For aquatic environments or actual flying, vulcanised natural rubber guarantees resilience. Heavy canvas NATO straps remain historically the most reliable solution for aviators.

The strap is secured via two springbar pins, one on each lug. Use a springbar tool to compress the internal mechanism and slide the pin out of its seat. Repeat for the other lug. Insert the new strap by aligning the terminal holes with the pins, then release for securing. Operation takes 3-4 minutes with the proper tool.

A vegetable-tanned leather strap, with proper maintenance, guarantees 5-8 years of daily wear. Longevity depends on humidity exposure, climate conditions and frequency of use. Leather develops natural patina, enhancing its aesthetic appeal over time. Protect from excessive moisture and occasionally apply balms specific to noble leathers.
