Men's Seamless Sleeveless Base Layer

To sleeve or not to sleeve—that is the question. Sure, it all boils down to a matter of preference, but the objective remains the same for any cycling base layer: increase comfort and maintain a consistent body temperature. And while others might try, nothing delivers like our Seamless Sleeveless Base Layer.
The science behind it is pretty simple. The synthetic yarns pull moisture away from the skin and distributes it across a large surface area where it can be rapidly evaporated. So when you think about it, no moisture buildup means that you won't experience any clammy chills as a result of dramatic temperature swings, and your skin, jersey, and jacket are going to remain dry in order to leave you comfortable.
And furthering this, it features a seamless construction that increases comfort by eliminating seam-induced chafing throughout the base layer. This occurs by eliminating points where the materials could possibly bunch, while the design also creates the added benefit of a next-to-skin level of fit that benefits both comfort and moisture wicking. We also furthered this concept by incorporating targeted ventilation zones throughout the base layer, as well as a cycling-specific cut and targeted stretch that creates the proper "push-pull" for the movements of cycling. It's comfort taken to another level.

Tool was exactly how described and packaging was nice. It did take a few days to ship so unfortunately I didn’t receive it in time for the trip I ordered it for which is the reason for 3 stars but I received it the week after and it’s coming in handy.
size is big enough and clear simple layout. moved from garmin 850. I am very satisfied with wahoo!
Sierra is no joke, this is our 4th bike in the last 3 months and the process has been so easy, they are fair with pricing and never make it feel transactional! I won't be buying anywhere else!
