Enhanced breathability allows you to leave the jacket on for longer and through a wide range of activities like day hiking, backpacking, cross-country skiing, biking and mountaineering.
The construction of the gloves seems good. I do worry though about how abrasion-resistant the outer glove is. I find the gloves are a little snug to put on, but once on they fit well, so I'd make sure you measure to determine the correct fit, and don't go up a size. For moderately active days, I find these keep my hands warm when the temps get into the mid 30s. When less active, with wind chills in the low 20s, I found my fingers still got pretty cold.
I really like the feel and build quality of the pants. I wish i would have ordered a size smaller but they are still a great piece of kit. They feel like PJs and I love the pocket placement.
I'm fan of Beyond Clothing and bought several clothes including MC Made in USA, good quality and excellent design for personal use, will keep an eye on special offers
