Kate Hudson has teamed up with her brother Oliver to launch a new sports apparel collection for men as part of her affordable Fabletics brand, which she founded in 2013.

The actress called on her brother, also an actor, to act as a spokesman for the collection, titled FL2, which is being officially launched Thursday.

T-shirts, shorts, track pants and vests all form part of the range, alongside high-performance training gear featuring dri-fit technology. Training garments have been designed with hardcore workouts in mind, featuring mesh panels, stretchy materials such as cotton spandex and fabrics such as brushed jersey that can be worn in a non-gym context. The collection also offers a range of socks and underwear.

"I wanted to start a men's line because it was a natural progression," the actress explains, adding that the focus for the menswear collection was on comfortable high-quality fabrics, and lots of pockets for practical purposes.

"We designed FL2 with the modern man in mind," she told Women's Wear Daily (WWD). "My brother, Oliver, was my go-to for style and function feedback. As an athlete and father of three, Oliver embodies the man we're designing for; it made perfect sense for him to be the face of the brand."

Oliver highlights the transitional nature of the clothes from the sports field to everyday life, saying: "This is the stuff that you wear, it's just better. It has a little more style to it, it's comfortable -- I'd wear this all day long, to take the kids to school in, to go have lunch, and I just wouldn't get out of it."

There is also a strong focus on affordability, with prices starting at $29.95 and nothing in the collection exceeding $100.
