Tell your kids how you rode to work all winter, uphill, both ways.

You can ride all winter, but you have to be prepared for the harshness of the season. Studded tires, thick gloves, and balaclavas are all great things to have, but we're talking about the sport of cycling, where the motors are our legs. If they're icy, you're not moving, and that's why Pearl Izumi made the ultra-warming AmFib Cycling Bib Tight. Designed to fit, wick, and breathe like it's race day, the Amfib has all of the upper echelon luxuries you need on the road, packaged in a warm and weatherproof bib tight.

Pearl Izumi's AmFib Cycling Bib Tight is made from a blend of Pearl's Elite Softshell and Elite Thermal Fleece fabrics. These fabrics were selected in order to ensure a hand-in-hand system of consistent warming insulation, effective moisture transfer, and protection from wind and water. The Thermal Fleece fabric handles thermo-regulation and wicking, whereas the Softshell material has been interspersed in key exposure areas to eliminate element intrusion. The two fabrics coordinate effectively, so much so that Pearl Izumi gives the AmFib tight a thumbs up for weather conditions as low as 15 degrees. In case you're concerned of the tight getting too balmy at the upper end of its 40-degree recommended usage, you can ventilate from an opening at the top of the waist—although its main intention is for easy nature breaks.

Knowing that sub-freezing riding is hard enough, Pearl Izumi wants you to float on the saddle in luxury atop its Elite 3D Chamois. The chamois uses a variable density padding that's been pre-shaped to enhance blood flow. Additionally, its breathable, four-way stretch material creates an abrasion-free surface that conforms to the body as it moves away moisture. And while a comfortable chamois is a necessity, nothing guarantees comfort like a precise fit. To ensure this, Pearl designed the cut to allow full articulation during cycling. The lower leg also follows a contoured shape that leads to an integrated stirrup and a gasket that allows the tight to be worn over a shoe. Not only does this streamline and secure the fit, the design retains an uninterrupted insulation layer. Additionally, the AmFib uses a breathable, but warming, mesh upper and bib straps. Pearl also added 360 degree reflective accents for safer night riding.

The Pearl Izumi AmFib Cycling Bib Tight is available in sizes from Small to XX-Large, and in the color Black/black.

Serious bit of kit

  • Gender: Male
  • Familiarity: I've used it several times

I'm a loyal Castelli customer, but I gotta give PI credit cuz they nailed it with these. Excellent wind and water protection. Heavy and a bit bulky, but what serious winter gear isn't? On the bike, however, they feel awesome and the bottom line is they are WARM. I get cold easily but I've worn them in the 30s and never got chilled. Nice touches include the stirrups (should be standard issue on all tights, imo) and the little access flap for answering nature's call without having to disrobe. I'm 5'11 160lbs 30" waist 38.5" chest and the M fits so perfectly with no bunching. Highly recommend.

Great Winter Tight

  • Familiarity: I've put it through the wringer

I am comfortable wearing this down into the teens. They offer good protection from rain and snow. The chamois is comfortable. The product write up is accurate.

Good Weather Protection, Sizing Off

These bib tights are pretty hefty, with thick softshell on the front protecting legs and the privates. I always wear an XL at least for all cycling clothes including Castelli, Campagnolo, and Zero RH and these were baggy around the thighs and waist in an XL, thus preventing the thermal fabric from warming my skin. I'm returning them for a large.

Great tights

  • Gender: Male
  • Familiarity: I've used it several times

These tights run true to size and like all Pearl Izumi items they are top notch. They are perfect for around 30 degrees. You can wear them in colder temps but expect to be a little cool on the back of your legs where the material is thinner to allow them to breath. Still haven't decided if I should have purchased the ones without the chamois. It would be nice to have another layer underneath in the form of my regular cycling bibs on colder rides. I don't really venture out if its below 20 and these tights have been perfect.
