Hello, Do you price match? I found this item on Amazon for quite a bit cheaper.

Hello, Yes we do but it has to be a 2013 item from a Mares Dealer.
Question asked
on 5/25/2015
I'm 5'11" and 160 lbs. I often wear medium shirts. What size should I order with this rash guard. If it's not the right size for me, do I have the option of exchanging it? Do you have free shipping on returns? Also, what size do you think I should order for the matching trielastic shorts. I wear 30 to 32 waist in pants.

Hi there, I spoke with someone at Mares and they think (based on your measurements) that the Medium rash guard may be too short for you, so you should go with the Large. As far as the shorts, they think you would be a solid medium. Let us know if there is anything else you may need. Have a great day! Sincerely, Jamie, Customer Service

Hi, Thanks for your email. I think they run a little on the small size, a lot of people will go with a size bigger then normal. If you have any other questions, please let us know. Thanks Divemaster Chris
