First of all I want to say thank you guys for everything all of your products are top notch and thank you for fulfilling that order so quickly however I opened my pants up this week to try them on and the medium size is a little snug and I have two pair of breathflex pro in medium I don’t ever wear long Johns or thermal underneath and I believe that’s the problem so I was hoping I can send these un worn non protective climbing pants back in exchange for tree next size up so they’ll be more user friendly for me and my long Johns during these cold seasons when I’m bundling up let me know what I need to too the pants have never been use or work just tried on I have original box everything to send so you guys can see
