Triathlon Checklist Tee - Youth
Couldn't load pickup availability
The Triathlon Checklist Tee is for the kid who already knows race morning means way more than just showing up and cheering.
The small On A Box™ logo keeps the front clean, while the back turns the classic triathlon packing list into something a little more fun. Goggles. Bike. Helmet. Shoes. Snacks. Sour gummies. Positive thoughts—briefly. It’s everything that somehow ends up spread across the hotel room, transition area, and back seat before the race even starts.
Perfect for packet pickup, race weekend, cheering from the sidelines, travel days, or matching the triathlete in the family.
This youth tee is made with a soft, lightweight tri-blend designed for all-day comfort—from early alarms and cowbells to post-race pancakes.
Soft enough to live in. Dumb enough to be On A Box.
Make it a family thing: Also available in Men’s / Unisex and Women’s fits.
Take your sport seriously. Not yourself.
