The Simple Guide Pants have been discontinued and replaced by the Patagonia RPS Pant. More detail on the new version is included below and you may also want to check out the Best Hiking Pant for Women.
A pair of lightweight softshell pants that have articulated knees and are part spandex, the Patagonia Simple Guide is very flexible and water resistant. The combination spandex and polyester material cuts down on the breathability ever so slightly, allowing other pairs to edge ahead in that area.The Simple Guide has a streamlined, comfortable design with just the right features for hiking and climbing, such as durability, weather resistance, and a zippered thigh pocket.
If the most important feature in your hiking pants is for them to move as you move, then the Patagonia Simple Guide Pants are a wise choice. These are the best choice for long alpine climbing approaches since they double as an excellent climbing pant and hiking pant. The Arc'teryx Palisade Pant - Women's is also extremely comfortable and flexible, though they are not as durable and are more expensive than the Simple Guide. If you are looking for the most ideal pant for a long hiking or backpacking trip, the lighter Marmot Lobo's Convertible Pant- Women's has the best combination of attributes. They convert into three different pairs of pants and breathe better than the Simple Guide pant.
