Ozone Proton
# Ozone Proton

The Ozone Proton is a French single-place paraglider that was designed by hang gliding and paragliding world champion pilot Robbie Whittall and produced by Ozone Gliders of Le Bar-sur-Loup. It is no longer in production.

## Design and development

The Proton was designed as a competition glider. The initial version was later replaced by the Proton GT in production. The GT incorporated a partially closed leading edge, with 20 partially closed and 10 cells fully closed. The models are each named for their relative size.

## Operational history

Reviewer Noel Bertrand described the Ozone series of gliders in a 2003 review as, "wings that are both pleasant to fly and high performance in their respective categories".
