The hy. Test Edition ♡
You're looking at one of the first 100 hy. Performance Sports Bras ever made.
We're releasing our first production run as a special Test Edition and inviting parents and girls to help us perfect the final product.
The fabric, fit and support are ready to be put through their paces. However, our manufacturer didn't apply the premium silicone logo finish we specified for the final design.
Rather than allow perfectly wearable activewear to go to waste, we're offering this first batch at a special £14 Test Edition price.
Wear it. Wash it. Move in it. Then tell us what you think.
Complete our short feedback survey afterwards and we'll also give you 15% off your next hy. order.
Your feedback will help shape the final version. ♡

The hy. Girls Performance Sports Bra has been designed for that in-between stage when girls' bodies are beginning to change, but they still want to run, jump, train and play without feeling self-conscious.
Created specifically for growing girls, this is a comfortable, supportive girls puberty bra that can be worn discreetly underneath a school PE top or everyday clothing, or worn on its own with our matching hy. leggings or shorts.
The soft, stretchy performance fabric gently holds and supports the body, helping to reduce uncomfortable movement during exercise without feeling heavy, restrictive or overly structured.
With a scoop neckline, racerback design and supportive underband, it provides mid-level support while still feeling lightweight enough for everyday wear.
It's the kind of piece we believe should become a staple in every growing girl's wardrobe.
Why she'll LOVE it ♡
Medium support for running, PE, gymnastics, training and everyday activity
Helps reduce uncomfortable movement and bouncing during sport
Soft, stretchy fabric that moves with her body
Supportive fit designed to gently hold and shape

Puberty shouldn't mean girls suddenly feel uncomfortable doing the activities they love.
A well-fitting girls sports bra can give a growing body the extra support it needs while helping girls feel secure and comfortable when they're moving.
Wear it under a T-shirt for school PE and sports days, layer it underneath everyday clothes, or make it part of a full hy. activewear set.
One simple layer. A lot more confidence.
