Product Description
Built for training. Old School on the outside.
Our Performance "1975 Circle" tee puts the 1975 Circle logo in bright white on the left chest of a black tee, finished with Old Glory on the sleeve. This isn't our 60/40 tee. Our Performance tees use a lightweight micro poly fabric, similar to Under Armour or Nike Dri-FIT, that wicks sweat, resists stains and odor, and blocks the sun. Ideal for training indoors or out, all year round.
Features
- 4.0 oz micro poly interlock, 100% recycled polyester
- Superior moisture wicking
- Stain release and odor resistant
- Fade and snag resistant
- UPF 44+ sun protection
- No back logo
- Short sleeve
- White 1975 Circle left chest logo on Black
Fit: Loose fit, true to size. Check the Performance Tee size chart before you order. Wrong-size returns get store credit.
Care: Polyester won't shrink. Wash cold and tumble dry low, and skip fabric softener, which clogs the wicking fabric.
2XL & 3XL: 2XL is $2 more and 3XL is $4 more, to cover the higher cost of larger blanks.
Free shipping to the continental US on orders of $85 or more. All international sales are final.
