YOJOY Sanitary Shorts
[For regular to heavy flow, with wings] Comfortable yet stays in place & leak-proof! Feel secure
Secure and leak-resistant without being too tight.
These sanitary shorts are compatible with winged pads, making them easy to use on normal to heavy flow days.
YOJOY sanitary shorts are designed to address the concern during menstruation of wanting comfort without tightness, yet also fearing pad slippage and leaks.
A survey showed that about 40% (*) of women who wear sanitary shorts actually don't want tightness, but feel forced to wear constricting sanitary shorts during their period.
For these women, we pursued a comfortable fit that is easy to wear, yet prevents pad slippage and leaks. They are compatible with winged pads and suitable for normal to heavy flow days, making them ideal for anyone who wants to spend their period even a little more comfortably.

Gathered tape in the crotch area enhances pad fit, helping to prevent slippage.
The waterproof fabric is attached to the main fabric side, not as a floating gusset, for a design that considers menstrual fluid leaks. The larger area at the rear also provides peace of mind on days when back leaks are a concern.

■ How to choose your size
Sizes available are S, M, L, and LL.
・Choose a size that gently conforms to your body, using your usual brief size as a guide.
・If you dislike a constricting feeling during menstruation, an extra-relaxed size is also recommended if you are unsure.
・If you prioritize pad slip resistance, choose a size that fits snugly without being too loose.
・Aim for a size where the waist and leg openings don't dig in, and that securely covers your abdomen to your lower back.
■ About the fabric feel
The main body uses a soft, stretchy rayon-blend fabric.
It has a smooth feel, is less prone to stuffiness, and is a comfortable material to wear during menstruation. The front waist has a folded finish, and the back waist and hems are free-cut, using no elastic to reduce tightness.
Seams at the sides and waistline are flat-finished for a gentle feel against the skin. Brand and care labels are placed on the outside of the product to minimize any itchy feeling.
■ How to choose a color
YOJOY offers a range of colors that can be chosen to suit your mood or outfit.
・Mustard (KA): Gives a warm impression. Also recommended as a color that is less likely to show through outer clothing.
・Coral (RP): For days when you want to feel bright and soft, boosting your mood.
・Sora (BU): A light and clean color.
・Sumi (BL): A calm impression, easy to wear daily.
・Apricot (BR): Blends well with skin, recommended as a color that is less likely to show through outer clothing.
■ How to use
・Wear directly against the skin.
・If using winged pads, tuck the wings into the mesh floating gusset.
・Ensure the pad is securely aligned with the crotch area.
・Wear the shorts so that the waistband reaches around your navel, gently conforming to your body.
