"Solid & Striped Sport's fun activewear will be my go-to this spring. I got to test out the Trek Belt Bag Leggings ($128), which feature a high waist and comfortable, lightweight fabric. I love that these leggings also include matching belt bag, which is perfect for holding my keys and hand sanitizer when I walk my dog or go hiking. They're the first leggings I've ever had with a matching belt pouch and now I want every pair of leggings I own to have a corresponding bag. I'd highly recommend these to any fitness instructor who wears a mic pack as the belt bag is the perfect place to store it." – GF
