Most Roll Gear is made to order, so production and shipping are tracked separately, and timelines vary by style. Rash guards, spats, hoodies, tees, and most other apparel: about 5–14 business days total from order date. Grappling shorts — Embrace the Dark, Neon Lava, and Stars & Scribbles: about 7–14 business days total. All other grappling shorts styles run longer because of the supplier: production typically takes 8–16 business days before the order ships, then carrier transit adds about 7–10 business days, for up to 30 business days total from order date. Shipping is calculated at checkout by destination and weight; standard U.S. retail orders over $75 ship free (applied after discounts, before tax). International orders take longer and are responsible for any customs duties or fees. Custom and team orders are quoted individually at the time of order. Rush and expedited options aren’t available.
Because items are made to order, we offer one size exchange per order, requested within 14 days of delivery. The item must be unused, unwashed, unworn, and in original condition, and return shipping is the customer’s responsibility. Orders can be canceled free within 24 hours; after that a 20% cancellation fee may apply. Damaged, defective, or incorrect items — contact us within 7 days of delivery with photos.
