What our customers are saying
Customers say these shorts are exceptionally comfortable and feel like regular underwear, with many praising their soft texture and perfect compression. Users appreciate the worry-free sleep and confidence they provide during periods. Many reviews mention the shorts work well for gym workouts and daily wear. However, some customers experience leakage issues, particularly side leakage and concerns about gusset width and positioning. Common feedback includes requests for lighter absorbency options and more color choices. While most find them true to size, some recommend sizing up for thicker thighs. Several users note durability concerns with seams separating after extended wear.

    Absolutely a Dream

    The dream shorts are probably my most favorite undies of all time! Not only are they comfortable, but help to keep bladder leaks contained. I have a health condition that causes extreme bladder leaks but while out and about I can feel more confident wearing these knowing I’m better protected. I understand why prices have risen unfortunately, so looking for sales on these constantly as I can’t leave home not wearing these undies!

    Super comfy but not enough coverage in the front

    Just got mine and they fit great and feel great. The only problem is the built in pad doesn’t go far enough forward. I had to put a small pad at the front to stop it from spilling out the top

    Sleep without the worry

    Since having my third baby my period is a little insane. I wear these to bed and on heavy days under clothes! They’re so comfy and help me feel more confident on days where I’m less comfortable!
