Dry bag Fidlock HERMETIC medi TTT Waterproof 11L — roll-top carry bag, 11 liters capacity

Fidlock HERMETIC medi TTT Waterproof 11L is a roll-top carry bag designed to protect personal items and equipment from water, dust and moisture during outdoor activities. The 11-litre volume offers space for essentials on day trips, cycling, short hikes or boat outings while maintaining a compact profile. The HERMETIC closure system ensures a reliable watertight seal, and the bag's construction uses durable materials to withstand frequent handling and exposure to outdoor conditions.

Advantages

The roll-top design with the HERMETIC sealing system creates a simple, repeatable closure that prevents water ingress when properly closed. The bag's shape and size balance capacity and portability, fitting easily into panniers or stowing on a bike rack. Robust fabric and reinforced seams increase resistance to abrasion and everyday wear. The compact, cylindrical form factor and attachment-friendly exterior allow the bag to integrate with straps, racks or other carrying systems without adding excessive bulk.

Suitable for

• Day trips and commuting where weather protection is required
• Cycling and bikepacking as a handlebar or rack-mounted dry bag
• Short hikes and outdoor activities with moderate gear needs
• Boating, kayaking or waterside use to protect electronics and clothing

How to use

Place items inside the bag without overloading the main compartment, then align the roll-top opening and roll it down at least three times to engage the HERMETIC sealing system. Fold the closure into the locking position according to the visible alignment guides and secure it to ensure a watertight seal. Carry the bag by hand, attach it to a rack or strap it to a bike using compatible mounting points, or stow it inside a larger pack. After use in wet or sandy conditions, rinse exterior surfaces with fresh water and allow the bag to dry fully before storage to maintain material integrity.

Usage recommendations

Do not submerge the bag under prolonged pressure; the HERMETIC system is designed to protect against splashes, rain and temporary immersion but is not a substitute for certified submersible cases. Avoid sharp objects inside the bag that could puncture the lining, and store the bag dry and rolled open when not in use to preserve seals and fabric performance.
