M's Lightweight Hunting Shirt Long Sleeve

Woodland

Great shirt but order a size larger than you usually would

I own several short and long sleeve in multiple colors. These are my go to shirt for going to the office, going on a bike ride or hike or any other outdoor activity in addition to upland hunting. I hope they continue to roll out other non-camo colors such as a near white (I think it was called bone) and a blue one as well. I wear one of these at least 5 days a week.

This is a good shirt and I like the patterns offered. But can anyone tell me why there's a lone orange button on it?
