FAQs
Compression vs encapsulation?
Compression flattens the bust against the chest. Encapsulation has individual cups that hold each breast separately. D+ cups need encapsulation for proper support.
How tight should a sports bra be?
Snug, not constricting. Two fingers should fit between band and ribs. Cup should fully contain bust with no spillover.
