Craft Men's Cool Mesh Superlight Sleeveless Baselayer

I was a bit skeptical about another layer under my aero kit in the heat. But I'm a convert now. The Craft Cool Mesh Superlight Baselayer works just as advertised and referenced in other reviews. The large holes in the fabric enable evaporative cooling when your kit would normally be soaked in sweat and clinging to you. I've been riding in temps in the upper 90's with humidity around 40% without issue, where in summers past the heat would be a factor. I've had a Craft winter baselayer for 20+ years, so I knew Craft meant quality, and this baselayer is no different. "Cool Mesh Superlight" is a perfect name, as you don't even notice you have it on under your kit. I have no way to confirm the claims of a 5 to 6 degree cooler ride, but I definitely feel cooler. For sizing, I'm 6' 2", 165lbs, with a 39" chest. I purchased a medium, which fits perfectly. It is long enough that I have to tuck the bottom inch or so into my shorts, but that's not an issue for me.

These are nice undershirts, especially as many have noted, when on sale which is often. I typically take a XL in Rapha jerseys and a L in Ornot and most other brands. I originally followed the sizing chart on these, but they are huge and they stretch a ton. I started with 2 XL's (shoulders way too wide), and then 2 L's (also way wide), and finally one M - perfect. Wish it hadn't taken 4 oversized ones to figure out the right sizing - feels wasteful and seriously inaccurate for the size chart.

The material and product is great though, just know they run incredibly over-sized as indicated.

Based on my comparison of other products and other sellers, this was being offered at a great price, so I took a chance with it. It's well-made, looks to have good craftsmanship. The fit is a little bit on the long side, but snug-ness is good: not compression-level, but close-fitting, which is what I was expecting. I have to fold it back up at the bottom as it's longer than my jersey. Does it actually work to cool by air-flow under the jersey? To be honest, I can't really tell. It doesn't make things hotter, which would be the opposite effect. But do I feel more air flow? I'd have to ride a bit with it and then ride a bit without it for a back-to-back comparison. Unlike the other reviewers, my skin must be less sensitive to feeling these things. Otherwise, it's a well-made base layer and worth your consideration if you're in the market for one.

There are a couple of different fabric available for Craft base layers but this one is the lightest and best for intense riding in warm conditions. Lays flat on the skin, looks good, and has superior wicking. Will buy more. 5 star value if on sale.

Awesome Craft quality at bonus Daily Special pricing. THX BTD!!

works well to regulate temp

I have no empirical data but it doesn't feel any cooler. I did not measure with a thermometer and am purely going based off vibes so take this review for what it's worth. However, I wouldn't order it again and do not wear it on a majority of rides.

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.

This base layer is lightweight, feels good against your skin, and helps wick sweat. I've got a few of them, dark and light, that I rotate through to wear on almost every ride. Summer they are great and I even like to wear them in cooler weather to stay more dry if you are riding hard. When on sale, they are a solid value and last well.

I've ridden these a lot on rides where the temp goes well over 100'. Keeps you cooler than just a jersey, that's for sure. You wouldn't think they would but they do. You don't even notice that it's there except that you're cooler than without it. If I had to make a complaint, it's that sunscreen stains the neck after a while. But nobody ever sees these when you're riding so who cares, right? They go on sale every so often so keep an eye out.

I was skeptical at first, but having a mesh base layer on during high summer temps helped keep me significantly cooler vs a jersey alone.

This things last forever. True to size. Great quality.

I ALWAYS wear a base layer!

Great base layer for spring, summer and fall.

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.

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'm 67 inches tall, 140lbs, with a short torso, and the small is much too large for a base-layer intended to be form-fitting. They also stretch, making the situation worse. I have 3 of these, and have used them for many years, so this is not a deal breaker, but a suggestion to BTD that they please order the extra-small I see on the Craft website. These are a fair deal, on sale in the 35 dollar range, but overpriced at retail.

This is my third Craft lightweight/summer undershirt. They work great 70-100F, and I swear keep you just that little bit cooler or warmer. I also have a couple of the more insulating unders for cold weather and there is a marked difference in that these do not provide warmth under 50F.

Newbie to bib shorts - rode with jersey above and below bib strap for a year. Read reviews and bought one of these Craft undershirts this spring. Needless to say I am sold on the utility of the undershirt and have since bought a second to add to my rotation. A great addition to those riding bib shorts in warm weather. Medium works great for 6'1" and 175 lb guy.

I hesitantly ordered a size small at 5'9", 150 lbs based on other reviews. The fit is perfect--provides compression without being constrictive or uncomfortable. Have not worn it lately because of the blistering hot temps, but in early summer I did notice it helping my jersey to stay dry, which, I guess, is the whole point. I think it will be very useful this fall as a base layer.
