SoftCore is our ultra-smooth modal that wears like a second skin—supportive and snug, never suffocating. It’s naturally more delicate, so treat it gently and avoid rough surfaces.

FAQ

Sizes are always weird on me. I need help choosing.
DM @jonnyboy.store on Instagram for sizing help directly from Jonny.
Do jocks, briefs, and thongs all fit the same?
In SoftCore (modal), they’re all designed to be snug—not overly tight. The jockstrap will feel tightest at the back due to the straps by design.
Should I get the same size for Core briefs and Core boxer briefs?
Generally yes—choose your usual size for both in the Core line. If your thighs/glutes are fuller, Core boxer briefs may feel firmer on the leg at first; that’s normal and eases with wear.
I'm in-between sizes, should I size up or down?
The swimwear is designed to be very snug so size up. The SoftCore collection is made of a modal blend and has a less tight fit by nature, size down.
