Second to none.

Just five years ago, the Giordana Silverline GIRO Jersey would have been considered gold-caliber kit. As it is, the Silverline's light compression and slim yet unrestrictive fit means it still manages to continually find its way to the front of our jersey queue after laundry day. While its most distinctive feature may be the wool-inspired seams, which encircle the arm and then run straight up the top of the shoulders, it's the jersey's materials that earn it a place on our podium.

The jersey's body is made of MicroPhase, which has a fabric weight of around 135g/m2. That means it lacks the medical-grade compression of a 220 denier compression piece, so it limits the negative effects of road vibration and muscle oscillation with a comfortable fit, not an overbearing one. MicroPhase is also breathable, using a series of fibers that graduate from less absorbent fibers next to the skin to more absorbent fibers at the outside. The outer layer actively pulls moisture while the inner layer actively repels it, keeping your skin dry even in humid conditions.

Giordana doesn't make the mistake of ruining a slim, aerodynamic fit with a floppy collar and baggy shoulders and sleeves. The Silverline borrows the line-topping FRC Jersey's Asteria 2.0 material for these crucial areas. Asteria 2.0 provides a breathable, stretchy fit that continues the jersey's theme of gentle compression to conform to your skin and eliminate any foothold for the wind. But as far as we're concerned, aerodynamic concerns are secondary to fit, and Asteria fits like a dream.

A silicone grip along the back waistband keeps the jersey in place, even while those pockets are loaded with road supplies, and reflective strips on the pockets themselves help keep you visible in low-light conditions.

  • Three standard rear pockets
  • Slim, aerodynamic, lightly compressive fit
  • Fast-wicking fabric

Not for slim build

  • Familiarity: I returned this product before using it

I'm 5'11", 150 pounds, 38" chest. I ordered a medium (37" chest according to specs), but there was still 2 inches of extra material from top of chest to stomach area. Otherwise, fabric looks good and sleeves were comfortable.

Are the sleeves on the longer side? The kind that are common on aero jerseys.
