The clothing company is moving from 50 Island St., where it occupies five floors. The price of lease is undisclosed, but a source tells GlobeSt.com that comparable property in Haverhill averages $6 per sf. The tenant was represented by Tyler Ewing and Brad Spencer from Grubb & Ellis, while the owner, Suffolk Advisors LLC, was repped by Greg Klemmer and Ted Geary, respectively principal and associate at Klemmer Associates LLC.

"Southwick's former facility was on five floors in an outdated facility," says Ewing in a statement. "The move from Lawrence to Haverhill puts the company all on one level in a relatively new, state-of-the-art facility. The move still keeps more than 300 jobs in the region at a time most companies are outsourcing overseas."

Southwick was recently purchased by Retail Brand Alliance, which also owns Brooks Brothers, a high-end apparel company. Southwick primarily manufactures suits.
