the main reason i got this was not because its designed to help you stay cool on hot days, but because on hot days i wear a Le Col Pro Air Nexus jersey which is basically a see thru mesh jersey. great for staying cool, but it leaves nothing to the imagination. adding this base layer allows for the benifit of breathablity while also making my jersy top less see through.
its super light and comfortable and i dont notice its even under my jersey which is a plus.
overall im happy with it.
This was a Daily Special, Looked like a great option for the hot days, but sounded kind of contradictory to wear additional layer on a hot day. I read the reviews and they were good. The price was good when offered for the daily deal. So I purchased the Crafts cool mesh base layer to try and I can say wow I am impressed it works great under your bike shirts they do not stick to you and the holes in fabric let your skin breath. I was so impressed I purchased another one when it was a daily deal again. Now on some cooler mornings about 70 degrees it adds a little warmth. I will buy one more when a deal again. It works great but the little bit of cloth is a lot of money for the full price.
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 can't tell if I need this thing. I've worn this and another Craft baselayer ten or so times in the heat, and on some days it has made me too hot, and on others it seemed to make me sweat more, and the sweat soaked the baselayer, which helped cool me down, but it feels like I'm dehydrated faster. On other days, I feel cool and this thing seems to work. The effect is different with different jerseys. Was I too hot without this baselayer? I don't think so. Best utility is for shoulder seasons, I think.
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.
Have used a warm-weather baselayer for a few years, Craft was the first brand I tried. The sale price made it a no-brainer I needed replacement. White does show some sweat stains (although not until several months of wearing it 2-3 times/week) so also bought a black one this time.
One of my favorite baselayers. Perfect for 65f-80f temp range or so. Great indoors too on the trainer - keeps you cooler than a jersey. Although, mesh feels a little delicate, and requires some care pulling it on and taking off especially when sweaty, after a season of usage no rips or pulls and is still going strong. 38 chest 160lbs I sized down to a SM for a form fit - M felt a little loose for a base.
