A snag starts when the outer neoprene or a seam catches a sharp rock, barnacle, or broken shell. Blue70 suits use Yamamoto neoprene in 38, 39, and 40 cell, and the higher cell number improves flexibility rather than resistance to sharp rock, so a flexible suit still requires a little care around barnacles and broken shells. You can't make any swim wetsuit rock-proof, but you can reduce most rock damage before it happens. The knees, shins, seat, and forearms take the most abuse, so your habits around the entry and exit matter more than the suit itself.
Scout first
Walk the shoreline in sandals or booties and find the cleanest line into the water. Barnacles and mussel beds are common culprits, especially on rocks just below the surface. Pick a sandy or gravel path when one is available. If you must cross rock, note the flattest, most stable spots and memorize them for the exit. That minute saves you a torn knee later.
Put the suit on after the rough section
Don't walk barefoot over rocks with the suit half on. Carry or wear it until you're past the sharpest ground, then pull it up. If you need to sit down to pull on the legs, sit on a towel, changing mat, or dry bag. Sitting directly on rock or concrete scrapes the seat panel and can start small holes. This is especially important with the Helix, because its race-focused neoprene is thin and flexible.
Move through rocks with high steps
Most rock snags happen when a swimmer shuffles and drags a shin or knee across a ledge. Lift your feet and set them down deliberately. Use your hands for balance on stable rock so your lower legs don't absorb the contact. If the water is shallow over rock, wade deep enough to swim as soon as you can. Swimming over a rocky bottom beats crawling across it.
Exit with a plan
Decide where you'll leave the water before you get in. Fatigue turns rocky exits into a scramble. When you reach the exit, stand slowly, test the footing with your feet, and use your hands to steady yourself. Don't sit or lean on barnacle-covered rock. Once you're on shore, remove the suit on a towel or grass, not on rough stone.
Rinse, dry, and inspect
Rinse the suit in fresh water after every swim, especially the lower legs, seat, and forearms. Dry it inside out first, then right side out, away from direct heat. While it's dry, check the knees, shins, seat, forearms, and seams. A small nick in the outer face is usually easy to fix. A cut that reaches the neoprene foam or opens a seam needs immediate attention.
Repair small nicks before they tear
Small nicks and shallow cuts can be sealed with Aquaseal neoprene cement. Apply it to a clean, dry area and follow the package directions for cure time. Don't stretch the repair until it has fully cured. For a deep tear or blown seam, contact Blue70 support or a wetsuit repair specialist. Rock damage is wear and tear, not a manufacturing defect, so early repair is the cheapest prevention.
Match the suit to your conditions
If rocky entries and rough shorelines are part of most of your swims, choose a suit that handles repeated use. Blue70's Fusion and Reaction are the more durable choices for frequent swimmers. The Helix is the race-day suit, and its thin, flexible panels need a little more care around sharp rock. For swimrun days with rocky trail sections between swims, the Alliance SwimRun is the Blue70 suit warrantied for swimrun use.
A few small habits protect a good suit. Scout, high-step, sit on a towel, rinse, inspect, and repair. You'll spend less time patching and more time in the water. Happy swimming!
