The Circuit Z is Black Diamond's tri-fold, daily workhorse for the cost-conscious boulderer. It features 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, and a waistbelt. 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.
