The shirt is extremely light weight, feels great to wear, and I've found that it keeps me warm on some pretty cold (15 F) early morning walks. I bought it in xl since it said it had a slim fit. While the body and shoulders fit great, I found that the sleeves run a bit long, but if you're wearing it under a sweater or shirt, not really a problem. As for washing, just to stay safe and maintain the breathability of the fabric, I've gone the handwashing route. All in all, highly reccomend this
"Will not end up cold or soaked with sweat"
I exercise race horses in the Chicago area. That means I'm outside going 30 mph at 6 am not matter what the weather. The thing is its hard work and while walking to and from the barn is cold while I'm riding it is quite the workout. Which means I end up a) cold from not enough clothes or b) cold because I was drenched with sweat after each horse. Capilene has been my savior! I tried one and now ordered 5! Size tip: I'm a 5'4" 120 lbs female but like the shirts a bit loose and long enough to stay down belowdecks jacket despite the action of riding. A men's small works great because the women's small is too short and the women's medium is too big
