"The best pair of shorts I have ever owned!!! Just purchased another pair!!"
"I love these Red, White & Blue shorts with stars. Perfect for the 4th of July! Chubbies is all I wear, they are comfortable and look great on me always. I’m the cool guy in my Shorts, always."
"These are ridiculously comfortable. I wish I could wear them as everyday shorts. The built in liners feel amazing. The look is fantastic."
"Love love love these shorts! They are great for swimwear and activewear. Great liners in the shorts. Have received a lot of compliments on these shorts. I love all Chubbies wear in general!"
"Not the biggest fan of these. Pockets aren’t great. I almost lost my wallet with these shorts and the compression liner is loose. It falls way down past the shorts because the compression is loose. Very patriotic though."
"Did a full weeks worth of running in South Carolina for some events, temps in the 90’s and humidity near 100% sweat was like a river, these held up well, no chafing and they dried over night."
"The American flag theme puts out the summer vibes"
"So comfortable and stylish only shorts I’ll ever wear"
"My grandson loved the training shorts"
