Momentum 2.0 Race Vest

Built for competitive trail and ultra runners who need to move fast and stay fueled, the Momentum 2.0 is our top pick in a slim, race-ready vest. ErgoFit construction and a 2/3–1/3 waist weight distribution keep the load stable on technical terrain, while the Max02 sternum system lets you breathe freely at full effort. Carries up to four 550mL flasks with everything accessible on the move.

• ErgoFit harness conforms to body contours for precise contact and unrestricted biomechanics — no bouncing, no chafing at race pace
• UltraCool flex mono mesh keeps the vest light and breathable through long efforts in heat and humidity without sacrificing durability
• 2/3–1/3 waist pocket weight ratio lowers your center of gravity and stabilizes the load on technical or uneven terrain
• Max02 shock-cord sternum strap stretches and rebounds 100% — stays snug whether loaded or empty, never restricts your breathing
• Race Line construction in two sizes (Small and Medium available in Black/Red) with capacity for up to four 550mL UltraFlasks (sold separately)
