• 14 litre capacity: Substantial storage for larger mandatory-kit loads, spare clothing, food, hydration and other ultra-running equipment.
• 2x 800ml Soft Flasks included: Provides 1.6 litres of front hydration, with adjustable bungees helping support the flasks as they empty.
• MaxO2 Form closure: Shock-cord adjustment conforms the vest around the body and load while allowing expansion during breathing.
• Reservoir compatible: Dedicated insulated and padded rear compartment accepts up to a 2 litre reservoir, not included.
• 12 pockets: A mixture of front, side and rear storage provides extensive organisation, with ten pockets accessible while running.
• Front storage: Zipped and open pockets provide separate secure and quick-access storage.
• Side stretch pockets: Large open-top pockets provide accessible space for additional hydration, food or clothing.
• Rear storage: Large clamshell-style zipped compartment includes an internal zipped pocket and key clip.
• External stretch compartment: Provides quick-stash storage without opening the main rear compartment.
• Load compression: Two adjustable rear straps help control the load as the contents change.
• Trekking-pole carry: Rear bungee attachments provide integrated pole storage; the vest is also compatible with the UltrAspire Pole Quiver.
• Water-resistant construction: Silicone and PU-coated lightweight nylon is designed to resist water, abrasion and tearing.
• Breathable mesh: Large-hole mesh helps move moisture away from the body.
• Soft edge binding: Reduces abrasive contact against skin and clothing.
• Safety whistle: Integrated into the front of the vest.

Measure around the chest while wearing the clothing you expect to use with the vest. Allow for the additional bulk of clothing and remember that a fully loaded vest can fit more closely than an empty one.

The MaxO2 Form shock-cord closure provides additional adjustment around the chest and allows the vest to respond to changes in load and breathing.

If you are deciding how much carrying capacity you need, see our Running Backpacks, Race Vests & Hydration Packs Guide. Capacity should be considered alongside mandatory kit, aid-point spacing, weather, pace, access to crew and your preferred carrying strategy, rather than race distance alone.
