High-end men's golf attire company Greyson Clothiers is opening a store in downtown Detroit and teeing up plans to eventually move its base to the city.

Greyson, which specializes in golf clothing, will open a 3,500-square-foot shop Wednesday on the ground floor of the First National Building as a pop-up through Aug. 31, Greyson spokeswoman Adrienne Cass said.

It will be the Hawthorne, N.Y.-based company's only brick-and-mortar retail store in the country, launched in tandem with the Rocket Mortgage Classic PGA golf tournament that is scheduled for the end of June at the Detroit Golf Club. Once the pop-up is done, the company plans to open a permanent flagship store in Detroit — either at the Bedrock LLC-owned building or elsewhere in the city. The long-term plan is to move Greyson's 20 or so full-time employees to the city.

"My heart never left Detroit," Greyson owner Charlie Schaefer said. "We will be flowing product into the store that doesn't exist anywhere else."

Schaefer grew up in Birmingham and moved to New York City, where he worked for 13 years at Ralph Lauren Corp. Under the wing of the company's namesake founder, Schaefer was elevated to senior vice president of design before breaking out on his own in 2015 to start Greyson.

The company mainly sells its products wholesale to 700 stores and pro shops across the country, including in Michigan. It opened an experimental store in Florida in March 2018 and closed it about a year later. Schaefer said it was "not destined" to last longer than that.

Greyson sponsors more than half-dozen golfers on the PGA tour, including Luke Donald, Kelly Kraft and Morgan Hoffmann, who has committed to playing the Rocket Mortgage Classic.

Schaefer said he's had his sights on Detroit since last year, when he found out the city would be hosting its first PGA tour tournament. He made a few phone calls and eventually landed a deal with the tournament's sponsor Quicken Loans Inc. to be one of several clothing vendors for the tournament.

"It made a lot of sense with all of that to have a physical space here as well," he said.

The Detroit store will carry Rocket Mortgage Classic-branded apparel. It sells polos, sweaters, outerwear, shorts and trousers, as well as accessories. It will also offer Garrett Leight eyeglasses and Res Ipsa shoes. Schaefer said the average spend is about $250 per customer. Polos start around $90, cashmere sweaters start at $250 and hats are usually around $40.

The store will also feature a putting green and an OptiShot golf simulator, where patrons can play holes from the Detroit Golf Club. During the tournament, on the grounds of the actual course, the company expects to sell equipment from its 30-foot 1971 Airstream trailer, which will serve as a mobile showroom for its products.

Schaefer said 10-12 employees will be working in Detroit, at the new store and tournament. Its plan for a permanent location is not solidified. Cass said the company wants to contribute to the economic development of downtown and aims to bring jobs to the city.

A public grand opening of the store downtown is scheduled for 11 a.m.-2 p.m. May 30 with giveaways and free food and drinks planned.

Schaefer declined to say how much is being invested in the store, or the terms of his agreements with Bedrock and Quicken Loans. He said he is handling design of the space.

"I've got big plans for the store, and I do see longevity," Schaefer said.
