ThighPro Locked In Mock Neck Short Sleeve Compression Shirt

After three summer ball games in 90+ degree heat, the Locked In Mock is my new favorite undershirt. Its moisture management blows the doors off the Patagonia tech tees I usually wear that end up a sweat-soaked mess by the time I walked off the field. (And yes, I walked onto the field properly hydrated.) The Locked In Mock is a true compression garment. The fit is superhero snug and I think that's what makes all the difference in terms of moisture management. And this might just be psychological, but it feels like my chest protector fits better while wearing it since there isn't a loose t-shirt sliding around underneath. The look is stylish (and has me feeling a bit like Ichiro). Before next season, I'll get a white one to go with my black so those partners who specify undershirt color can see I got their memo. Finally, the collar's gentle firmness around the neck is a subtle reminder that baseball moms will be ready to strangle you if you don't lock in.

Very good undershirt. Fits well, good quality. I like that the logo is subdued.
