Unisex, athletic sizing — runs true, not boxy.

Lift: true to size for a fitted, performance feel.
Run: true to size; size up for a more relaxed, breathable fit.
Ruck: size up one if you're layering or running with a loaded pack.
Trail: true to size for most efforts; size up for extra range of motion on long days.

Still between sizes? Size up.
