I just looked on the Wintec Website
www.wintec.net.au and it had the following to say on CAIR:
CAIR air panels hold their shape unlike traditional stuffing which will, over time, ride down and become unevenly compacted.
CAIR air panels do not need adjustment or special maintenance and require no re-stuffing.
CAIR air panels constantly adapt to your horse's shape as the back and shoulder muscles work.
and had this to say about their ordinary saddles:
In order to keep the saddle fitting well, you should have the fit of your Wintec saddle checked after 4 to 6 weeks of riding to ensure sufficient clearance is still being provided to the horse's wither.
We recommend riders check the fit of their saddles after 3 months and then every 6 months throughout their saddles life, to ensure the saddle continues to fit correctly as the horse changes shape according to its level of fitness.
If the saddle comes too close to the wither, the panel should be inspected to see whether the best alternative is to either add more wool to the front of the saddle or fit a slightly narrower gullet plate. In general we would advise the fitting of a narrow gullet plate, providing there is still ample resilience and depth in the wool panel, so the closest fit to the horse's back is maintained.
When the saddles are restuffed, care should be taken not to over-stuff the panels as in most cases this will cause an incorrect fit on the horse and improper weight distribution. It is a far better alternative to fill the panel back to approximately its original stuffed shape and lift the front of the saddle through the fitting of one of our fractional fit gullets as required.
Through the use of the Easy Change Gullet System and Wool Repacking a Wintec saddle can be custom fitted to your horse's back. Wintec recommend that a qualified saddle fitter is consulted when buying and fitting a new saddle.
Hope this helps.
