Need Help Choosing a Size?
Between sizes?
We recommend sizing up for a more relaxed fit, or down for a more snug, supportive feel, depending on your personal style.
Prefer oversized or fitted?
Many of our products are designed with either a relaxed or athletic cut. Check the product description for specific fit notes.

Washing and Care
Please note that all garments are made with high-quality materials. Follow the care instructions on the label to avoid shrinkage or fabric warping.
Reminder
THIRTY3 hoodies are made to order, so we recommend checking your size carefully before purchasing. This helps reduce waste, returns, and ensures a better fit from day one.
