Future Gym Rat Infant Onesie

Start 'em young. Whether they’re lifting bottles or crushing tummy time, your little swole-mate is already showing serious gains. This ultra-soft onesie is perfect for tiny lifters in training — because it's never too early to build a strong core (of cuteness). Warning: May cause excessive flexing and unsolicited gym selfies from proud parents.

- Envelope neckline for easy changes post-workout (a.k.a. diaper blowouts)
- Guaranteed to outlift the competition in style
- Get ready for drool, dumbbells, and domination. 💪
