Microsenders Boulder Baggy Kids' Climbing Shorts
Microsenders’ Boulder Baggy shorts are the heavyweight cotton climbing essential for kids who climb hard, move fast and proudly rep the Problem Child youth community. Built from thick, durable cotton, they’re tough enough for gym circuits, outdoor scrambles and the daily chaos of kid life — all while staying soft, comfy and ready for action.
The funky colour vibe is the star: bold, bright and full of retro‑inspired energy that matches the confidence of young crushers who already know their beta is dialled. These shorts give Microsenders the freedom to high‑step, heel‑hook and run wild between attempts, with a relaxed fit that never restricts movement.
Designed to celebrate the global crew of mini‑senders, Microsenders’ Shorts let kids show off their Problem Child pride with every climb, jump and adventure. Fun, expressive and built to last, they’re the go‑to choice for the next generation of climbers who want their gear to feel as strong as they do.
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.
