Product Description
Built for backstage, the gym and everywhere in between.
Our Open Bottom sweat pants put the Emblem logo in black by the left pocket and OLD SCHOOL in black down the right leg, on Athletic Grey fleece. Deep pockets and open-bottom legs with no cuffs make them the perfect backstage cover-up. They slip on and off easily, even over shoes.
Features
- 8 oz 50/50 cotton/poly NuBlend® pill-resistant fleece
- Unisex fit
- Side-entry jersey-lined pockets
- Covered elastic waistband with inside drawcord
- Open bottom, no cuffs
Fit: These run large. A lot of customers order one size smaller. Check the Sweatpants size chart before you order. Wrong-size returns get store credit.
Care: Wash cold, inside out, and tumble dry low. The 50/50 blend shrinks very little, and low heat keeps the fleece soft and the print sharp.
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.
