Q on "Ultra-Soft®" Gel Saddle Pads

Does anyone know of these pads?

I have an ancient saddle pad with gel pad inserts bought for a western saddle probably 30 years ago. The saddle pad itself is quilted fabric, shaped, and has 2 “pockets” on either side where you insert a blue gel pad. The coating on the pad is degrading and crumbling and I fear is on its last legs.

I have use for this pad now and was wondering if anyone know of anything similar?

Edited to add that since I originally posted, I found these links
