    Men's Trunk Underwear

    CockSox trunks give you that square-cut look with real pouch support, not a flat front. Every trunk here uses our Contour pouch, shaped for the male anatomy to keep you steady through the day. You’ll find solid trunks, mesh and semi-sheer styles, plus bold prints across SUPPLEX®, Modal, Mesh, Sheer, Bamboo and elastane blends. Sizes S to XL cover everyday neutrals through to bright colours and statement patterns, all cut to hug your glutes and sit clean under pants or shorts.

    What makes CockSox trunks different from regular boxer briefs?
    CockSox trunks build around the Contour pouch, which follows your natural shape instead of just squashing it. You get a body-hugging back, high-cut sides and a sharper outline that still feels secure for daily wear.

    How does the Contour pouch feel in trunks?
    The Contour pouch gives a close, supportive hold, reducing shifting and helping to cut down on chafe. Many guys say it feels more natural than flat-front trunks, especially on active days or long hours on your feet.

    What fabrics do CockSox trunks use?
    Foe active pursuits and everyday comfort, our SUPPLEX and FlexMode collections move with you through every step in your day. Modal and Bamboo are eco-friendly and sustainable fabrics that offer a lighter fit and feel, while still retainiing our signature support. And for your sexy side, our Mesh and semi-sheer fabrics bring the tease, while also deliveing a cooling freshness that lifts your day ahead of date night.

    How do I choose size and look after my trunks?
    Pick your usual CockSox or waist size from S to XL for a snug, supportive fit. If you sit between sizes you can go either way in most of our fabrics. But we do suggest going up to the next size in mesh and semi-sheer fabrics as there is less stretch in these materials. Wash your CockSox trunks in cold or cool water with mild detergent, skip bleach, and line dry so the pouch shape, colour and waistband stay in good condition.
