UltrAspire Hydration Race Pack: Alpha 5.0

The latest upgrade to UltrAspire's best selling hydration pack, the 6 litre capacity Alpha 5.0 race vest now has 9 storage pockets that are all accessible on the go. Updated magnet positioning on the rear passage pocket provides more capacity for larger items. The passage pocket has been updated to a nylon polyurethane coated fabric which keeps its contents dry. The stretch-mesh rear passage pocket with magnetic auto-closure can be accessed with either hand, perfect for a grabbing a headlamp or jacket whilst on the move. Updates to the side zipper pockets allow for easier access. In addition, side pockets are now double-layered, adding a quick stash slide-pocket underneath both zippered pockets. The front harness has two large bottle pockets, now taller to allow for a wider variety of bottle options. The pocket mesh has also been updated to a powernet mesh which gives more stretch and added durability. The overall body mesh has been updated to the UltrAcool Light Mesh that dissipates heat quickly. New cord locks on the Z-pole rear attachments allow for easier stash and retrieval of trekking poles or a jacket. Available in three sizes.

Building on the ErgoFit vest design and expanding on successes of the fourth iteration, the UltrAspire Alpha 5.0 race pack focuses on past design strengths while introducing new functional changes. The award-winning Alpha series is the pinnacle of design, functionality, and comfort.

Human shoulders aren’t straight, so a pack’s shoulder straps shouldn’t be either. Longer straps allow the back portion to sit deeper on the neck to prevent any rubbing. This addition in length helps to create slope as the straps come over the top of the shoulders and around the neck following the natural curve of the body. The harness then follows an S curve around the arms and chest area to avoid any hindrance to the running motion.

The harness construction also helps to keep the pack balanced at any capacity to ensure the same high quality fit empty or fully loaded. In regards to balance, the load is positioned lower on the back closer to the body’s center of gravity, the hips. This placement helps to stop unnecessary energy expenditure during the long haul.

A collection of technologies designed to dissipate heat and keep you cool. This system allows you to maintain a lower body temperature by dispersing heat during intense activity, keeping you performing at the highest level.

Anatomically engineered, the pack covers only what is necessary on the body to keep it secure thus allowing for your temperature to remain cooler during heavy energy exertion.

The most breathable mesh on the market, this 3-layered, large holed honeycomb mesh is made from polyester which helps to draw moisture away from the skin without absorption.

Made of Mylar, the insulated compartment reflects and traps temperatures to help keep fluids hot or cold. Additional foam with air pockets creates more space for the insulation to take effect.

Shock cord securing system that helps create a comfortable & natural breathing pattern while at the same time keeping the pack secure. The shock cord allows for stretch outward and 100% rebound which keeps the pack snug against your body empty or fully loaded with no restriction of movement.
