Ultraspire Stealth Race Vest – Black Large with 2x 300 ml Softflasks

The Ultraspire Stealth Race Vest is a minimalist hydration solution built for fast-paced race days. It blends feather-light comfort with a secure, close fit that stays out of your way during bursts of speed. The sleek silhouette minimizes bounce and snagging on gear, so you can focus on pacing, terrain, and rhythm.

Lightweight comfort you can feel

Every detail is chosen to support movement without distraction. UltrAcool Light Mesh enhances breathability, while silicone- and PU-coated nylon fabrics resist water, abrasion, and tears for durable performance without bulk. Plush micro-fiber polyester edges feel soft against skin, reducing friction during longer efforts. Sweat-proof webbing helps keep weights manageable even when you push the pace.

• Lightweight, soft, breathable mesh for all-day comfort
• Water- and abrasion-resistant fabrics for race-day reliability
• MaxO2 Form closure supports stable breathing with a secure fit

Smart access, secure storage, and easy hydration

The vest offers seven pockets positioned for quick access and gear prioritization. Magnetic side closures keep contents in place during high-output efforts, while the front harness includes an open mesh pocket and a zippered pocket for small items. The kit includes two 300 ml Softflasks that fit neatly into the main harness pockets, preserving a slim profile on the torso for a streamlined feel.

• Magnetic side pockets secure essentials without extra bulk
• Open mesh and zippered pockets for organization
• Two 300 ml Softflasks ready for on-the-go hydration

Designed for a confident, adjustable fit

The Stealth Race Vest uses the MaxO2 Form adjustable closure system to adapt to your body as the load changes, without compromising breathing. Plush edges, sweat-proof webbing, and zig-zag stitching offer durability while keeping the overall footprint light. Available in three sizes to help you dial in a secure, comfortable fit for a variety of body types.

• MaxO2 Form keeps the pack secure and breathing-friendly
• Soft edges and sweat-proof webbing reduce chafing
