Comfort and fit assured
Not my first pair of BOA half split. Great fit! Comfortable waist and a truly breathable inner liner means no rash.
Not built for carrying stuff, built for running after all thats what we are doing.

Amazing!
The black solid 3” half split is literally perfect. It comes with a black liner, not white for a sleeker combination. Doesn’t feel any different from the 1” shorts I’m retiring out of apart from racing.

BOA Running Shorts
This is my 4th pair of the 3” and I also have 1” shorts as well. I love the fit of these shorts and how they look.
