The Cyclite Hydration Vest / 01 revolutionizes cycling hydration with its featherweight of 156 to 176 grams depending on size, while offering a capacity of 4.5 to 5 liters. Designed in the Bavarian Alps by Cyclite, a German brand specializing in ultralight bikepacking equipment, this hydration vest redefines segment standards with its exceptional weight-to-volume ratio and ergonomic athletic fit. Developed specifically for ultra-races, gravel competitions, endurance events and long road rides, it literally disappears on your back thanks to its 4-way stretch nylon polyamide fabric and ultra-breathable 3D mesh lining.

Technical Highlights

• Advanced ultralight construction: At only 156 g in size S/M (176 g in M/L), the vest rivals the lightest solutions on the market while maintaining remarkable durability. 20 denier ripstop fabric in high-density nylon, silicone and polyurethane treated for optimal abrasion and water resistance.
• Cycling-specific ergonomics: The athletic fit and 4-way stretch perfectly conform to upper body morphology without compromising access to jersey back pockets. Ideal for combining autonomous hydration and traditional nutrition.
• Optimized thermal management: The air-permeable 3D mesh ensures continuous ventilation across the entire back, preventing heat accumulation even during high intensity or in hot weather.
• Intelligent hydration system: Main zippered compartment accommodates a hydration bladder up to 2 liters. The tube is held by an innovative magnetic mechanism on the right shoulder strap, allowing effortless drinking while riding. Compatible with all standard hydration bladders on the market.
• Streamlined organization: 6 strategic storage spaces – main compartment for jacket/hydration bladder, 2 side zippered pockets for arm warmers or windbreaker, 3 shoulder strap pockets including one with zipper (left) for smartphone/bars/gels, easily accessible while moving.
• Customizable adjustments: Height and width adjustable chest strap system for a tailored fit, regardless of body type (size compatibility S/M 150-180 cm, M/L 170-200 cm).
• Integrated safety: Reflective elements strategically positioned for twilight/nighttime visibility + rear light mount for additional lighting in low-light conditions.

Materials and Manufacturing

Cyclite uses high-performance technical fabrics developed specifically for the bikepacking segment: 4-way stretch polyamide/nylon knit for the outer shell, 4-way power mesh for stress zones, 3D air mesh for back contact, elastic cords, POM (polyoxymethylene) inserts for rigid attachments. The 20 denier ripstop fabric combines extreme lightness and tear resistance. Assembly by high-frequency welding of main seams for reinforced waterproofing and elimination of weak points associated with traditional stitching. Silicone and PU water-repellent treatment for protection against light weather.

Design Philosophy

Founded in 2020 by Christoph Kirsch and Max Barnsteiner in Grassau (Chiemsee, Bavaria), Cyclite has established itself as a reference for ultralight bikepacking equipment in Europe. The brand applies a holistic approach: each product is designed as a whole rather than assembled from generic components. The Hydration Vest / 01 embodies this philosophy with its custom-developed proprietary fabric, welded seams and ergonomics designed specifically for long-distance cycling. Since 2025, Cyclite exclusively uses recycled nylon and is a member of the "1% for the Planet" initiative.

Recommended Applications

The Cyclite Hydration Vest / 01 excels in disciplines requiring water autonomy and freedom of movement: bikepacking ultra-races (TCR, GBDURO), long-distance gravel rides, road cycling sportives, bike-oriented trail running, alpine MTB tours. Its aerodynamic profile minimizes wind drag on the road, while its compactness preserves agility on single track. Compatible with traditional cycling jerseys thanks to its cut that leaves free access to the three back pockets. Credible alternative to frame-mounted systems for rides requiring significant water volume (>1.5 L) without sacrificing bike handling.
