The Swiss M83 pattern, colloquially known as "Alpenflage", is drippy.  Does the red really help as a functional camouflage?   Yes. BUT! Only during a New England fall when you're hiking with a Pumpkin Spice Latte, you basic bitch you.  

Only available at the moment in Large (52).  This size on a 5'10", 200lb warehouse monkey is a little tight in the shoulders getting it on (he works out and ovbiously huge and jacked and tan), but the shirt wears well and comfortably with just a t-shirt underneath.  Would consider this size in between true a Medium and Large.  

Available in Grade 1 (Like new, no fading, like the image) or Grade 2 (some wear and faded).
