Frequently Asked Questions (FAQ)

What is Airlume combed and ring-spun cotton fleece?
Airlume cotton undergoes an intensive combing process to remove 2.5x more impurities than standard ring-spun cotton. Blended with poly-fleece, it creates an exceptionally smooth surface, extreme interior softness, and minimal pilling.

Is this sweatshirt thick enough for late-night or early-morning outdoor training?
Yes. The 10 oz. (339 g/m²) heavyweight construction acts as a dense thermal barrier, making it ideal for brisk 5:00 AM warm-ups and cold-weather recovery layering.

How oversized is the fit? Should I size down?
The sweatshirt is intentionally crafted with a relaxed streetwear cut and slightly dropped shoulders. If you prefer a loose, modern drape, stick to your standard size. For a traditional tailored fit, order one size down.

How do I wash this sweatshirt to preserve the back frame graphic?
Turn the garment inside out before washing on a cold cycle. Avoid direct ironing over the graphic print and use low heat or hang dry to maintain both the crisp frame print and fleece loft.
