Anyone that has done any surfing knows that chafing is one of the fastest ways to ruin your day.  The good news is these shorts deliver on that front.  Minimal seams and great fabric mean you can stay out all day swimming, snorkeling, or surfing without issue.  Frankly you forget your wearing them.
Like:  Comfortable, good design on the string ties, dries quickly, great price for what you get.
Dont Like:  More a caution, don't buy these one size bigger and expect them to cinch down.  The size listed is the size when the strings are cinched almost as far as they can go.  Buy your exact waist size or a little smaller if you don't want to lose these in rough surf.
