"I have wanted these in 5. 5 in since they made them about a year ago, while the 5. 5 hasn't been reintroduced I went for the 4 in which are great too, you just like what you like. Other than that, great shorts as always, the ultimate shorts feel amazing. I do wish the pockets could be free instead of sewn at the outer seem. Makes everything fall out of your pockets."
"Great workout shorts! The liner keeps everything in place and has good flexibility. The phone pocket is a great addition. Bright fun prints."
"Best choice for CrossFit. No slipping or pulling up. Own around 4 of this and always get complements and super comfortable"
"Awesome shorts like always with a great pattern and colors!"
"These are great! The other pair I have is the reason I cam back for more Chubbies. Quality stuff!"
