About Key-shirt

Thoughtful ideas. Practical solutions. Stronger connections.

At Key-shirt, we believe small ideas can make a meaningful difference.

We create practical, creative products inspired by everyday challenges and the opportunity to make life a little easier, more connected, and more meaningful.

Our two brands, SmileGuard Sportswear and We-Shirt, serve different needs but share a common philosophy: simple tools can make everyday experiences better.


Smile Guard Sportswear

Practical solutions for student athletes.

Keeping track of a mouthguard shouldn't be another challenge on game day.

SmileGuard Sportswear creates convenient mouthguard holders that attach to sports bags, helping young athletes keep their mouthguards easy to find and a visual reminder to clean between practices. Custom team options let teams incorporate their names, colors, and identity into their gear.

Our goal: Make everyday sports routines easier with practical products designed for athletes and teams.

We-Shirt

Small shirts. Big conversations.

Children are naturally curious about one another, but starting a conversation or making a new friend isn't always easy.

We-Shirt was created to make those first connections a little easier.

Our mini T-shirt conversation tools attach to backpacks and feature prompts that invite children to share their interests, favorites, and something about themselves. They provide a natural starting point for conversation, helping children discover common interests and practice connecting face-to-face.

Designed for schools, camps, and youth communities, We-Shirt encourages the everyday conversations that help children build relationships and a sense of belonging.

Our goal: Help children move beyond simply being together to talking, connecting, and getting to know one another.

Our Why: Making Room for Connection

Through more than 20 years of experience working in schools, we observed how children's social experiences were changing. As schedules became more structured and activities increasingly organized around adult direction, opportunities for spontaneous conversation and unstructured peer interaction could become harder to find.

Yet children remain naturally curious, and human beings are social by nature.

We believed there had to be simple ways to encourage children to put down their phones, engage with one another, and rediscover the value of real-life conversation.

That belief inspired We-Shirt.

Our work in pediatric nursing and education also reinforced another lesson: everyday challenges often have practical solutions. Sometimes, a small change in a routine or a thoughtfully designed tool can make a difference.

That philosophy inspires both of our brands.

Whether we're helping a child find the courage to start a conversation or helping an athlete keep track of a mouthguard, we look for opportunities to make everyday experiences better.


 

Meet the Founder

Key-shirt was founded by Karen Kearsley, a registered nurse and educator with more than three decades of experience working with children and families.

Her work in school nursing and pediatric neurology inspired her to look for practical ways to address real-life needs, from helping children build connections with their peers to creating products that make everyday routines easier.

Key-shirt brings that perspective into product innovation: observe a challenge, imagine a simple solution, and create something useful.


Different Products. Shared Purpose.

SmileGuard Sportswear helps young athletes keep an important piece of equipment close at hand.

We-Shirt gives children an easy way to start conversations, discover common interests, and build connections.

Both reflect our belief that thoughtful ideas can improve everyday experiences.
