- Familiarity: I've used it once or twice and have initial impressions
- Fit: Runs small
- Size Bought: Large
I have a variety of Castelli tops. They run small, so I always know a Large will fit me snug. This one fits really snug but not tight. Almost like a second skin. I have worn it twice in 60-70 degree temps. At 60 degrees it gets a little chilly. I really like this one. Should work well this summer.
