Why People Love It: If you're looking for a high-performance piece for an affordable price, this is your match. It also comes in a four-pack! It solved this reviewers issue for support. "I have a hard time finding sports bras that are supportive, and this bra was a pleasant surprise! It fits, lifts my breasts, and provides just the right amount of coverage and protection. My breasts are heavy, so they tend to sag in bras that don't have underwire. But in this bra, they don't sag at all!."
