Durable Donut Wing
Delivering industry-leading abrasion resistance that's great for cave diving, the S-Tek Donut Wing's outer shell is made from durable, performance-oriented 1000D Cordura fabric, while the inner bladder is made from 500D Cordura.

Additionally, the wing's rounded profile reduces air trapping, helping ensure smooth, controlled air migration.

Smooth, Balanced Tek BPI
The S-Tek Donut Wing includes the Tek BPI (Balanced Power Inflator) with a K-style layout, providing an extremely robust, lightweight design for smooth, balanced air control during inflation and deflation.

It features an easy-to-control balanced inflation button, a rotating soft mouthpiece for comfortable oral inflation, and an ergonomic design.
