How Black Diamond fits

Overall fit

slightly small

Black Diamond apparel is typically described as a technical, climber-athletic fit: trim through the torso with long sleeves and hem, so broader or non-athletic builds often end up sizing up while slim wearers find it true to size.

Tip: If you are between sizes or want to layer, take the larger size - most BD apparel is cut athletically slim.
