love it!
no itch at all. Perfect warmth. I usually sweat easily. wore it on a warmer day with a cami under and a shell jacket on top; wore it on a colder day with another long sleeve layer with the jacket on top and was perfect both days.

This is now my all time favorite cool, damp weather bike jersey. It fits close enough not to flap, doesn't stink when sweaty, and doesn't itch.
Short zipper can be adjusted to let out excess heat, or zipped up for more warmth.

I love this top! The fit is great- I have a Large, as I have a very broad torso and it does not constrict at all. The wool is as soft as can be so there is no scratchiness at all. I tend to get warm on runs, even on the coldest days and if I peel off the jacket, I am perfectly fine in this. I almost exclusively wear smart wool socks and will now start converting all my winter running gear to merino wool.

this shirt is a staple for me. I now have 3. I love it for running, I can just tie it on my waist once i heat up and it is super lightweight. the 1/4 zip is great for dumping heat when i start to warm up. great for those cool early morning runs

The minute I put it on I could tell I'd be wearing it a ton this winter. It's super comfy and ridiculously soft. It's not as warm as I was hoping or thinking it would be, but it's an excellent base layer.
It's also really cute. I got the black one and it actually looks good by itself- not like a base layer.

True to size, but close fitting as
a base layer should be. I got
a medium to make sure it would go over my workout tops without any
lumps showing (normally I would wear a small). So far it fits just right, keeps me perfectly comfortable in spring/summer temps (it is nice protection against rain & over-air-conditioned spaces) and dont be fooled by the lightweight fabric - it is sturdy and well made. On a typical day I might scrape up against
muddy, moss-covered rocks in the pouring rain, then
after a light brushoff, I wear it - proudly - out for beers or coffee.

I'm always cold...always. So, I love how warm wool is, but I definitely do not like the itch factor...enter Icebreaker merino wool. It's amazing stuff. It's warm, it's soft, and it rarely smells. The green color is adorable and I would guess the 1/4 zip is great if you get a little too warm.

First of all, I have to say I am a sucker for the 1/4 zip tops. Love them. I have fleece ones, lightweight capilene ones, midweight capilene ones, etc...I decided I needed to try out the merino wool variety and settled on Icebreaker. This piece is great. The fit is amazing, fitted without being restrictive and the wool is so soft and smooth! I didn't give it five stars because despite all of the claims of being stink-free, after a day of snowboarding it definitely needed to be washed. Maybe I'm just stinky or the softshell I had over it kept my sweat from evaporating fast enough or maybe the synthetic shirt I had underneath was to blame...whatever the reason, it still stank. Maybe I'll try it on its own this weekend and see how that goes. I'd still recommend it, but know that you will need to wash it as much as anything else.
