KUIU Kutana pants for all hunting done over 45degrees for the most part. Kuiu has a side zipper to vent the hips/your boys and it's like having AC when you're sweating buckets ascending. Add a pair of zip off thermals and you have a your bottom half taken care of down to cooler temps. For cooler weather: Kuiu Pro pants, Sitka Mountain pants or timberlines with thermals. I'll add a pair of KUIU Chugach rain pants to cut the wind on cooler days and a pair of Kuiu down pants when temps really drop.
