Postpartum recovery gets easier when your underwear can do two jobs at once, holding an oversized pad in place and holding a cold or warm pack right where you're sore.

The base option on this page is one pair by itself, with no pack included. If you want the contoured Between Legs pack, or two or three pairs, those options are in the selector below. Choose your size and set count there, since current price and availability show up live.

Why I picked it: I kept coming back to this pair because it solves something nobody warns you about, which is that you'll be managing a giant pad and an ice pack while also trying to walk to the bathroom and back. The interior pocket means you're not holding anything in place with one hand. I like that the waistband comes up high enough to stay off a C-section incision, and that you can fold it under your belly instead if that feels better. It's expensive for underwear, so here's my honest take: start with one pair, see how the fit and the pocket work for your body, and add pairs if you love them.

Best for

  • Vaginal or C-section recovery, from hospital days through the weeks after
  • Keeping oversized postpartum pads from shifting or riding up
  • Wanting a cold or warm pack held in place without holding it yourself
  • Late pregnancy too, worn over the belly or folded under it

How the pocket works

  • A 360-degree interior pocket lets a pack sit in front, in back, at the sides, or in the gusset
  • The dual-layer construction keeps a fabric layer between the pack and your skin
  • Sized for Nyssa's contoured Between Legs pack; the base option doesn't include a pack
  • The widened gusset and full-coverage seat hold a pad in place, and the underwear itself isn't absorbent

Fit, fabric, and sizing

  • 85% recycled polyester and 15% spandex, with stretch in every direction
  • High waist that can sit above a C-section incision or fold under the belly
  • Full-coverage seat, smooth waistband, no clasps or hardware
  • Gentle, light compression only, closer to a soft hug than shapewear
  • Sizes XXS/XS through 3X/4X; size down if you're between sizes, since the fabric is very stretchy

Choosing your set count

  • One pair on its own, no pack
  • One pair plus one Between Legs pack
  • Two pairs plus one Between Legs pack
  • Three pairs plus one Between Legs pack

Worth knowing before you pick: each bundle includes one pack; higher set counts add pairs of underwear. Even the three-pair option includes one Between Legs pack, so if you want a frozen one and a warm one ready at the same time, you'd need a second pack.

Using ice or heat comfortably

  • These options provide comfort support and don't replace medical care
  • Packs never touch bare skin; the garment layer is the barrier
  • Keep cold sessions to about 20 minutes, then give your skin a break
  • Don't sleep with a pack in
  • Cold can feel good for perineal soreness; warmth may comfort your abdomen or lower back, and never goes on an open wound or incision
  • Follow Nyssa's microwave and freezer directions for the pack itself

Care

  • Machine wash cold and tumble dry low
  • Rinse and fully dry the pack by hand; it doesn't go in the washing machine

If you're stocking the rest of the recovery drawer, my postpartum essentials picks gather the things moms actually reach for in those first weeks, and new mom essentials covers the wider list. The matching FourthWear Postpartum Bralette uses the same pocket idea up top, with breast and chest packs instead.
