"I already owned the 5.5 inch version of the athletic shorts which is a bit long for me. When the 4 inch version went on clearance, I picked up two pairs. I can honestly say that I prefer the shorter pair. Another garret product from Chubbies!"
"I’m not sure I can go to any other shorts after these! I use them from everything like pickleball to long 6+ miles runs. They hold my phone and keys without causing any flopping or anything. I’ve used them several times at the beach on a whim when I didn’t have swim trunks too."
"These are the perfect running shorts! They have the right amount of pockets. 2 drop, 2 in the liner, and a zip on the back. The liner pockets fit my S24 Ultra without a case on, and make it super easy to run with my phone. I can't even notice it being there!"
"I've ran in these multiple times, and they are great. I suggest buying them on sale because that's a fair price. I like the fun colors, but they didn't make me any faster."
"Fits great!"
"Bought them to use for 5K races. They fit great. Run a little bigger than anticipated but not bad."
"The ultimate training shorts fit perfectly and are very comfortable. I use them for everyday gym use and never have an issue. They are lightweight, look great, and are perfect for working out or everyday wear."
