Worn by 48,000+ Gentleman Across the United States

Where It Began
Gentlemen Prime Boston began in 2013 with a simple idea between two friends, Daniel Verne and Michael Loyd. We believed a man’s wardrobe should reflect who he is becoming steady, intentional, and confident in his path.
What started as a small selection we personally chose slowly became a place men trusted when they wanted pieces selected with purpose.

Brotherhood
Recently, our story took an unexpected turn. Michael suffered a serious accident that left him severely injured and now relying on a wheelchair.
Keeping the store running suddenly became much harder than we ever imagined.
To help us continue forward, we introduced our SPRING STYLE EVENT | Up to 50% Off a temporary event where many pieces are offered at reduced prices until the event ends.

Built for the Man Becoming
Gentlemen Prime Boston was never only about clothing. It was always about the man building his life step by step and choosing pieces he can rely on.
Today, every order means more than ever. When you choose Gentlemen Prime Boston during the Spring Style Event, you help keep alive the store two friends started in 2013 and the story we are determined to continue.
