[ Yes, very light but still keep you warm enough to be out at not too warm day. Love the orange bright color. It 's a keeper. I always buy XS bc it 's the only size been offered for petite people as me. Wish has XXS, will fit me better, wo n't be too long.

[ My husband was so embarrassed I kept wearing my previous icebreaker from time to time, even though it become literally threadbare in a couple areas. Was nervous an updated version might not be as good, as often happens when one buys a replacement for something they 've loved so much, but so far this one has the same fit and feel as my beloved first icebreaker shirt. As well, they are usually `` updated '' colors offered and I was glad this one is pretty close to the original. I 'm sure I 'll get as many years wear out of this one as I did my first and recommend it strongly to anybody who likes winter sports or just comfortable shirts to hang out in during cooler seasons.

My daughter used this a few times this fall during some cold weather softball tournaments. She said it kept her warm. Wasn ’ t restricting during pitching or batting.

I also use it as a first layer when walking my dog in the cool mornings. The extended sleeves with thumb holes are a nice addition and really help to keep my hands warm.
