what temperature rating and/or thermal r value does this jacket provide? I'm thinking of buying it for an AT trail fall/winter (sep/oct) MD section hike.
My husband bought this jacket this past winter and wore it every day. We live in Orono, Maine, which gets quite chilly in the winter! Temperatures are often in the teens in January and February. My husband walked 2 miles to and from work (4 miles total) every day and always found this jacket to be warm enough (he could also wear this jacket in more mild weather and it would keep him warm but would not overheat him). He did not need a sweater underneath the jacket to keep him warm. That being said, this is the first winter that my husband has actually owned a winter jacket. Prior to last winter he would merely layer up with sweaters and a vest or thin jacket. In other words, he is accustomed to the cold weather and has quite a high tolerance for it. But if you're the type of person who often feels cold/chilly when outside in the winter and really needs to bundle up then I wonder if you'd find this jacket warm enough. But MD rarely sees the frigid temperatures that we see up here in Maine so you may be just fine. Lastly, I would be worried about this jacket snagging on branches while hiking. The outer material is thin and seems very snaggable (seems to be the same outer material as the down sweater); but my husband never used this jacket for hiking. I hope this answer was somewhat helpful! Good luck finding a jacket!
the high loft jacket is well insulated. I would feel comfortable taking
on the AT in the sep.oct time frame.
If you have a waterproof jacket, preferably goretex, you would be good for winter conditions.
