The Circuit Crash Pad is engineered as a daily workhorse for the cost-conscious boulderer, featuring Black Diamond's closed-cell PE foam layup with EVA bonded together, making it lightweight but solid for impact protection. The suspension system is comfortable, with shoulder straps, a waistbelt and two side handles, and the hinge-style fold makes the Circuit easy to transport. The Circuits square corners make for better coverage when paired with other pads and integrated multi-pad carry system makes it easy to carry multiple pads at once.
