I've had the mcc for a few years and love it. The strap was just too short for my liking.
I got in touch with Mark and he is awesome he was a pleasure to talk too and made me a strap just for my needs and I love it it goes with me everywhere now because its so comfortable to carry i have never had such great customer service i will definitely be buying more from this American business.
Thinner than expecting, optimized super high quality
Not sure I needed XL length, especially in summer. Thinner width carrying strap than another essentials bag plus canteen carrier I have. Quality of Mark's is over the top. Dimensions are in description. Think the width of Centerline's is optimized. Liked the option of multi cam on webbing. Doesn't work as well as expected on some cheaper canteen carriers. Like to carry 2 or 3 canteens. No big deal. Plenty of uses, like G-roll!
