Midweight Fleece Crewneck Sweatshirt Care Instructions
Please refer to the care instructions above to keep your gear race-ready.
- 8.4 oz midweight fleece — warm enough for a wet qualifying session, soft enough for a post-race wind-down.
- 80% ringspun US cotton, 20% polyester — premium feel with a durable construction built for the long haul.
- 2-end fleece face perfect for bold DTG printing — give #81 the vivid tribute he deserves.
- 1x1 rib with spandex cuffs and bottom band — like traction control for your sleeves.
- Dropped shoulder and classic fit — relaxed like Piastri’s driving style, but never off pace.
- Double-needle topstitching throughout for race-spec reinforcement.
- Sustainably made from USA-grown cotton — engineered with care, just like Oscar’s racecraft.
