Bought this in yellow - but yellow is not listed anymore.
+ very breathable, less sweating
+ no huge cutout under the arms
+ thin fabric, feels thinner than the t-shirts
o fit is a little tighter, just as described
o Made in China
o price is fair, most singlets are more expensive
o can be worn for about 2 runs before washing (there's worse and better)
- nothing
Conclusion: Glad I bought several.
