Castelli Airco Base layer.
I bought this for those inbetween chilly and cold days when you can't quite figure out what to wear. This under a jersey, or skinsuit totally blocks out the wind. Great for CX racing, or chilly road rides. Note: these run small as does most Castelli stuff.
Great fit and has worked great on chilly weather morning rides for me. I haven't used it in the winter yet but I definitely plan to. I went with short sleeves over long because I don't mind wearing arm warmers with it. I'm 6ft tall and about 160 and the small/med size fit very tight but I wanted that under armour type compression feel. The sleeves are form fitting enough that they don't bunch up under my race fit jerseys.
I wish I had one for every day of the week
This base layer is perfect. I'm 6' 190 lbs and the xxl fits perfect. I ride a fixed gear and can work up quite a sweat, but this base wicks it away almost immediately and keeps me warm when paired with my gore jacket in 20 degree weather.
better than underarmor with its cyclist's fit
as for me, i'm 5'8", 145lbs, and the s/m size fit nicely. this shirt is body-hugging, but not tight or restrictive as it stretches well (without stretching out). the material is 82% nylon, 18% polyester, and the inside is soft with a nice feel to the skin. i have only worn this around town and to try on with some cycling gear, but can tell that it will be a great layering piece for any season spring to fall, under short-sleeve or long.
i bought this on bonktown for a deal and would recommend it it you can find it there but wouldn't pay msrp otherwise. so, here's five stars for the base layer at the price i paid.
