There are 3 fits for tops and bottoms: fitted, athletic and relaxed. Fit types are listed below and are indicated on each apparel item on newbalance.com:
Fitted apparel is snug against the body for range of motion with no extra fabric.
Athletic tops skim the chest, waist and hip for active movement, but are not tight. For bottoms, athletic cuts skim the hip and thigh and have rises that are close to the body but are not tight.
Relaxed fit tops drape loosely from the chest, waist and hip for total comfort and ease, and relaxed bottoms are generously cut through the hip and thigh, with rises that sit away from the body.
