Protective Briefs are -Waterproof -Washable -Leakproof Protective Briefs work with our Flexible Absorbency System, giving you complete protection for minor to major incontinence, daytime or nighttime. Whether you are seeking a cloth solution for the financial freedom of disposables, or pure comfort to truly relax, Threaded Armor Protective Briefs give you confidence in your active lifestyle. This innovative Flexible Absorbency Insert System is like none other in the cloth diapering community. This two-piece solution takes the absorbency you need and wraps it into a perfectly trim insert. Contoured edges increase performance and absorption over other commercially available flat folded rectangles. Two components make up the Flexible Absorbency System. The Contoured Insert: Crafted from three layers of thirsty microfiber, this insert possesses a pocket to secure a second absorbent pad. By stacking inserts, you mitigate the bulk of a folded insert. The Contoured Insert flares out in front and back while giving you a custom-fitted trimness in between. The Step-up Insert: This two-layered microfiber pad is sewn in a perfectly contoured shape to slip inside the Contoured Insert. Stack multiples inside or behind the Contoured Insert to customize your needs, and "step up" your absorbency.
