If you’ve been curious about period panties — how they actually work, whether they’re worth it, and where to find them in Sri Lanka — this guide answers everything. No fluff, no sales pitch. Just honest answers.
What are period panties?
Period panties are absorbent underwear designed to replace or back up your usual period protection. They look and feel like regular underwear, but the gusset (the inner lining between your legs) is built with multiple layers that absorb menstrual blood, lock it away from your skin, and resist leaks.
Think of them as reusable pads — but built directly into your underwear so there’s nothing to stick, adjust, or throw away.
How do period panties work?
Most period panties use a 3-to-4 layer system in the gusset:
- Layer 1 — moisture-wicking top layer: Pulls blood away from your skin so you stay dry and comfortable.
- Layer 2 — absorbent core: Locks the fluid in. High-quality pairs can hold the equivalent of 2–4 regular pads.
- Layer 3 — leak-proof barrier: A thin waterproof membrane that stops anything from soaking through to your clothes.
- Layer 4 — outer fabric: Soft, breathable fabric that looks like normal underwear.
The result: you bleed freely, the underwear handles it, and you stay dry, comfortable, and confident — all day or all night.
Period panties vs pads vs tampons
| Period Panties | Disposable Pads | Tampons | |
|---|---|---|---|
| Reusable | ✅ Yes — lasts 2+ years | ❌ Single use | ❌ Single use |
| Comfort | Feels like normal underwear | Can bunch, chafe, and rustle | Comfortable when inserted correctly |
| Leak protection | High — full-coverage gusset | Depends on placement | Can leak if not changed in time |

A Sri Lankan woman who spends LKR 500–800 a month on disposable pads spends up to LKR 9,600 per year. One pair of period panties from period.lk costs LKR 3,500 and lasts 2+ years with proper care. The math is simple.
Who are period panties for?
- Women who get skin irritation or rashes from disposable pads
- Anyone who leaks overnight no matter what they use
- Women with a light flow who want something simple and comfortable
- Active women who need backup protection during exercise
- Anyone trying to reduce their plastic waste
- Teenagers getting their first period — no insertion needed, easy to use
How to choose the right period panties
1. Pick the right absorbency
Most brands offer light, moderate, heavy, and overnight options. If you’re unsure, start with heavy absorbency — you can always layer with a tampon or cup on very heavy days, and use them solo on lighter days.
2. Choose the right style
- Boyshorts / high-waist: Maximum coverage. Great for heavy flow and overnight use.
- Brief / hipster: Everyday comfort. Works for light-to-moderate flow.
- Bikini: Less coverage, better for lighter days or as backup.
3. Get your size right
Period panties should fit snugly — not tight. A loose fit means gaps at the legs where leaks can escape. Use your usual underwear size as a starting point. If you’re between sizes, size up.

How to wash and care for period panties
- Rinse immediately in cold water after removing. Cold water — not hot. Hot water sets blood stains.
- Hand wash or machine wash on a gentle cold cycle. Both work fine.
- No fabric softener — it clogs the absorbent fibres and reduces effectiveness over time.
- Air dry only. Never tumble dry or iron. Heat degrades the leak-proof membrane.
With proper care, a good pair should last 2–3 years of regular use.
Common questions about period panties in Sri Lanka
Are they discreet to order?
Yes. All orders from period.lk are shipped in plain, unmarked boxes with no branding visible on the outside. This matters — we know it matters.
Can I get cash on delivery?
Yes. We offer cash on delivery island-wide across Sri Lanka. You pay when the package arrives — no need for a card or online banking.
Do they smell?
No more than regular underwear. The moisture-wicking top layer keeps blood from sitting against your skin, which is what causes odour. Rinse promptly after use and you’ll have no issues.
Can I wear them swimming?
Period panties are not swimwear — water enters the fabric freely. For swimming, use a tampon or menstrual cup and wear period panties before and after as backup.
