This was brought up by The One Show hosts Alex Scott and Roman Kemp, leaving Patrick lost for words.
When Alex asked him about the possibility of reintroducing Y-fronts as a challenge, Patrick started to respond but quickly stopped himself, joking: "I can't say."
However, he did confess: "I'm a big fan of the Y front," describing them as "comfy" and "sexy". He added: "You've never been more comfortable than the Y-fronts," reports the Express.
Referring to his ethical clothing brand Community Clothing, Patrick continued: "Community Clothing, we do normal pants and boxers which is what everybody wears but I'm like, let's get the Y-fronts back."
In addition, Patrick hinted at an upcoming challenge centred around reusing and recycling fabric, insisting it's a "great" one.
He revealed: "At some of these big festivals, 40-50,000 tents get left behind. When we were researching this challenge, I Googled how much you could get a tent for and on a cheap website you could get one for £5.70.
"Tents have essentially become single-use plastic, they are 100% plastic, you could use it for a weekend and leave it behind. But where does all that fabric go?"
He continued: "Our contestants made some amazing stuff. They have to make a festival outfit out of the tents left behind at last year's festivals."
Discussing the diverse backgrounds of the contestants on The One Show, Patrick shared with hosts Alex and Roman: "They're an amazing bunch with a brilliant eye and just the loveliest people."
This update follows the introduction of new challenges for the contestants on The Great British Sewing Bee during Korea Week, which paid homage to the country's rich fashion and textile heritage.
Patrick hinted at future excitement, revealing to RadioTimes.com: "There's another great one next year. It's a really good set of challenges.
"I really enjoy the international weeks because I really enjoy finding out about the kind of ins and outs of their culture and their clothing traditions," he expressed to the outlet.
"And I think the audience really like it too. We've had some amazing ones over the years."
The Great British Sewing Bee is broadcast on Tuesdays at 9pm on BBC One and iPlayer.
