Product Update - LP01
Bought our underwear before? Here’s what we changed.
We took what we learned from our earlier designs and built our fastest-absorbing MaxProof yet.
We didn’t start over. We started from what you told us.
If you’ve bought from us before, thank you. You’re the reason DesignComfort is still here — 200,000+ women since 2019.
Our original MaxProof did its job for a lot of women. But every review and email taught us something, and we kept asking one question: what would make the next pair better?
MaxProof FlowLock™ 2.0 is our answer. It isn’t a fix for a problem with the original — it’s the next step.

- 2026MaxProof FlowLock™ 2.0 — our biggest redesign yet.
If you’ve worn leakproof underwear for a while, some of these may sound familiar
Not everyone runs into these, and many women are happy with what they wear today. These are simply the things we set out to improve.
Four changes, one at a time
Faster absorption
This is the change you can see in the side-by-side test further down.
More capacity
Quieter construction
Less spreading toward the leg openings
Results vary with the size of a leak and with fit, which is why you get 100 days to try it.
Our original next to MaxProof 2.0
Same cup of water, poured at the same moment. Real footage, no speed-ups.
The original is light gray and 2.0 is charcoal, so don’t judge by the dark spot. Watch the shine — water sitting on top reflects light; water that’s been taken in doesn’t.
Original vs. MaxProof 2.0

From women who’ve worn our earlier pairs
Out of all the different ones I have tried, including earlier pairs of yours, these are by far my favorite!
A big improvement over its predecessor… much more comfortable.
They feel like luxury underwear and still do their job. I am hooked.
They work so well & don’t make me feel like a grandma, haha. They look like regular underwear and are comfortable with good protection.
