Stock up and save — 3 pairs of OB-GYN recommended FourthWear Postpartum Recovery Underwear plus a Between Legs Perineal Ice/Heat Pack at our special "Buy 3 & Save" price.
FourthWear is the first postpartum underwear built with a dual-layer, 360° pocket system that holds ice or heat therapy securely in place — between the legs for perineal recovery, over the c-section incision site, and across the lower back where postpartum bodies need relief most. 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 simultaneously — completely hands-free.
Crafted from ultra-soft, adaptive-stretch compression fabric, FourthWear moves with your body and gently conforms to your changing postpartum figure without digging, shifting, or bunching.
Nyssa's Between Legs Perineal Ice/Heat Pack is lightweight and uniquely contoured to deliver targeted perineal pain relief — but it's equally effective over a c-section scar or across the lower back for postpartum back pain and period cramps. Pair it with a pad inside the FourthWear pocket for added postpartum protection, all in one hands-free setup.

Stock up so you always have a clean pair on hand during the early weeks. The set includes three pairs designed for daily wear and postpartum needs.
Dual-layer pockets hold ice or heat packs securely, keeping therapy exactly where you need it. The pocket also accepts a pad so you can manage bleeding and relief at once, hands-free.
The contoured between-legs pack soothes perineal pain and can be placed over a c-section incision or across the lower back. Use cold for swelling and heat for relaxing tight muscles, per your provider's advice.
Focus on fit, pocket placement, and how you plan to use heat or cold therapy.
- Choose the right fit: Look for underwear that sits comfortably at your natural waist and offers gentle compression without digging in; consult the brand size chart when possible.
- Think about recovery type: If you had a c-section, confirm the pocket sits over the incision area; for vaginal births choose a style that supports perineal placement.
- Plan for pads and therapy: Pick underwear with a pocket large enough for both a pad and a cold or heat pack so you can manage bleeding and relief together.
- Decide how many pairs: Stock at least two to three pairs so you have spares while others are being washed during the heavy bleeding stage.
- Ask about care: Check the included care instructions for washing and pack cleaning to keep both underwear and therapy packs in good condition.
Are these eligible for FSA or HSA reimbursement?
Yes, these FourthWear postpartum underwear and therapy pack are listed as FSA and HSA eligible.
Can I use the pack after a c-section?
Yes, the contoured pack can be placed over a c-section incision for comfort and lower back relief, but check with your care provider first.
How should I clean the underwear and the pack?
Follow the product care instructions included with your order; in general, remove therapy packs before washing underwear and clean packs per manufacturer guidance.
How do I pick the right size?
Use your current measurements and the brand size chart when available, and choose a fit that feels supportive without being restrictive.
What is the returns and shipping policy?
We ship from a US warehouse, offer free US shipping on orders over $100, and accept returns within 30 days with human customer support to help.
How long should I use cold or heat therapy?
Use short sessions of cold or heat as recommended by your provider; if you have concerns about timing or symptoms, contact your healthcare professional.
