You might not love riding in the rain, but if your training schedule forces your out in it very often you need to pick up a pair of Pearl Izumi P.R.O. Barrier WXB Cycling Pants. These pants are breathable, windproof, waterproof and they have kept me dry in torrential downpours on days when no one in their right mind would be outside.
Pearl Izumi P.R.O. Barrier WXB Cycling Pants are made of a three-layer thermo-regulating laminate fabric. This breathable fabric is 50 percent polyester, 32 percent nylon, and 18 percent nylon. You will find abrasion patches in high wear areas that should keep you from ripping these pants like I’ve done with cheaper rain pants. These pants are sturdy enough for both road and trail use. Since riding in the rain almost always means low-visibility, these pants have 360° reflective elements that really stand out when light hits them. The asymmetrical leg cuffs should keep you from getting your pants caught in the crank. There is also a side adjustable waistband to help you get a good fit. All of the internal seams are taped and totally waterproof.
We need to talk about the fit around the ankles for a moment. These pants have nine-inch waterproof ankle zippers so they will fit over cycling shoes and shoe covers with ease. However, there is not enough room to wear these pants with the cuff on the outside of heavy winter boots. This could cause a problem if plan on wearing these pants as a winter shell—they will do great most of the time, but if you have to walk through deep snow then you could find yourself with wet feet after a while.
If you are looking for the perfect waterproof shoe covers to go with these pants, I would suggest the Pearl Izumi Elite Barrier MTB Shoe Cover. If you need warm winter shoe covers, I would suggest the Planet Bike Blitzen Windproof Shoe Covers.
Pearl Izumi P.R.O. Barrier WXB Cycling Pants have a retail price of $225, but they are available on Amazon.com for around $160. These pants will probably be one of the most expensive pieces of cycling wear you will ever buy, but they should give you many years of use. This product comes with a lifetime warranty against defects in materials and workmanship. In case you were wondering, the P.R.O. in the name stand for Performance Race Optimized.
