Is there a weight where light becomes UL.I know I'm heavy but I go slow and like to be dry.Most my over nights in FL.are light,but mostly do long trails of 3mth or more.Just wondering where you draw the LB. line?

Typically when your base weight (everything but the cloths you wear, your food, water, and fuel) weigh ten pounds or less then you're considered Ultra Light.

Not that it matters much though.
