How to Pick the Best Period Underwear
-
Layers for your flow
Heavy days need more protection than light days. Pick a pair made for your flow. Kischt has three absorbent layers, made for heavier flow days.
-
Coverage where you need it
See how far the protective part goes. In Kischt, it runs up toward the back. That gives you extra coverage when you sit or lie down.
-
A secure fit in your size
Kischt has a high rise and a wide waistband. It covers your lower tummy and should feel secure without digging in. Sizes run from XS to 4XL.
-
Fabric and care
Kischt is soft, breathable nylon and elastane. It is light and stretchy, not cotton. Wash it after each wear and let it dry fully.
-
Price per pair
A pack can lower the cost of each pair. Kischt is $24.95 for one pair. It is $19.98 a pair in a 3-pack and $17.99 a pair in a 5-pack.
