Climbing problems 101: the more you climb, the smaller your waist gets meaning these two pairs of pants are now too large for me.

Slate Grey Stretch Zion 32x30 (men's) - $35 (free shipping)

Blue (even though they look grey in the photo) Brion 31x30 (men's) - $35 (free shipping)

I have used them for about a year on and off however note that there are absolutely zero tears or defects with these pants.  They're in excellent condition and just don't fit anymore.  Most of my climbing has been in shorts.  Take them both for $65 (free shipping).
