The Glottis Monster Unisex Organic Cotton T-Shirt — Tan

This one’s for freedivers.

An inside joke, really — but if you know, you know.

“I got 1000 problems and my glottis ain’t one.”
Freedivers love to blame everything on their glottis opening. This T-shirt is a gentle reminder to smile, relax, and keep training instead.

Designed for people who spend their time thinking about breath, pressure, and technique, the Glottis Monster Tee is made from premium organic cotton and built to be worn on rest days, training days, and everywhere in between.

Playful, niche, and unapologetically specific — just like freediving itself.

Made on demand

This T-shirt is made especially for you once you place an order.
Producing on demand instead of in bulk helps reduce overproduction and unnecessary waste — while keeping quality high and intentional.
