Here's the reply from their return department after a week of radio silence and several followups. These pants split on my first ride - clearly defective.
But I guess its my fault for trying out my size before ordering a larger size to compensate for a defective product. "Thank you for contacting SwimOutlet.com! I am sorry to hear that the seam split on the Louis Garneau Men's Pro 9.25 Carbon Tri Shorts - Red/Black - Large you ordered. I also understand that you feel you need a size XL as well.
Unfortunately, we will not be able to accept the Large back for a refund, because it seems to be more of a sizing issue than defective merchandise. I hope this information is helpful to you. Have a great day!
Sincerely, Brittany Customer Service" At least Brittany told me to have a nice day, wasn't that great. SwimOutlet runs a shady return operation - BEWARE!
