ORTLIEB Saddle-Bag High-Vis 4.1 L

The Ortlieb Saddle-Bag High-Vis 4.1 L is designed for cyclists who don't call it a day when the weather turns or the light fades. Its PU-coated nylon fabric with woven reflective thread (PVC-free) provides passive visibility — the reflective elements catch car headlights and street lighting without any electronics involved. Waterproofing is rated at IP64, meaning the bag resists both dust ingress and water spray from any direction. The roll-top closure, secured with side clips, creates a tight seal that holds up through sustained rain or trail riding in wet conditions. Your essentials stay where they should: dry and accessible. Mounting is straightforward: the included kit uses an adjustable snap buckle and velcro strap compatible with seatpost diameters up to 34.9 mm. A built-in attachment loop lets you clip on a rear safety light (sold separately) for added visibility at night. Note that this bag is not compatible with carbon seatposts or saddles. At just 290 g and measuring 14 × 21 × 28 cm, the 4.1 L capacity strikes a practical balance between size and storage. It's manufactured in Heilsbronn, Germany, and comes with a 5-year warranty against material and manufacturing defects.
