It seems like a good number of sports bras have the little plastic strap length adjusters on the back of the bra. Am so bummed that this one is the same way, otherwise I think it would be great. If you wear a heavy pack with it, they dig into your skin. The only alternative is going with a bra that has super wide straps , which dig into your neck. There needs to be more thin strapped bras without the plastic length adjusters on them.
