CELLBLOCK 13 underwear and clubwear with a raw edge
CELLBLOCK 13 is made for men who see underwear as more than a base layer. The collection combines jockstraps, singlets and clubwear with bold straps, snaps, mesh and functional details. At GUNDERWEAR you'll find ranges including Tight End, Anti-Chrome, Iron Grip and Chain Reaction.
Snap-off and snap-up jockstraps
Many CELLBLOCK 13 jockstraps use snaps in the pouch or straps, giving styles such as Tight End, Kennel Club and Iron Grip their recognizable technical look. Some versions can be partially opened; check the product description to see exactly how each style is constructed.
Singlets, jock briefs and removable details
Alongside jockstraps, the collection includes singlets, jock shorts, socks and jock briefs. Some styles have a C-ring, a removable pouch or a combination of open sections and mesh. This makes them especially suitable for club, party and fetish looks.
Choose by style and function
The collection names do not always make it clear which parts can be removed or opened. Read the product text and view all images before choosing. Also use the size chart, as sturdy straps and singlets can fit differently from regular underwear.
Frequently asked questions about CELLBLOCK 13
What does snap-off or snap-up mean?
It refers to snaps that allow part of the garment to be opened or removed. The exact position and function vary by item.
Does every CELLBLOCK 13 style have a C-ring?
No. Only products that explicitly mention it in the title or description include a built-in or supplied C-ring.
Are the singlets designed as sportswear?
The singlets in this collection are mainly designed as fashion and clubwear. Check the product information if you want to use one for a specific activity.
How does CELLBLOCK 13 fit?
Use the size chart for each product. With sturdy waistbands and close-fitting singlets in particular, your measured waist or body circumference is more important than your usual clothing size.
