This is a very flexible and lightweight jacket. I initially had some concerns about durability due to the light weight of the jacket, but it is proving quite durable. It's best use seems to be as a wind blocking layer. The tight weave of the material blocks wind and grit. I have mostly used it on short hikes and daily walking the dog in temperatures ranging from -24C to +16C. It works well during high output activities in colder weather when combined with a fleece sweater and/or long underwear top. In warmer weather opening the front zipper provides adequate ventilation when combined with the breathability of the fabric. The only con I have found is that the sleeve length may be slightly short for someone with longer than average arms. If you have gloves with normal cuffs then it would likely not be an issue.
