Men's Sleeveless Cycling Base Layer Bike Undershirt,Breathable,Superlight and Moisture Wicking

Note, if you're looking for a very good wicking hot weather base layer, this is not it. I don't know where all of these reviews are coming from but these are just generic amazon base layers from China. If you want a really quality base layer you're still going to have to pay some money for something ultra-light and super wicking. That said, if it's colder out and not super hot, I would wear these, anything above 75 its just a shirt and can lead to heat rash if you are not careful

I use these for a heavy cycling training and racing regimen. I've now ordered two pairs of these base layers and for the price, I can't imagine how they'd be beaten. I have a more expensive base layer, but these are always my go to. Note, the newer version of these foregoes the tag, which is a welcome change.The fit is as expected, although us serious cyclists have a tendency to view anything other than skin tight as loose, so take that into consideration. I expect a base layer to be tight. I have a 39" chest with a 31" waist and initially tried a Small (again, cyclist here). The mid section and waist were as I preferred, but the top a bit tight. I've since switched to a medium and while I have the occasional ruffling in the mid section, it's a very good fit. These run long, but that's preferable for my use.The unfortunate thing is when someone asks me who makes this base layer, I don't know how to respond... My best attempts have resulted in me simply putting my tongue between my lips and blowing a raspberry. Seriously, there's no other way to say this.

Great value, especially when compared with well known cycling brands! When the temp is between 45 and 55 degrees F., these work great under a regular short sleeve jersey. I use this combo with arm warmers in that temp range and it works great. (If it's colder, I'll go with a long sleeve base layer and long sleeve jersey.)

This is not exactly mesh, but a little more substantial, more like a kind of light waffle weave. The result is that the material wicks sweat away from your skin and keeps you cooler without feeling like your kit is sticking to your skin. I ride anywhere between 80-150 mi/wk, am 6'1" and 230 lbs (not small) and normally wear an xl in most tshirts, however I wear a 2x in these shirts because of their close fit and my feeling is that they run slightly small - not much, just a little. Living in Northern California, I wear these pretty much all year 'round - with arm warmers in the late fall and under a long sleeved or fleeced jersey in the winter. I'm sure that there are other inexpensive base layer shirts out there that do the same thing, but these work perfectly for me, the price is right so I own 5 of them so don't have to wash every other day. Ride safe out there...

So, so frustrating!!! I purchased two of these base layers, materials great, fits great, first wear just awesome! Unfortunately after second wear the collar and/or trimming has yellowed. I've tried washing manually by hand, all types of soap and cannot get the trimming white! I also have one in black and another in blue, clearly those do not show yellowing. But whatever fabric is used for the seams is subject to yellowing.

Awesome quality base layers! I've been wearing these alone while cycling and they're excellent. I'm 6'4" and I have 42-44" chest and a 33-34" waist. I prefer a more fitted shirt so I went with a size Large. The fit is perfect. Not restricting at all but still supportive and very comfortable. The only thing I would like to see available in the future would be a "Tall" version of this. I have a longer torso at 21-22" and a shirt that was another 2-3" longer would make this a seven star product that I would HAVE to buy. Thanks to the folks at Bpbtti for providing an excellent product at an excellent price.P.S. Does anyone know how to pronounce this brand??

I have worn the Bpbtti sleeveless cycling base layer under a technical wicking top layer and also by itself. I love the breathability and now that I've used it for several months on hot/humid and cool/breezy mornings it has become one of my all-time favorites. The fit is true to size and feels a little snug, but this is perfect for cycling. I've washed it over and over, it's been dried it in a drier and drip dried multiple times, and it still fits and feels like the day I got it. This is a great product, and I would definitely recommend it.

I'm a daily, year-around, 30 mile bicycle commuter living in Florida. I like a sleeveless compression base-layer under my cycling tops both summer and winter. These are good, if a little pricy. I've found them to be "true to size" for US sizing, if slightly long (down to crotch level/swell of buttocks), and provide good compression without being "tight". I'm 6' 220lbs, wide shoulders with "bodyguard" build. I've purchased a total of four of these tops. Quality appears to be good. Each has been washed (cold, delicate cycle, no fabric softener) 20+ times and appear to be holding up, though the "printed" label and logos have come off.
