Best performance shirt around

Trevor V. · 2025-09-09 · Verified purchase

I've tried many performance shirts, and this one truly stands out. The high-stretch fabric is incredible for mobility, and the bonded seams mean absolutely no chafing during long workouts.

★★☆☆☆

Too tight in the arms

Tyler K. · 2025-08-25 · Verified purchase

Ordered my usual size M in Navy and found the arms uncomfortably tight, restricting movement. The overall streamlined fit is a little too snug for me.

★★★★☆

Solid training shirt

Max P. · 2025-11-03 · Verified purchase

Got the OD Green in a size L, and it generally fits well for a streamlined cut. The fabric performs great under heavy sweating, but the neck opening feels a little snug when pulling it on.

★★★★★

Feels like nothing is there

Greg R. · 2026-01-30 · Verified purchase

The fabric is so light, it practically disappears during my runs.

★★★★☆

Comfortable, minor issue

Mitch J. · 2025-12-26 · Verified purchase

Very comfortable for workouts, but the length could be a bit shorter for my preference.
