“I purchased a pair of Sonic Boom XLs primarily for outdoor running in the winter, both to keep warm and for additional visibility when it's dark. If the reflective stripes happened to make me look extra fabulous as well as extra visible, well, that's a plus; it's a scientific fact that fabulousity = increased velocity. Anyway. I am happy to report that they are extremely comfortable, flexible, and they they kept me well insulated on 5 and 10k runs. As a tall human, I find it tricky to find garments that fit, so it's great to be able to report that the XLs did.”
