Beyond Clothing A9 Alpha pants & shirt size XXL for both (equivalent to a Crye 38L-40L). These were issued to me for a mission in Northern Afghanistan and used only for one mission before returning stateside. They have never been used since and are in like new condition.
I wear a Crye 38L pant size for G3's and with the elastics pulled tight these fit me just fine. These items come from a pet and smoke free home!
