Redesigned to provide easier access to your water and gear, the UltraAspire Momentum 2.0 hydration vest is a minimalist race vest with dedicated pockets for water bottles, food, a phone and clothes.


  • Features new pockets that are more intuitive and easier to access thanks to magnetic closures and a rail-like system—you can reach back to grab or stow bottles while on the go
  • Main compartment in back allows you to quickly stash and access gear and clothing on the go
  • UltrAcool Light Mesh provides a very breathable and lightweight feel and increases pack durability
  • ErgoFit™ design enables precise movement, contact and weight distribution to preserve the free motion of your body's biomechanics; low center of gravity boosts pack stability
  • Angled S-curve straps help you move freely while reducing neck and shoulder fatigue
  • Distributed Weight™ helps keep the pack balanced to ensure the same comfortable fit, whether empty or fully loaded
  • Max02™ System shockcord design on the chest allows for comfortable and natural breathing while at the same time keeping the pack secure
  • Durable and lightweight fabrics offer a high strength-to-weight ratio; they're placed in high-contact areas and stress points for maximum abrasion resistance and durability
  • An upgraded shoulder pocket allows you to carry any size cellphone
  • Shockcord on both front strap pockets increases versatility among what gear or bottles you choose to carry
  • Vest can hold up to 4 bottles (bottles not included)
  • Includes trekking pole attachments (poles not included); vest is compatible with Black Diamond Z trekking poles
