I've tried lots of different gloves, I wear'em on pines but I always end up tossing them if I wear them when I'm moving around a canopy. It's not a he-man thing, it's about sensitivity... I'm still a rock climber at heart.
Now, as for underwear, I never wear the stuff unless it's really cold... and that IS a he-man thing.
I go through split tails, not because they wear out so much as I like to splice so I've always got new ones in the bag.
I've gone through lanyards, 4 or 5 in the last year. I'm on my third rope this year, I've had bad luck with ropes and polesaws. I still use the first one because it's a ninety footer now and it's a great length for pines and mid-sized oaks.
I just busted my first forestry kit and it looks like I might could use an MCL replacement in my left knee.
