Your postpartum recovery starts here — and FourthWear is built for every part of it. Vaginal delivery or c-section, your body deserves targeted, expert-backed support during postpartum recovery. Nyssa's FourthWear Postpartum Recovery Underwear was developed in collaboration with an Innovation Advisory Board of women's wellbeing professionals — OB-GYNs, Doulas, Midwives, and Pelvic Floor Therapists — to deliver real relief exactly where recovering bodies need it most. At the heart of FourthWear is our patented dual-layer, 360° pocket system, engineered to hold ice or heat therapy securely against the body in three critical zones: Between the legs for perineal pain relief At the c-section incision site for targeted scar healing Across the lower back for postpartum back pain relief The pocket is also designed to hold a pad on the inside of the underwear — so you can manage postpartum bleeding and apply cold or heat therapy at the same time, hands-free. No juggling. No readjusting. Just recovery. Crafted from super-soft, adaptive compression fabric that gently hugs the belly and conforms to your changing postpartum figure, FourthWear stays smooth and seamless under clothing from day one through every stage of healing. ✔ FSA/HSA eligible ✔ Designed with OB-GYNs, Doulas, Midwives & Pelvic Floor Therapists ✔ Perineal recovery · C-section healing · Postpartum back pain · Postpartum bleeding support — all in one
