baleaf Women's 18" High Waisted Swim Pants Long Swim Capris UPF50+ Swimsuit with Liner and Pockets

I wear capris made of regular swimsuit material and a rash guard, since I burn very easily. Wonder if that would protect against jellyfish? https://www.amazon.com/baleaf-Womens-Waisted-Swimsuit-Pockets/dp/B0FXDY7NJ7/ https://www.amazon.com/Hurley-Womens-Sleeve-Rashguard-Protection/dp/B0CKY65F4T I size down in the rash guard if I'm doing OWS, I feel like they're baggier for wearing while relaxing on the beach and they pick up a lot of drag if they're flapping around in the water.
