Ideal for road cyclists, trekkers and triathletes who want compact under-saddle storage for a tube, tyre levers and essential tools.
The ZEFAL Z Light Pack S is a compact saddle bag for road cycling, trekking and triathlon. With 0.5 L of storage and a lightweight 58 g construction, it gives you a practical place to carry the essentials without filling your jersey pockets or weighing down the bike. The published storage layout accommodates one inner tube, two tyre levers and a multi-tool, or an inner tube, tyre levers and a CO₂ inflator such as the EZ Big Shot.
It mounts beneath the saddle using self-gripping straps that fit all standard saddle rails, making installation quick and straightforward. The 420D Ripstop polyester construction is designed to stay light while providing useful everyday durability, and the water-repellent zip helps protect your spares and tools from road spray and light moisture. For care, hand washing is recommended; do not machine wash the bag.
Reflective strips improve visibility in low light, while the integrated light mount gives you a convenient place to add a rear light for night rides. Measuring 14.00 x 6.50 x 7.00 cm, the Z Light Pack S is a sensible choice when you want reliable puncture-repair storage in a tidy, unobtrusive package.
