    Cold-weather riding starts here.

    Amassing a cycling wardrobe for the cooler months can be a daunting affair. With all of the different choices and possibilities you need to prepare for, it can also be a bit spendy. We don't always have room in the closet or the budget for all the precisely specialized gear that we'd like, so items like the Pearl Izumi P.R.O. Thermal Bib Shorts are among the first pieces of cold-weather kit that we pick up as the seasons change.

    The P.R.O. Shorts use Pearl Izumi's Thermal fabric throughout their construction. Thermal is recommended for temperatures between 40 and 60 degrees Fahrenheit, so it slots in as the cool-weather option in Pearl's clothing line. The difference between it and the cold-weather gear, PI Softshell, is that the latter incorporates wind and water resistant fabric. The Thermal fabric focuses solely on warmth and is more breathable than the Softshell. If you don't plan on riding in torrential downpours and you layer to protect against wind, then the Thermal is your ideal choice.

    Since they're shorts, the P.R.O. Thermals offer you the opportunity to wear them alone for cool days or add leg or knee warmers on a ride when the temperature drops. As one of our resident bike gurus puts it, "warmers afford you more real-time layering opportunities." If you overheat on a climb or during hard intervals, you can quickly slip them off. This is in stark contrast to full-length thermal tights, where the only option is ungracefully folding the bottoms up over your lower legs where they then flap about in the breeze.

    The shorts include Pearl's P.R.O. Anatomic 1:1 Chamois, which has a varied geography of light foam density ranging from 4 to 13 millimeters. Its seamless construction is unobtrusive with no abrupt edges or goofy little designs, just the right amount of support and comfort where you want it. In an industry that often thrives on extravagant design, the 1:1 insert is refreshingly minimalist and effective.

    The Pearl Izumi P.R.O. Thermal Bib Shorts - Men's are available in five sizes ranging from Small to XX-Large in the color Black.

    Covers a variety of needs...

      I've used these thermal bib shorts in winter with tights, but I especially love them during the cool Spring rides. They're definitely a favorite when the weather is under 60 degrees. Great quality, perfect chamois. The legs never rise out of place. You can't beat the price/quality comparison of the Pearl Izumi P.R.O. line bibs, especially on a Backcountry discount. I'm 5'5', 148 lbs, and wear Small. True to size.


      • Fit: True to size
      • Size Bought: Medium

      I have tried a few different brands of bib shorts, and I keep coming back to Pearl Izumi. They fit me perfectly, exactly as per their sizing chart. They are very comfortable as well. These were especially great when added with the customer service provided by Backcountry. All around awesome!

      Christmas gift; a little tight.

      • Familiarity: I returned this product before using it
      • Fit: Runs small
      • Size Bought: large

      My husband wears Pearl Izumi, Large, but found these shorts to be tight around the legs. I am getting him a X-large. It is just after Christmas, perhaps this accounts for the need of a larger size. :-)
      The Pro Thermal Shorts will be great for the Fat Bike in the snow.

      Winter Wonderland

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Large

      I love these thermal bibs! I ride/train all year round in the dry but cold Utah weather. These bibs have worked out well and are my favorite winter kit.

      I am 6 foot and 165-170 pounds. The Large fits well--I am right between the medium and Large. I could have gone either way.

      I have had these for two winter seasons now. The quality of construction is fantastic--they don't show any wear. I used them quite a bit when the temps drop below 60, and down to 40. Teamed up with knee warmers, leg warmers, or under tights , they give me lots of winter options. They are made from a wind cutting fleece lined material, warm enough, used with leg warmers, to ride down into the mid 40's when dry outside.

      The chamois is well done--I don't notice it, which is the way I like it. The leg length works well for me and they stay in place well enough to hold leg/knee warmers really well. The bib construction is comfortable.

      I would buy them again. Give them a try!

      best thermal bibs

      • Familiarity: I've put it through the wringer
      • Fit: Runs large

      Ive had 2 pairs of these that have lasted three winters of cold weather riding and commuting. They are now threadbare but have been worn a ton.
      1. they do fit roomier than traditional bibs but I think that makes them warmer
      2. they are long enough to have good overlap w knee or leg warmers
      3. chamois average, but has held up well
      4. fabric remains warm after repeated washings

      I'm really happy with these for what they are- thermal bibs that allow you to ride in sub 20 degree temps without freezing your nads off or wearing a second pair of tights. Comfortable into the 40's,, so you don't get hot on the way home from work. Ive owned panache, castelli and capo thermal bibs and I like these best. In general, I don't like PI bibs but these are great

      Good Functional Winter Bib Short

      • Familiarity: I've put it through the wringer
      • Fit: Runs large

      The thermal fabric is pretty warm. I like the functionality of using these with either knee warmers or full leg warmers. Only gripe, the chamois is not the greatest.

      Sizing , Chamois and Function All Good

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      I always return to Pearl because the medium product fits my 5'6" frame at 158 pounds reliably and the Pro Thermal shorts have evolved in good ways over the years at a good price point . I found the current 1:1 chamois to work really well on long rides this summer so was pleased to see it in new Thermals that I use for a late season event and winter riding in Steamboat . Since I always use leg warmers or tights with these
      thermal shorts , I found the extra length to nicely anchor warmers . Assos and Castelli have great details , but for basic cold riding , the Pearl Pros do the job really well .
