A jellyfish sting during an open water swim hurts, and it can turn a good session into a frightening one. The right response matters more than the sting itself: stay calm, protect your face, and get to shore. A full-coverage blueseventy wetsuit covers most of your skin, but it does not make you sting-proof. Tentacles can still reach exposed skin on your face, hands, and feet, and they can cling to the neoprene.
What a wetsuit does and doesn’t do
blueseventy wetsuits are swim-specific, not protective equipment. A full suit like the Helix, Reaction, or Fusion covers your torso, arms, and legs, which reduces the amount of exposed skin a jellyfish can contact. A sleeveless suit like the Reaction Sleeveless leaves your arms bare. A short john like the Glide leaves lower legs and arms exposed. More skin coverage means fewer places a sting can land, but no wetsuit seals out every stinging cell. Tentacles can stick to neoprene and later transfer to your skin when you take the suit off.
First response in the water
When you feel a sting, stop swimming. Look around so you don’t drift into more jellies. If pain or vision changes make you unsure you can swim safely, signal a kayaker, lifeguard, or nearby swimmer and float on your back. Do not rub the area. Rubbing can press more stinging cells into your skin. If you can see tentacles on your suit or arm, leave them alone until you’re out of the water. Swim calmly to the nearest exit point. Thrashing uses energy and can drag tentacles across more skin.
On shore: first aid steps
Before you pull the suit off, rinse the outside of it with seawater. This clears loose tentacles that would otherwise slide across your legs and torso as you strip down. Then remove the suit carefully, rolling it down rather than dragging it against your skin. After that, treat exposed skin.
- Rinse the affected area with seawater or vinegar. Do not use fresh water, alcohol, or urine. Fresh water can trigger unfired stinging cells.
- Remove any visible tentacles with tweezers, a gloved hand, or the edge of a credit card. Do not use bare fingers.
- Soak the area in hot water that is hot but not scalding. Stay in until the pain drops, then reassess. If hot water isn’t available, use a hot pack.
- Watch for worsening pain, hives, swelling, or breathing changes after the soak.
Caring for your blueseventy wetsuit afterward
Once the sting is handled, inspect your suit. Tentacles can hide in the neck, zipper, and cuff folds. Put on gloves and remove any remaining pieces with tweezers. Then rinse the suit thoroughly with fresh water and hang it dry away from direct sun. If the exit or tentacle removal causes a small tear, blueseventy Aquaseal neoprene cement works for small neoprene repairs. Keep a tube in your swim bag if you swim in areas where jellyfish are common.
When to get medical help
Call for emergency help if you have difficulty breathing, chest tightness, swelling of the lips or tongue, dizziness, or a widespread sting. Stings around the eyes or mouth also need medical attention. A lifeguard can often provide first aid and call for help. Do not drive yourself if you feel faint.
Reduce exposure next time
Before your next swim in jellyfish water, check local beach reports and ask lifeguards. A full-coverage blueseventy suit gives you more skin coverage than a sleeveless or short john cut. If you swim where stings are common, consider gloves, booties, and a neoprene hood to cover the remaining exposed areas. Practice sighting so you can look ahead without lifting your head too much and losing body position.
