeing or hiking. The weather on my trip wasn't super cold (certainly warmer than winter in upstate NY), so I can't promise that these will stand up to all conditions, but layering is key anyway and these can provide a good starting point.

I was generally very impressed with the fit; I followed the instructions and ordered a size up, and that was definitely a good idea (although if they're going to *tell* you to order a size up, I don't know why they can't just design the product to fit as expected). The fit was excellent overall; the top is surprisingly flattering (I actually wore it on its own for a while after returning from the excursion), and the legs, while unsurprisingly too long for my 5'3" frame, could be easily rolled up without creating awkward bulk.

My only issue is with the waist band, which is very narrow. The combination of narrow and elastic just isn't a good one, because it leads to uncomfortable biting in that one place. I wish all pants designers would adopt the more comfortable and flattering wide yoga-pant-style waistband. But fortunately there was a relatively straightforward solution to my problem: I just tucked the shirt into the waistband, which significantly increased the comfort at some cost to aesthetics. It was a little bit awkward trying to arrange the relatively long shirt inside the close-fitting pants, but it was completely doable and worth the effort.

Overall, I'm really happy that I bought these, and I'm impressed with the quality given the low price.
