The 665 Rally Jockstrap in Blue is a classic men's cotton jockstrap with the 665 logo across the waistband. The maker describes its 95% cotton and 5% spandex fabric as cool, moisture-wicking, and designed to soften with washing. The Stag Standard currently offers two verified sizes: XL and XXL.
Choose your size
| Store option | Maker size | Maker waist range | Store SKU | Maker code | GTIN |
|---|---|---|---|---|---|
| XL | X-Large | 37–39 in. | SF22123 | 22123 | 810001686147 |

Measure around the part of your waist where the waistband will sit, without pulling the tape tight. Compare that body measurement with the maker's range rather than relying only on the size label. These are published maker ranges, not garment measurements or a fit guarantee. If you fall between ranges or prefer less compression, consider how you want the waistband to feel before choosing.

Care
Follow the maker's instructions: wash cold, dry with a low heat setting, and do not iron or use bleach. Wash before first wear and after use, allow the garment to dry completely, and store it clean and dry. Check the waistband, stitching, pouch, and straps for stretching, tears, rough edges, or other damage before wearing again.
