Educational resources & donation included with every purchase. Learn more.

Our leggings are designed to keep up with all your adventures in and out of the water! Durable enough for the dive boat, soft and supple enough for the hammock. Stylish sun protection for the win!

Kelps represent the largest species of algae in the world, with some, like the giant kelp, exceeding 100 feet (30 meters) in length. Giant kelp is also one of the fastest-growing organisms in the ocean, growing up to 2 ft per day! Gas-filled bladders beneath the kelp’s blades, called pneumatocysts, float the kelp towards the water’s surface, while the holdfasts keep them anchored in place, creating the iconic forest-like appearance.

Advocate Apparel Inspired by Kelp Forests

Kelp forests can be found on over 1/3 of our planet’s coastlines and are home to thousands of marine species, including abalone, crabs, lobsters, fish, sharks, marine mammals, and sea birds. They support commercially and culturally important fisheries, protect coastlines from erosion, and support a large ecotourism industry.

Unfortunately, warming seas, loss of keystone species that keep kelp grazers in check, unsustainable fishing practices, and pollution are causing kelp forests to decline globally.

These are rad

I LOVE these leggings. They make me want a kelp leg sleeve tattoo! I ordered a size Small. I'm 5'4 athletic petite build and ~112 pounds. The Small fits great, although the waist is a little big. I know the XS would be too small for my hips and legs. If these had a drawstring, they would be perfect. Please start adding a drawstring to the women's sizes!

So many compliments!

These leggings might just be my favorite design! The pattern is very classy and I can wear them equally well for work at the office, yoga at the gym, or paddle boarding at the lake with different tops. As with all Waterlust leggings, the pockets are AMAZING and the fabric is smooth and comfortable. Great quality and durability.

So Beautiful!

Love these swim leggings! These are my second pair is swim legging I have purchased from Waterlust. I am so impressed by the whole experience of making a purchase with you all and the quality if the products. The shipping materials are as earth friendly as possible, you get fun emails learning about kelp, some of the profits from your purchase goes toward research for kelp, and they are high quality and beautiful legging.

Fun bonus, there is a great little saying written in the hemline. Love it!

Waterlust: My Dive-Ready, Eco-Friendly Obsession!

I can’t rave enough about Waterlust tights! As a dedicated diver, my eight pairs, worn over the past four years, are my ultimate go-to for every dive—rotating through them weekly for at least one dive, and they still look and feel as good as new. These tights are incredibly durable, with no fading or stretching, making them my top choice for protection against jellyfish stings and sun exposure while diving.
At 5’4” and 185 lbs, the large tights fit me perfectly, offering a comfortable, curve-hugging fit that never feels restrictive. The medium tops are just as spot-on, keeping me comfy and confident in and out of the water. What makes Waterlust even more special is their use of recycled materials—such a fantastic way to support sustainability! Plus, their donations to marine conservation programs align perfectly with my passion for protecting our oceans, making every purchase feel like a win-win-win for me, the environment, and fellow ocean lovers.
I’m on a mission to own every design they offer, and whenever a new one drops, it’s straight to my cart without hesitation. The vibrant patterns, unbeatable quality, and eco-conscious mission make Waterlust tights a no-brainer. I’m a lifelong supporter and can’t recommend them enough to anyone who loves diving or wants stylish, sustainable activewear! #narcedmermaid #SlayEatRepeat
