Boulderer is the heavyweight cotton climbing tee for the purists — the climbers who don’t want ropes, don’t want harnesses, don’t want excuses… just pads, power and problems. Made from thick, durable 330gsm cotton, it delivers that premium, structured feel built to handle gym abuse, sandstone slaps, granite thrutching and the endless wash‑and‑repeat cycle of real bouldering life. Tough, comfy and ready for the next session.
The design celebrates the climbers who live low to the ground but dream sky‑high — bold, clean and proudly boulder‑coded. It’s a tribute to the senders who chase perfect sequences, love the fight, and know that nothing beats sticking the crux move after ten tries and a little screaming.
With a movement‑ready fit and confident aesthetic, Boulderer keeps you looking sharp from warm‑ups to top‑outs. Strong, expressive and built for the climbers who will always choose pads over ropes.
NOTE: some sizing is done via a "flat lay measurement" (i.e. measuring from one side of the body to the other, rather than circumference). If you prefer a circumference, you can generally just double the number.

THE FITMENT
*BIG FIT STYLING* MODEL WEARS A SMALL. These tees are designed with large, "BIG fit" in mind. The model is exactly 6ft (182cm) & 81kg, and wears a SMALL (S) size. We recommend only choosing M and bigger if you're a heavy build and/or substantially taller than 6ft.
ULTRA-THICK ORGANIC COTTON ... Not Overpriced Cloth with a fancy logo
Eco-friendly, high-durability styles, made from predominantly natural materials, with most t-shirts crafted using 300gsm+ cotton. Even our printing ink is vegan and water-based.
VIBRANT & DURABLE PRINTS
We use a mix of DTF (direct to film) and DTG (direct to garment) printing techniques to maximise the vibrancy of our designs, as well as protect them from multiple washes and thrashing at the crag.
DOUBLE STITCHING
Locked in seams for durability over repeated washes and outdoor use.
INSANELY THICK COTTON
The minute you unwrap your t-shirt, you will honestly feel the difference. Most of our products are over 50% thicker than every other t-shirt you own. You can hold us to that.
