Patented dual-layer, 360 degree pocket system holds therapy packs across three critical zones for perineal, c-section, and lower back relief. Use ice or heat therapy exactly where it helps, hands-free.
Insert a pad inside the inner pocket and a therapy pack outside, so you can manage postpartum bleeding while receiving cold or heat therapy. No juggling pads, packs, or readjusting.
Crafted from super-soft, adaptive compression fabric, FourthWear stays smooth under clothing and gently hugs your changing postpartum figure. Wear it day or night as your body heals.
Look for features that match your delivery, pain points, and daily routine to find the most useful option.
- Delivery type: If you had a c-section check that the front pocket can sit over the incision, for targeted therapy and scar support.
- Pain relief needs: Choose a design with pockets placed for perineal, lower back, and uterine pain if you want multi zone therapy options.
- Size and fit: Support should feel snug but not restrictive. Look for adaptive compression that accommodates changes in the early weeks.
- Pad compatibility: If you want hands-free bleeding management, confirm the underwear accepts an interior pad alongside a therapy pack.
- Care and returns: Check care instructions before purchase and confirm return windows in case you need a different size or fit.
How do the therapy pockets work?
The dual-layer pockets are shaped to hold ice or heat packs in three zones, between the legs, over a c-section incision, or across the lower back. They also accept an interior pad so you can combine bleeding management with cold or heat therapy.
Can I use these after a c-section?
Yes. The front pocket is designed to sit over a cesarean incision for targeted cold or heat therapy and supportive scar care.
Will these fit my changing postpartum body?
The product uses super-soft, adaptive compression fabric that conforms as your body heals, offering gentle support from day one through recovery.
How should I care for the underwear and packs?
Remove therapy packs before washing and follow the garment care label. Gentle washing and air drying helps preserve compression and pocket function.
Can I wear a pad and a therapy pack at the same time?
Yes, the pocket system is designed so a pad can sit inside while a therapy pack sits against the body, enabling hands-free bleeding management and therapy.

We ship from a US warehouse, and orders over $100 ship free within the US. We offer 30-day returns and human customer support if you need help with sizing or returns.
