The RR Billy Goat pants are great for casual wear, but will be used primarily for hiking. Great for warm weather, they breathe well and have front pocket liners made of mesh material. Rear pockets are lined with the same nylon material and have small Velcro closures Only 13.35 oz (size 34 x 30) on... Read More

    I find the Bill Goat fabric to be very comfortable. The sizing was right on. Love these pants.

    These are great hiking pants...very comfortable, durable and dry quickly. However, if you're looking for a pair of pants that you can wear on travel (like at museums and decent restaurants), these probably aren't the right answer. The legs are very baggy and don't fit in very well with current European fashion trends (we live in Oslo right now).

    I can't say enough about these pants! They fit just right, they are super comfortable, lightweight, durability is just as advertised. Truly a five star product!
  • Verified Buyer Reviewed by HikeTeach from Missouri on Wednesday, June 10, 2015
    Love the Billy Goat Nylon. Lightweight, breathable and wicking. Very well made. The articulated knees and gusseted crotch are well designed. Two reasons for 4-star rating:

    1. The sizing is off. I usually wear a 33 or 34 inch waist. The 36 inch waist in these fits like a 34.
    2. Only two front pockets and two rear. A cell phone pocket would have been nice.

    For the price with an STP coupon, you can't beat them even with these two negatives.

    I was a little concerned seeing people say these run small but ordered my normal waist size and it was perfect. I was impressed by the quality of the materials and cut of the pants. They are loose enough in the legs to be comfortable and the knees are shaped and spaced to allow more freedom of movement. I was looking for a alternative to uncomfortable jeans. These are made of a durable nylon material and a little heavier material than some of the other nylon material used in similar pants. The styling is classic and can be used in town and doesn't look like baggy or floppy.

About Royal Robbins

By the late-1960s, veteran Yosemite rock climber Royal Robbins and his wife Liz had grown tired of wearing cutoff jeans on the crag. At the time, apparel designed specifically for outdoor adventure was virtually non-existent. After years of wishing for something better, the couple finally decided to create their own, starting with a pair of climbing shorts called the “Billy Goat.” This was the beginning of Royal Robbins’ clothing revolution. Today, nearly 50 years later, Royal Robbins outdoor clothing is as rugged and reliable as ever. When you buy a Royal Robbins sweater or shirt, or a Royal Robbins pair of pants or shorts, you can bet it will fit great, whether you’re climbing in the Sierra Nevadas, camping in the backcountry or relaxing in your own backyard.
