Stretch Flex Trainers are built to stretch your sack low, proud, and tight. This 2-pack gives you both a short stack and a long tugger—so you can mix it up, stack ’em deep, or keep it minimal depending on how heavy you’re feeling.

Crafted from Fort Troff’s signature premium silicone, both rings have serious flex but keep a strong grip. The added bumpers prevent rolling and keep each trainer locked in right at the base of your balls. That means longer wear, better stretch, and no annoying slippage mid-session. Whether you’re sporting these under your gear, at a party, or just at home for the pull, these trainers give your balls the bold hang they deserve.

• 2-pack set – includes short stack and long tugger for different stretch levels
• Premium silicone – soft, stretchy, and tough enough for serious grip
• Anti-roll bumper design – keeps the stretcher locked in place on your nuts
• Stackable style – double them up for deeper pull and heavier hang
• Show-off FT logo – branded front lets you rep your kink loud and proud
• Comfort-fit engineering – tight where it counts, forgiving where it needs to be

If you’re into CBT, low-hangers, or just love the feeling of stretch, Stretch Flex Trainers give you options. Rock ’em all day or wear them in the heat of play—these rings were made for guys who take their sack work seriously.

Only Naughty Boy stocks Fort Troff gear this filthy and functional. We don’t do half-measures—we do gear that performs and gets noticed.
