Ultra light weight, compact
Well constructed, very light weight; I keep mine in my travel bag, having been surprised by a trip where when I left temps, were in the mid 60's with no wind, but when I arrived two hours from home for a two day trip, I found high winds and temps in the mid 40's; I had a vest with me and a light jacket, but the wind cut right through my polertec jacket. I've only had one chance to try this jacket out, but it blocks the wind like a much heavier coat, and best of all being as light as it is, it fits in my insulated vests pocket, and if the temps and winds aren't howling, I can unzip it enough to regulate comfort. Haven't had it long enough to judge durability or I'd have given it 5 stars.
Would recommend to a friend.
