The Simple Guide Pants are now discontinued and have been replaced by the Patagonia RPS Pant. You will find more detail on the new version included below and you may also want to check out the Best Hiking Pant for Men review.
The Patagonia Simple Guide Pant is an excellent cool to cold weather climbing pant, and it earns the title of Top Pick for its unique "in-between" weight that shines in a wide variety of temperatures and conditions. Depending on the temps and conditions that you normally climb in, this may be the best pant for you in the review.
Without layering, this pant is good by itself for active use in temperatures of roughly 30-70 degrees F, and with a pair of long underwear, the temperate range could easily go down to 10 degrees F. If you are looking for a pant that is better suited to warmer weather, consider the Patagonia Rock Craft Pant instead. The rock craft pant breathes better, is lighter, and is cut tighter for use without layering.
If you are looking for a good quality pant at the lowest price, consider the Prana Stretch Zion pant, but also consider whether the cut and features of the rock craft pant might be worth a few extra dollars over time. If you are looking for something extra durable, consider the Mountain Hardwear Piero pant, or if you don't need the breathability and quick-dry qualities of a synthetic pant for your climbing use, consider a super-durable cotton canvas Arborwear or Carhartt type pant instead!
The quality in design and workmanship in the simple guide pant is evident, and it has been made to be as simple and functional as possible. You will find yourself grabbing this pant for a myriad of uses: mountain biking, cross-country skiing, and hiking, as well as all types of climbing, big wall, multi-pitch, or cool weather cragging and bouldering. We believe that this pant is a home-run.
