Ascensionist is the heavyweight kids’ climbing tee built for young dreamers who look at big walls and think, yeah, I’m going up there one day. Made from thick, durable cotton, it’s tough enough for gym circuits, outdoor scrambles, school‑yard chaos and the endless wash cycles that come with kid life. Soft, structured and ready for adventure.
The design channels pure inspiration — bold, uplifting graphics that celebrate big walls, big goals and the fearless spirit of the next generation of climbers. It’s a tee that tells kids they belong on the rock, that every move counts, and that the summit is always worth chasing.
With a comfy, movement‑ready fit, Ascensionist keeps Microsenders feeling strong and looking sharp as they build the skills and confidence to take on bigger and bigger challenges. Fun, empowering and proudly climber‑coded, it’s the perfect shirt for kids who are already dreaming higher.
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
Model is 5'11" and 74kg and wears a large size. This product is a Regular Fit styling and cut. We sell both "Regular Fit" and "Big Fit" T-Shirts, with the latter having a wide and more baggy silhouette.


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.
