The short version

ONDR makes a good leakproof product and, like us, it is a modern brand rather than a medical one. Its men's boxers hold a fair amount and use an interesting beechwood and algae liner. Credit where it is due.

But there is one very practical problem for you: ONDR ships from the US. For a UK buyer that means slower delivery, potential import charges, currency conversion, and a genuine headache if you ever need to return something. A leakproof pant you cannot easily size-swap is a gamble.

Frank's Pants is British. UK sizing, UK shipping, UK returns, prices in pounds, and a 60 day guarantee that actually means something because we are here. Plus three styles instead of one.

Where ONDR is genuinely good

  • Solid single-tier product. Decent capacity and a thoughtful, sustainable liner material.
  • Modern, non-clinical brand. Like us, it treats customers as people, not patients.
  • Established DTC name. Good reviews in its home market.

Where Frank's Pants wins

  • You are in the UK, and so are we. No import charges, no three-week shipping, no returning a parcel to America. Order today, wear it this week, swap the size in a couple of clicks if it is not right.
  • Three styles, not one. ONDR is essentially a single leakproof boxer. Frank's covers light drips (The Active), light leaks that come and go (The Everyday) and long days when you want to swap in a fresh pad (The Ultra), so you buy for your real need.
  • Made with recovery in mind. The Ultra's swappable pads were designed with men recovering from prostate surgery in mind, for the lighter leaks and long days that come with it. That is where Frank's started.
  • A guarantee you can use. 60 days, UK based, no transatlantic faff.
