I have a pair, bought recently but have not worn hunting. I think they will be good in warmer weather down to about 45°f. Like the knee pad area and side pockets. Buy your size for correct fit. They may snag in thorny brush.
They are a great lightweight pant. Very similar to the Vahalla but with reinforced knees and pocket for knee pads. I wore these pants around AZ last November and I liked them a lot. If you like wearing knee pad inserts and want a simple lightweight pant the Ragnar pant fits the bill.
