Pearl iZUMi Men's AmFIB Tight Reviews

Customer Ratings:

I use these tights for nordic skiing, cycling, and running. It should be mentioned that this version of the tights doesn't have the chamosis pad, which I didn't want for my intended uses. They are warm, windproof, and water resistant. The coldest I have worn them skiing without any layers on underneath is 0 degrees, and I was fine. If it got any colder though, I would put on another tight layer underneath. The fleece on the inside is soft and comfortable. The fit and construction is fantastic. Pearl iZumi is a great brand with a lifetime warranty. These tights are expensive, but well worth the investment for their versatility. I highly recommend them.

A spectacular COLD weather tight from Pearl that can be used for both running and biking (just wear your favorite bike shorts under them). When the temp dips below 40F degrees and gets windy you need this tight. Above 45F degree these tights get pretty warm, but still breathe. I have worn these on a handful of 30F-50F degree rides and not once have my legs gone cold from the temperature or windchill.

Pros:

Great windproof front panels. The front panels are a somewhat neoprene-like fabric that is slick and stretchy. Pearl claims they are also water resistant which I believe, but have yet to field test.

Very warm/comfortable thermal fleece fabric lining on the inside. It wicks moisture nicely! I have soaked through these things with sweat and have never felt chilled.

A higher cut "tail" in the rear to protect your lower back as you are bent over riding

Zippered ankles

Cons:

Fitment is a little funny in the "private" area. I am 5'11" 160lb and bought the Medium. The fit is spot-on around the waist, thighs, ankles, and overall length. But, due to the thickness of the neoprene fabric, there seems to be almost a flat spot in front of the family jewels where the material doesn't conform to the contours of the body. Not a big deal, purely cosmetic. Just thought I'd mention it because it might look funny when running.

Thick material if planning on running. I am not saying you can't run in them but Pearl makes a great thermal running tight called the Infinity Thermal Tight that affords a little more freedom of movement.

No pockets! Not even a little fabric one on the inside... ugh.

Overall, these tights perform perfectly on the long, cold, windy rides.

quality construction and quite warm. these are for 45 degrees and under riding temps. wind-proof and comfortably snug. only problem is in the inseam length. i ordered a medium (i'm a 30" inseam/32 waist) and they are too long, causing some bunching-up around the ankles and knees.

Honest reviews on Pearl iZUMi Men's AmFIB Tight

I've worn these down to very low temps and they deliver. The useful temperature range is also surprisingly wide: probably you can go from about zero all the way up to 35 degrees F with these and feel fine. For lower temps, add long johns and you'll be burning up. (I wore some medium weight long johns with these at a windy 9 degrees F and I was warm even standing around...).

They are remarkably waterproof/resistant (fyi, amfib is a shortening of "amphibian" I think).

Very comfortable.

Not sure what other people mean about sizing. I just barely fit in my size L Pearl Izumi Elite Thermal tights... but these Amfibs are MUCH MUCH easier to get on and seem to fit perfectly. 5'10", 205 pounds and I'm in the size large.

A number of reviews on Amazon and elsewhere have mentioned that these AmFIB Tights run... tight, and advise ordering them a size up. Did that myself because I had always found iZUMi's cycling shorts in Large fit me best (even though at 6', 32"x32", 165 lbs I normally take Medium in pants.) This turned out to be a mistake: the L were too baggy under my butt and around my knees, and way too long (touched the floor.) Returned them for an M which fit much better. New pair reaches down over my ankle bone without excess (are cut to flair out a bit in front to partially cover the instep) . Pleasantly surprised me because the sizing chart only indicates one half inch difference between inseams.

Dunno whether it is because of or despite their being so compressive, but I've found the AmFIBs pretty comfortable while riding my recumbent bike. The lighter, stretchier material sewn in back of the knee allows good range of movement for pedaling, while the minimal fleece interior throughout keeps them from feeling sticky against the skin. This particular tight does not incorporate a chamois, but as "'bents" like mine feature a wide seat rather than the traditional, narrower saddle of diamond frame bicycles, I am happy without the pad. Also this model does not include the stirrups found other of the AmFIBs Elites; again, not a problem. The ankle zippers work great.

Purchased these tights for winter cycling, was a little bit disappointed in that regard: While they did get me sweating as I struggled to pull them on for the first time, the moment I got outside my knees felt cold. Temperature was in the forties, but the wind was terrific, so maybe that had something to do with my poor experience. Still, I had previously gone out riding in flimsy skinny jeans over a Jockey® Stretch Waffle Long John in much colder weather and had felt no chill in my knees whatsoever. Fortunately though, I discovered that if I pre-load these Pearl iZUMis with my Jockeys they will both fit on together without any bunching. Kind of a PITA but the combination of the two is warm enough for riding when the temperature hovers around freezing -haven't had an opportunity to test them in colder conditions than that yet (and don't really wanna.)
