While it's impossible to ride year round in some climates, we believe that enjoying as much of the changing colors of fall and the burgeoning foliage of spring from the saddle as possible is one of best reasons for riding, period. With Sugoi's Evolution MidZero Bib Tights, you'll be able to make the most of the transitional seasons and the more temperate days in winter. The Evolution is singularly focused on keeping you warm. To that end, Sugoi makes use of MidZero fabric, which traps warmth and wicks moisture with its soft, brushed lining. You'll stay warm and dry into conditions around 35 degrees Fahrenheit, a temperature at which many of us choose to forsake the road for the indoor trainer. There are some bib tights that will keep you warm at lower temperatures, but they tend to be far pricier than the Evolution and fill a very limited niche in your gear wardrobe. The construction features flat seams that alleviate abrasion and, in a piece of engineering genius, curve around your kneecap instead of riding straight down the center of your leg. This is definitely the part of your body that will suffer most from seam friction in other bibs, but by skirting your knee, the seams of the Evolution skirt that problem. Elastic leg grips keep the seam where it's supposed to be and the seven inch ankle zippers run up the outside of the leg, rather than along your Achilles tendon. The package is rounded off with an RC Pro chamois, Sugoi's go to insert for durability and comfort. The Sugoi Evolution MidZero Bib Tights Men's are available in five sizes ranging from Small to XX Large in the color Black.
