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.
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.
Underlayer for biking in the hot weather. Haven't had a chance to try yet but replacing a layer I have used in the past and look forward to comparing them.
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.
Ultra light baselayer. Though advertised for use on the hottest days, I tend to use this weight on days that are just a bit cooler than I'd be comfortable with just a jersey. It adds just enough warmth to take away that early-ride chill without being too hot as the day warms up. I've been very happy with Craft products - I have several base layers of different weights. They are some of my favorite riding clothes.
It's still too early to tell if this will fall apart over time. I plan on using it weekly as I did with my Pearl Izumi baselayer and so far it's lasted me 3 years with no issues. So I will compare it to my PI. It's very light, and comfy, keeps me cool in the Florida hot and humid weather. I don't feel sticky at the end of my rides and still able to not feel overheated. I bought a size medium, which I usually wear, but appears to be more loose. Maybe next time I'll order a small and see if it'll fit well. Anyway, like I said earlier my review might change over time since I'm going to compare it to my PI that I've been using for over 3 years and so far nothing wrong with it.
Used under jersey in all weather conditions. Keeps a layer of ventilation when it's hot out allowing cooler air layer between skin and jersey, jersey doesn't stick to the skin.
I like this baselayer a lot and I use it to put a little moisture wicking between me and lycra, works well, even when it's pretty hot. I'm about 5'9160 (175cm72kg) and it fits fine.
