Comfortable, true to size. Windproofing is incredible. Makes a thermal jersey comfortable in temperatures 10 degrees colder. High quality construction. Can't speak for durability yet.
The reason to buy this is the windproofing--if you normally wear a windproof gillet, this won't do any more for you than a regular thermal undershirt.
Downsides: price (over $100 for fully synthetic--I would have expected merino for the non-windproof portions at this price point), care (wash inside out, remove immediately, line dry only), tag (large and scratchy and hard to remove). Still a five star base layer, just not "perfect".
These are perfect for rain and a bit of warmth.
The 2-part velcro closures in back make a perfect fit and make it easier to put on.
Size L fit both my size 43 Lake road shoes as well as my size 43.5 Sidi mountain shoes. However, I needed XL for my Shimano size 44 Shimano SH-EX300 "city" shoe that's more of a tennis shoe style.
Luckily, the XL works well for all those shoes, including the size 43 road shoes. So, don't be afraid to size up.
Haven't had a chance to check how rainproof these gloves are but wore them just once on a cool cloudy day with light sprinkles. I suspect they will keep my hands dry. But . . . their fit is small, quite small. Further, the inner portion of the glove, made of a felt-like material pulled partially out when I removed my hands. It took several minutes to get the gloves back to their original state. I'll try again soon as an extended period of rain is forecast.
