19 up-and-coming athleisure brands that aren't Lululemon

Lululemon has been poised for a comeback. Wells Fargo analysts have said that it has been improving its design, production, and supply chain.

But the company faces steep competition.

Over the past few years, the athleisure market has become incredibly popular. Everyone is trying to cash in on it, from Dick's Sporting Goods to Nike.

And Lululemon still has its troubled history. Customers were furious when founder Chip Wilson commented in 2013 that his pants didn't work for everyone.

These companies could make it harder for Lululemon to hold such a large portion of the market share.

Some companies, like Gap's Athleta and Nike, are huge. Others are more niche brands that can be ordered online.
