Seaweed Boxer Briefs

Gentle Black


Every journey starts with a solid foundation, and so does your outfit. Whether you’re in Berlin, Bogota or Bali, the ultra-comfy and durable seaweed fabric used in the Karma Boxer Briefs helps comfort your skin, kills bacteria, manages sweat, and resists odors.

The tailored design fits perfectly and looks classy. The leg length is just right. The ball pouch gives support and comfort. And the comfortable waistband elevates your style and calms your mind since it is entirely made from natural rubber. No plastics on your skin, or in the ocean.

The fabric is a blend of Asian seaweed and premium Indian organic cotton. The seaweed protects from bacteria and soothes the skin. It has a silky-soft cashmere feel and regulates your body temperature.

Karma Boxers look great, feel great and do great. They will be your go-to pair in the underwear drawer.

The incredible benefits
of seaweed fiber

"I tested the seaweed T-shirt and it really feels different, more solid, smoother and silky than pure cotton shirts. I think it is a better, more luxurious alternative to other organic materials. And I am blown away by its carbon credentials."

Jonah G.
Los Angeles

"What's not to love about these T-shirts? They feel nice and soft, and the fit is just right: not baggy at all but not too tight either. And it's true they don't start to smell funny even after wearing them for several days :)"

Bali Ubud

"Seaweed is not an alternative but a real game changer! Yes and it feels good on the skin and is good for the soul!"

Darius Gondor
Cairo & Shanghai

"The Karma Seaweed Tee feels great, quite special compared to my other T-shirts. The seaweed adds a subtle shine. I love the ocean and I love the fact that the material actually comes from the ocean. Its quite the innovation."

Philipp G.

"Seaweed feels really soft on the skin. And it makes me feel safe knowing that it is part of the solution, not adding to the problem of climate change."
