Swim. Bike. Run. Poop. Merry Christmas.
Forget dashing through the snow. Santa's got an Olympic-distance triathlon to finish, and he's making one very important stop before the starting line.
This festive, ugly Christmas sweater-inspired sweatshirt features the full triathlon experience: a mandatory pre-race porta-potty visit, 1.5K swim, 40K bike, and 10K run. All wrapped up in Christmas colors, reindeer, snowflakes, and questionable race-day decisions.
Perfect for holiday parties, triathlon club gatherings, Christmas morning, or reminding your family that even Santa has a training plan.
Take your sport seriously. Yourself, not so much.

How to Measure
Body Length: Measure from the highest point of the shoulder to the bottom hem.
Body Width: Measure straight across the chest, approximately 1" below the armholes, with the shirt laid flat.
Sleeve Length: Measure along the sleeve from the shoulder seam to the sleeve opening.
Measurements refer to the garment itself, not your body measurements. For the best fit, compare these measurements with a T-shirt you already own.
