Not what you want for heat:( Solid pants however.
I have three pairs of original arbortec ul pants and they are snow pants with a vent. I have one( now two pairs) of Clogger Ultra and they are the only pants I can climb above 75 degrees without getting g swamp crotch. I used my new Arbortec Vented today and was very disappointed. Swamp crotch by 11am. Was soaking all day. Temp. and humidity today mattered, but pants are heavy and ventilation does not work well to create a cross breeze which make Clogger Ultra far better and n my opinion.
Workable in 80F+ and Climbable
Tall is definitely tall, 34" inseem maybe more. Good for boots. More room in the hips compared to clogger zero and a higher back with more hip venting. Thighs are a little looser but I like that. I do think the knee pad area is 1/2" too low but it covers my knees. I could see a super skinny thigh person liking clogger zero a bit more. My rear is too large from years of squats though. Large waist was closer to 36-37 at the middle setting, but could cinch to 33'ish, not sure how much it expands, probably to 39-40. Overall I like them. Took me 20+ years to finally get saw pants. Happy to have found these. Bonobos is the only pants brand that fits me if that helps you understand the leg thickness ???? Kinda wish there were saw fore-arm guards with how much my forearms get torn up sometimes climbing certain trees - just on the bark / vines. Side note... get the arbtech suspenders in the same order... dont be like me and have to come back.
