Ultraspire Alpha Hydration Pack for Trail Runners

About this item

• Made in the USA or Imported
• Nylon
• UltraCool System - When the human body exerts force, 80% of the power it generates is converted to thermal energy. This means that most of the energy you use when running, climbing, or doing anything else is lost and becomes heat. The hotter you are, the worse you perform. This system allows you to maintain a lower body temperature by dispersing heat during intense activity, keeping you performing at the highest level.
• **Shoulder Straps and Insulated Bladder Section** - Since human shoulders have a natural curvature, it’s important for a backpack's shoulder straps to be designed accordingly. Extended straps enable the rear part to rest lower on the neck, reducing the risk of chafing. This extra length creates an incline as the straps traverse over the shoulders and encircle the neck, aligning with the body’s natural shape. The insulated section, crafted from Mylar, reflects and retains temperatures, aiding in the maintenance of both hot and cold liquids.
• MAX02 Sternum - The Max02 Sternum is a 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.
• Small Footprint & UltraCool Mesh - 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.
• ErgoFit - The human body is complex with intricate detail and function. The same attention to detail is present in the design of our packs to enable precise movement, contact, and weight distribution which ensures that there is never any inhibition to the biomechanics of the human body.
