Wow - these tights are really in a class all their own. I have many pairs of tights - CWX, Asics, Salomon - and use them for nordic skiing (primarily skate), trail/mountain running, as well as both road and mountain biking. I have found that each tight - by manufacturer as well as by the tight its... Read More

    This is the 3rd generation of Amfib I've purchased. Fit is MUCH tighter than the others (which I still own and wear). I fit a large in other Pearl shorts/bottoms but with this generation of the Amfib I had to go with a large. I'm 6'3 with a 33" inseam and the XL was a long fit. These are definitely sized for the tall lean athlete. The fabric is elastic and stretches but a more muscular build will be challenged to fit into these.

    The material does NOT slide easily over base layers. If you go with a base layer definitely use a slick fabric.

    These are by far the warmest tights I've ever owned. I use 'em for bicycling and I'm mostly on the road. For me, without a base layer, the temp limit is about 20 degrees. Below that I'd want to add another layer. Note this is on an early morning ride at sunrise so on a sunny winter day I'm sure I would be comfortable in cooler temp's.

    A few nice features to highlight:
    The picture doesn't show how the tights cover the top of the shoe - a very nice touch to help keep the feet warm. The ankle zips are welcome as is the elastic draw string.

    One observation is that the tights made noise on the initial rides as they rubbed on the leather bicycle saddle. This has dissipated after a few hundred miles. Never a problem and no signs of wear to the tights nor the saddle, just a note.

    After reading over the reviews, I decided that large size would be ideal (I am 6'4" and 210 lbs.) but gave the XL a try, because some of the reviews had said that they run small (and because that was all that was available)l. When I tried them on, the waist fit (with a little cinching) and everything from the knee down felt fine, but the quads were very baggy. I have relatively skinny legs, and even considered keeping them, as they still would have performed well for snowshoeing or winter hiking, but since I really wanted them primarily for running, I am sending them back. If there was a large, I may have exchanged them, but I have to agree with some of the other reviews that these things feel more like a wetsuit than traditional winter running tights. They are serious tights! As a bit of a gear junky, I was a bit in awe of how much protection from water and cold they offered. I even wondered if I could have skied in them.

    Anyway, sizing is very important, as they aren't very stretchy, so under or over-sized are equally limiting. If you are like me and are looking for running tights that you can use in 25-40 degree temps, these are probably overkill.

    These are listed as running tights, but I have been using them all winter for cycling and they are outstanding. They are extremely tight, so they're probably not for everyone. I'm 6'0", 185 and the L takes a bit to tug on, but they are warm and extremely comfortable..

    I posted a review about 2 years ago on how great these were. After a week of working outdoors in 0 degree temps., I have changed my mind, I think they are better than great. Not once did I get cold and these tights were a big part of the reason. If you can get these in your size buy them. If a size large is available again I am going to buy a second pair just so that I will always have plenty.

    I bought these mainly for winter biking. They kept me warm on a nice ride in 20 degree weather. These work great with a pair of chamois underneath for riding comfort.

About Pearl Izumi

Before Kinji Shimizu created the first Pearl Izumi cycling apparel, he spent nearly seven days a week on his bike delivering 90 pounds of clothes to customers. He frequently pedaled 38 miles a day. Years later, after his son received a special Italian-made cycling jersey, Kinji was inspired to start creating his own using the best fabrics he could find. The result soon evolved into the Pearl Izumi brand. In the five decades since, the company Kinji founded has continued working hard to make the best gear possible for dedicated athletes and weekend warriors. From incredibly lightweight Pearl Izumi shoes to sleek, comfortable Pearl Izumi running apparel, few other brands have the same relentless drive toward innovation as Pearl Izumi.
