I've been thinking about getting Castelli base layer for a while now and finally got one. Bike tires direct had them on sale for black friday, so I got one.

I've been gradually replacing my Pearl Izumi bike gear with Castellie stuff as things go on sale at BTD. I honestly didn't think the fit of Castellie base layer would be drastically different, but the honest truth is, it's much better fit. The first different is the collar of Castellie is higher than PI transfer baselayer. It's not a turtleneck. It's kind of like a mock/short turtleneck collar. The end result is it keeps makes me feel warmer.
The thing I like most over PI is the fit. Castelli has more compression, which fakes my body into feeling warmer. The second thing I like is the small has shorter sleeves than PI small, so I don't have a bunch of fabric bunched up above my wrist. I'm a short stumpy guy with short arms, so little things like this are quite nice.
