Overview

The Ultraspire Alpha Race Vest is a lightweight, unisex hydration solution designed to move with you from start line to finish. Built for speed and endurance, it emphasizes a precise fit, balanced weight, and temperature-aware materials. The 5.0 blue colorway adds a modern, high-visibility touch on the trail.

ErgoFit and movement

ErgoFit mirrors the body's natural shape so the pack stays unobtrusive as you bend, stride, or sprint. The goal is fluid movement with even weight distribution, helping you stay focused on rhythm rather than gear.

• ErgoFit provides precise movement and balanced weight without hindering biomechanics.
• Longer shoulder straps keep the back aligned with the neck’s natural curve to reduce rubbing.

Insulated bladder compartment and temperature control

The insulated bladder compartment, lined with Mylar, reflects and traps temperature to help fluids stay within your preferred range as you move through varying conditions.

• Shoulder straps and the insulated bladder compartment help keep fluids at the right temperature and reduce chafing.
• Mylar insulation maintains temperature for hot or cold beverages during long sessions.

UltraCool system and breathability

During exertion, heat can impact comfort. The UltraCool system disperses heat to maintain a more comfortable feel, letting you focus on the task ahead. A breathable, 3-layer mesh back panel supports airflow and moisture management.

• UltraCool system helps manage heat during intense activity for steadier comfort.
• Large-holed mesh pulls moisture away from the skin and dries quickly for a cooler ride.

Secure fit and breathing with MAX02 sternum

The MAX02 sternum restraint uses a shock cord that stretches outward and rebounds for a snug, secure fit while preserving natural breathing whether the vest is empty or loaded.

• MAX02 sternum secure system enhances stability without restricting breathing.
• The design adapts to movement, maintaining contact without discomfort.

Real-world use and benefits

Runners, hikers, and endurance athletes can enjoy hands-free hydration, quick access to essentials, and a minimalist silhouette that stays with you on varied terrain. The combination of fit, temperature control, and ventilation supports longer sessions in a range of conditions.

• Lightweight, secure, and breathable for long runs and trail outings.
• Temperature-aware materials help keep beverages accessible across climates.
