An evolution of the successful RACE ULTRA PRO 2IN1, the new ULTRAPAC PRO 2IN1 boasts greater comfort over longer distances and improved ease of access to kit.

Featuring incredible versatility, this two-in-one pack has a 7-litre compartment that can be attached or removed depending on how much kit you wish to carry. That means you can use it as either a stripped-back 5-litre race vest for shorter runs or, with the compartment attached, as a larger 12-litre pack to carry more kit on ultramarathons or longer runs. 

Includes 2 x 500ml SOFT FLASKS with dual storage options and two easily accessible pole attachment choices. All main materials contain recycled content.


  • THE ULTIMATE IN COMFORT – A new, innovative interior design features zoned areas of stretch that allow the pack to mould and stretch with the upper body as you breathe and run. Feels like a perfectly fitting extra layer rather than a pack.
  • STORAGE VERSATILITY – Featuring a new, easy to use, four-point attachment system, the 7-litre compartment can be quickly added or removed to the back of the pack. This means it can be used as either a stripped-back 5-litre race vest or a larger 12-litre pack.
  • QUICK ACCESS TO KIT – Kit and essentials stored within large stash pockets on either side of the pack or in the multiple front pockets can be accessed quickly. The 7-litre compartment includes a new full-length zip making it quicker and easier to find all kit stored within.
  • DUAL BOTTLE OPTIONS – The 2 x 500ml SOFT FLASKS with detachable 10-inch tubes can be stored in pockets on the side of the body our vertically on the chest. This unique dual option allows you to adapt the pack’s storage to your needs.
  • POLE ATTACHMENT VERSATILITY – A unique back pole attachment system and alternative vertical front pole attachment system make it easy to store and remove poles while on the go. Both systems hold the poles securely with zero-bounce.
  • MORE RESPONSIBLE – All the main materials contain recycled content.
