  • Waterproof polyester — what the rating covers and does not: The SKB-335's polyester shell uses a waterproof coating (typically PU or TPU laminate) that repels light to moderate rain and road splash. This is a surface treatment, not a sealed construction — zippers are not waterproof, and seams are not taped. In sustained heavy rain, water can ingress at zipper tracks and stitching. For wet touring, use a rain cover over the bag or pack valuables (electronics, documents) in a dry bag inside the main compartment. The coating depletes with UV exposure and washing — reapply fabric waterproofing spray annually.
  • Air-cushion back panel — load distribution and a ventilation trade-off: The air-cushion panel creates a stand-off between the bag and the rider's back, distributing load across the shoulder blades and lumbar zone rather than concentrating it at a single contact point. This meaningfully reduces back fatigue on rides over 1–2 hours with a loaded bag. The trade-off is reduced ventilation versus a channel-frame back panel — at low speeds and in hot weather, the air pocket retains heat against the back. At highway speeds, airflow around the bag limits this effect.
  • Two-way back zipper — access angle and riding posture: The back-panel zipper opens from both the top-left and top-right corners, allowing the rider to partially unzip from either side and retrieve items without fully opening the bag. This is particularly useful when the bag is on the back — reaching around to one side to partially open is less awkward than reaching to a single fixed zipper pull. The back-panel opening also provides an anti-theft benefit: the zipper is against the rider's back and not accessible to a bystander when the bag is worn.
  • Helmet capacity — what fits at 50×36×20cm: At these dimensions, the main compartment accommodates most full-face helmets up to approximately size XL. A full-face helmet occupies roughly 35×30×25cm — the bag's 20cm depth is the constraining dimension; confirm your helmet's depth before ordering if purchasing specifically for helmet storage. The remaining space after a helmet is packed can hold a thin jacket layer, gloves, documents, and a water bottle. The 36cm width also accommodates most open-face and modular helmets with room to spare.
  • Reflective logo — passive visibility, not high-visibility standard: The SKB-335 includes retroreflective brand logo strips on the bag exterior. These return vehicle headlight beams toward the source at night — improving rear visibility to following traffic when the bag is worn. This is a supplementary passive feature, not an EN ISO 20471 high-visibility certification. Keep the reflective panels clean for full retroreflective performance.
Key features
01
Air-cushion back panel
Stand-off air-cushion distributes load across the shoulder blades and lumbar zone — reduces spinal pressure on long rides. Not a ventilated channel frame; at low speeds in heat, the panel retains warmth against the back. Most effective above 60km/h where airflow limits heat build-up.
02
Adjustable buckle straps
Shoulder and sternum buckle system allows independent adjustment for torso length and chest width — keeps the bag from shifting laterally during cornering. Set straps with the bag fully loaded in riding posture; a setting made standing will often be too loose on the bike.
03
Two-way back zipper
Opens from both corners of the back panel — partial access from either side without fully unzipping. The back-panel position keeps the zipper pull against the rider's body when worn, reducing opportunistic access by bystanders.
04
Double exterior pockets
Front and side exterior zip pockets provide quick-access storage for phone, keys, cards, and tools without opening the main compartment. Use the front pocket for frequently accessed items and the side pocket for items needed less often — reducing how often the main compartment is exposed in rain.
05
Built-in mesh inner bag
A separate mesh pocket inside the main compartment keeps small items from sinking to the bottom — cables, ear plugs, documents, and cards remain visible and accessible without unpacking the main load. Mesh allows visual identification of contents without opening the inner bag.
06
Reflective logo panels
Retroreflective brand logo strips on the rear face return vehicle headlights toward following traffic at night. Supplementary passive visibility — not EN ISO 20471 rated. Clean reflective panels after wet or muddy rides to maintain retroreflective performance.
