Perfect fit, style and quality!

"Perfect fit, style and quality!"

mari k. (5/5)

pleasantly surprised

"Ordering from Oneill is always easy. Your sizing and fit are always accurate. I usually go with solid colors, but the wife liked the indigo blue floral so I tried them and was pleasantly surprised."

"O’Neill brand is the only board shorts I buy period. !! They look great , they stretch, and they last!! I surf and they are my go to board shorts 🏄‍:male_sign:!! Trust me they are the best!!"

Ralph D. (5/5)

Fantastic Swim-shorts!

"These are very comfortable, practical and nicely designed shorts."

Bozena K. (5/5)

Perfectly comfortable

"Very comfortable. My waist size varies by about 2 inches constantly so I got the larger size. I should have gone with the smaller size because they don't tighten up but they can loosen. Still satisfied, haven't fallen off."

Matthew T. (5/5)

Great colors

"Fit is comfortable, maybe a bit on larger size. Great pair of longer length board shorts."

Nathan Z. (5/5)

"One of my new favorites! The stretch is unreal and the size is perfect. Would definitely recommend."
