It uses a lightweight polyester-rayon blend, a cotton-lined ultra-long gusset with Fresh Fix Technology, and a patented 360 LeakSeal trim; the brand rates it as equivalent to 7-9 regular tampons. User reviews note that while it is thin and comfortable for light flow or backup use, the gusset coverage may be insufficient for heavy flow and can leak on heavier days.","url":"https://www.simons.ca/en/women-underwear/sleepwear-loungewear/sleepwear-loungewear-bottoms/super-leakproof-dream-boxer-absorption-high--22786-26137?colourId=0","brand":"Knix","condition":"new","product_category":"women

compressive seal that a relaxed fit relies on for leak protection.","leakseal_activation_flatten_the_gusset":"The patented 360 LeakSeal trim creates a barrier only when the ultra-long gusset lies completely flat against the skin from front to back; after pulling on the boxer, running a finger along the gusset edge to unbunch any folds and ensuring the trim sits outside the labia — not tucked in — triggers the full seal and dramatically reduces side and rear leakage during sleep.","laundry_routine_no_bleach_no_fabric_softener":"Knix explicitly warns that bleach and fabric softener degrade
