Microsenders’ Apparel is the heavyweight kids’ climbing tee built for the next generation of crushers who climb hard, dream big and proudly rep the global Problem Child youth community. Made from ultra-heavyweight, stonewashed natural cotton, it delivers that premium, structured feel that stands up to playground chaos, gym sessions, outdoor scrambles and the endless wash cycles that come with kid life. Tough, comfy and built to last — exactly what young climbers need.
The design is bold, bright and full of personality, celebrating the worldwide crew of mini‑senders who love movement, adventure and figuring out problems their own way. It’s a tee that says they belong to something bigger: a community of young climbers pushing limits and having fun doing it.
Strong, expressive and unmistakably climber‑coded, Microsenders’ Apparel is the go‑to shirt for kids who are already hooked on the sport and proud to show it.
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.
