Very lightweight, buy a size down if you are use to a Euro race fit...I usually wear a size large in euro tops, xlarge in Castelli baselayers, but a medium fit the bill here...the fabric is so stretchy and comfortable I probably could have fit the small...We had a two week hot and humid streak here in NYC and this performed admirably in providing a cooling effect on the bike...I bought a white and black one on sale with what I think was a 30% discount...A Win Win all the way around...
I've been using it as a base layer for cold riding under a castelli convertible gabba jacket/jersey. It works great! I'm comfortable through out the ride. It wicks very well and feels dry at the end of the ride. I am going to try it in the summer under a jersey, but I'm reluctant to believe that any base layer can be cooling.
I'm 165 and 5'-10" and bought the medium. Perfect fit all around and very breathable. Works great under short sleeve jerseys on warmer days to stay cool, and under long sleeves for just a bit of extra warmth to take the chill off.
Cycling clothing is so expensive. I'm getting older now and wanted to get into base layer clothing. I was skeptical of this product due to the low price but was pleasantly surprised. Fit and quality are top notch and it works as advertised. satisfied customer.
I had never worn base layers except in cold weather, but after seeing many pros wear mesh base layers in hot weather, I decided to give this a try.
I wish I had tried these a long time ago. Using one under bibshorts is much more comfortable - no more chafing from the straps, cooler in hot weather (as long as you're not wearing a tight black jersey), and warmer in cool weather.
I now own several of these and they've survived many dozens of washes with no adverse effects.
I hardly ever do casual rides, I get on the bike, warm up and crank. I have two craft mesh base layers and I swear by them. They keep me dry and comfortable by wicking my perspiration away from me. When I finish my rides I can't believe how wet my jerseys are when I take them off.
This mesh baselayer helps on a hot day. It keeps some flow circulating under your jersey. I like a snug fit for a baselayer, which opens up the gaps in the mesh, and find this runs large. I normally wear a large jersey and found a medium was the best fit.
