Out of Arc'teryx's entire collection of trail running tees, the Men's Motus Comp Shirt is certainly one of the more technical options to better prepare you for race day. It's made out of the same airy, breathable, and light Reza mesh fabric as the original Arc'teryx Motus, except Phasic FL fabric covers the shoulders for better durability against hydration packs. Arc'teryx also minimized the seams as much as possible to reduce irritation on long competitions.
