Cold water is a lot friendlier when you can bring power inside your drysuit. The DrySuit Connector I routes juice from your Bigblue canister through an Apeks-style female port to run heated vests and undergarments, so long deco stops stop feeling like endurance events. The pass-through is built to stay dry where dry matters most. Pair it with your canister and heated layers, and stretch your cold-water season.
