Mackie Newton is the founder of Frank's Pants, a UK brand that makes washable leakproof underwear for men. He writes most of what you read on the Frank's Pants blog.

Why he started Frank's Pants

Mackie started Frank's Pants because of his grandad, John. John was a sociable, active man, and while he was living with prostate cancer he started getting bladder leaks. The products on offer felt clinical and embarrassing, and Mackie watched him quietly stop doing the things he enjoyed. John later passed away from prostate cancer.

Frank's Pants is the underwear Mackie wishes his grandad had had: pants that look and feel like normal boxers and quietly handle the drips, dribbles and light leaks, so they never stop anyone living life with confidence. You can read the full story in The Story of Grandad John.

Background

  • Studied Business and Management, then worked in corporate finance before starting Frank's Pants.
  • Launched Frank's Pants on Kickstarter, where it was funded in 56 minutes.
  • Finalist in the 2026 South East StartUp Awards, Innovation category.
  • Profiled by Underlines Magazine in July 2026.

How he writes about health

Mackie writes about the practical side of bladder leaks in men: why they happen, what helps, and how to get on with your day. He is not a doctor. Anything medical on the blog links to the NHS, Prostate Cancer UK or another trusted UK source, and he will always tell you to speak to your GP about any leaks, especially if they are new, getting worse, or come with pain or blood.

Frank's Pants are designed for light leaks, drips and dribbles. If your leaks are heavier, your GP or an NHS continence service is the right place to start.
