Colleen L.wrote a review of Icebreaker GT Run Rush Sports Bra - Women's on January 2, 2013
Familiarity: I've used it several times
This bra is supportive enough for running, and comfortable enough for sleeping. Merino is unrivaled for sport wear because of it's wicking and antimicrobial properties, and Icebreaker makes some of the best merino garments out there. A bit spendy but definitely worth it.
