There are plenty of places in the world where you can survive most of the winter with a long-sleeve base layer and jersey. However, if you try this and choose the wrong base layer, you'll find yourself pedaling back home toward the warm fireplace before you even break a sweat. That's why we recommend the Giordana Heavyweight Carbon Base Layer for winter riding, as it features precise fit, Italian design, and the ability to keep you warm and dry.

To achieve this, Giordana constructed its Heavyweight Carbon Base Layer from Dryarn fabric, a relatively new kind of polypropylene fiber. Basically, it was designed with a winter-weight denier that's been knit into a tubular construction. The tubular composition of the knit creates a varied density over the form of the base layer. You'll find that Giordana designed the fabric to be thicker over your chest, but thinner on your stomach; and thicker on the front of sleeves, while getting thinner around the back. This not only provides comfort while riding, but the next-to-skin fit means that the fabric is more effective in keeping you warm.

Dryarn also provides moisture management in the base layer. As we all know, the warmer that you get, the more that you sweat. But, the question begs to be asked, where does all of the moisture go? If you are out and about in cotton, the answer is 'nowhere.' However, with the second-skin tubular Dryarn knit, moisture is rapidly transported away from the body. In fact, Dryarn's wicking capabilities are so immense that the base layer doesn't need a heavier weight in order to keep you warm. So, the minimal fabric weight promotes a greater ability to breathe, while actually keeping you warmer than most winter-weight fabrics.

  • Heavyweight baselayer keeps you pedaling in frigid winter conditions
  • Synthetic construction is both breathable and moisture-wicking
  • Insulation traps heat even when precipitation puts a damper on things
  • Small presence of spandex in the materials lay-up supplies a formed fit
  • Four-panel design contours to the body under jerseys and jackets

    The size listed as "S/M" actually comes as "M/L", which worked out great for me. It looks tiny when you take it out of the bag but it has a tremendous amount of stretch to it. It fits tight everywhere for that warm, snug feeling. For my weekend ride, I wore just this base layer with a summer jersey and wind vest. Temps ranged from about 48-60 F and I was pretty comfortable the whole time. A little chilly on the arms for a 40+ mph descent at 48-50F, and a I did start getting a little warm at the end of the ride as it was sunny and 60. However, this thing continued to breath well and I never felt too sweaty or clammy. 5 stars for sure. Looking forward to trying it at different temps with varying layers to see how wide a range it can cover.

    Love it!

    I've used it once or twice and have initial impressions

    After 20 years of road cycling I finally caved in and bought my very first base layer. After 2 rides in this, I have to admit that I've made a huge mistake and regret every one of those years that I haven't owned one. So far I've only ridden in temps between 40-65 degrees F, wearing only this base layer and my regular summer jersey on top. The result is immediately noticeable. The first descent out the door at 6am is actually tolerable. I can ride hard all day and I'm still dry. That means I'm not cold even when I stop. I don't quite understand how this works because I'm a sweat hog. I'm a featherweight rider (5'7", 138lbs) and bought an XS. The fit is snug everywhere, but the wrists are a tad looser than I would like. Because of this, they tend to creep up my arms wile riding, leaving a 1" gap to my gloves. This will not be an issue with a long-sleeve jersey or arm warmers on top. It seems like other popular brands (like Craft) tend to stop at size S, so I think Giordana is a prime candidate for petite riders who tend to wear size XS garments. The price is reasonable despite being an Italian premium brand. I do not find the fabric to feel itchy at all, despite wearing it straight out of the packaging. In fact after 150 miles of riding I didn't even notice I had it on at all.

    Very nice product. Fits true to size. Keeps you warm as a base layer when combined with a good wind blocking jacket. Great at 20 d F.

    6'1" 195lbs, size XL fits perfect. got it for about $70 here 5 stars. very warm especially into wind, but not hot when standing. a little more than cheaper brands, but so well-worth it.

    Like surrounding yourself in a skin tight fire, that breaths, and is amazing.... It is a tad itchy at first, but goes away after a few washes.
