Dry for the long haul.
Although it seems counterintuitive, base layers are essential even while riding in warmer months. Their main purpose is to keep moisture off of the skin, which grows in importance on chilly spring/summer mornings. For this reason, Giordana created the Mid-Weight Polypropylene Sleeveless Base Layer. It adds a little more warming protection than Giordana's lightweight base layer, yet it is not so warm that you'll be shedding layers mid-ride.
For the construction of the base layer, polypropylene was selected over the standard polyester for both its moisture management and durability. Polypropylene and polyester are both polymers, meaning that they're both essentially plastics. However, where they differ is that polypropylene is hydrophobic to that point that it's unable to absorb water. And, as a result, it spreads moisture out over a larger surface area, which rapidly accelerates evaporation. So, in short, these fibers ensure that your torso will remain dry over the long haul.
Coupled with the base layer's next-to-skin fit, flatlock seams ensure that you won't chafe while you ride.
The Giordana Mid-Weight Polypropylene Sleeveless Base Layer - Men's is available in the color White and in four sizes from Small to X-Large.

- Q & A
Great for the colder fall/spring temps
- Familiarity: I've used it once or twice and have initial impressions
- Fit: True to size
- Size Bought: Small
- Height: 5'9"
- Weight: 130lbs
I got this for my son to use at his HS MTB race, where temps were around 40 degrees at race-time and it never really got above that. He appreciated having this on under his skinsuit throughout the race, as it helped in keeping his core warm, and some of the colder air out on the descents.
The fabric is smooth against the skin, and even the size small is long enough for his height of 5'9" and would fit upwards of 6'.
