This is a half pad by ACAVALLO, a composite type made of gel and memory foam (urethane). There is slight fading from indoor storage, but it has been used very few times and is overall in near-new condition. There is no deterioration in the functionality (gel/memory foam), and I think it's a great deal for those who prioritize practicality. ・No cracks or hardening of the gel ・No compression of the memory foam ・No damage that would interfere with normal use This is a Close Contact series, with a narrower center section that conforms more closely to the horse's back. It's a half pad that combines memory foam (low-resilience urethane) with gel. It has excellent shock absorption and disperses pressure on the horse's back. The gel has unique slits that fit without hindering the horse's movement, and at the same time, it enhances the stability of the saddle, eliminating the need to layer multiple pads. It fits the back well and is a model with an excellent balance of shock absorption and stability. *Please note that this is a used item, so please understand that there may be minor signs of use. The size chart is for reference only. I hope to pass it on to someone who needs it.
