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.
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.
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.
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 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.
Crafts cool mesh super light baselayer is a life saver on those hot, humid 90p,us degrees days. Effectively wicks the heat away from your core and keeps you from bonking in the heart. Sizing runs small, order a size up.
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.
As per most reviews, the baselayer does run a little big. I am 6'1 208 and pretty big overall and there is some slack in the amount of fabric. Otherwise, the shirt does settle in and helps to wick sweat. Pretty decent quality shirt. I should have bought a few more. I will when they are on sale again.
