The eye of the storm.
Whether the skies are threatening or it's already pouring, Castelli's Tempesta 3/4 Pants were made to be worn over your tights or shorts to keep your lower half dry no matter what you're riding through — after all, they share their name with a violent, dramatic storm.
Castelli's proprietary eVent microfiber acts as a barrier, blocking rain from getting in but still bringing sweat to the surface of the pants through breathable pores, providing you with a waterproof, seam-sealed shield that won't make you feel like you're wearing a plastic poncho. The knees were specifically shaped to allow for airflow while remaining impermeable to water, which makes the pants breathe so well that — according to Castelli — you can also wear the Tempestas comfortably on dry days to provide you with an additional ten degrees Fahrenheit of warmth.
Castelli understands that the saddle contact area of the pants needs to be comfortable, so its designers constructed the area out of durable three-layer Torrent fabric that stretches more than the rest of the pants, giving you freedom of movement as you're pedaling. When the clouds are dark and brooding, the reflective logo on the left leg helps to make sure you'll be visible to motorists driving with their lights on, and the pants are easy to pull on or off on the side of the road with a simple elastic waist and drawstring closure if the weather changes quickly. When the sun finally comes back out, fold them up and completely pack them away in a jersey pocket or saddle bag.

- Q & A
Why buy a 3/4 pant?
- Familiarity: I've put it through the wringer
- Fit: True to size
- Size Bought: Small
Why? When they're used with the Tempesta leggings.
I've used the combination several times here in Seattle this winter (which is turning into a wet one after last year's dry spell). It poured last Saturday and I wore the Tempesta jacket, 3/4 pants and leggings for over 2 hours. I'd always worn full length Pearl Izumi PRO WXB rain pants prior to buying the 3/4 pants.
The Tempesta 3/4 pants are cut in a relaxed but not loose fit. The silver fabric knees are gusseted but not so much that they flap. The opening at the cuff is also fit close but not snug. In fact, when the knees are articulating through the spin of the cranks, the gussets open and close without much or any restriction. Unlike long pants, the 3/4 pants don't catch on your calves. And the overlap of the 3/4 pants with the Tempesta leggings mean you gained the overall effect of a long pant, with less restriction and better ventilation. You can use a standard non-thermal, non-Nanoflex bib short with this combination.
The eVent fabric of the body of the pants and the reinforcing seat panel have enough stretch to work with you, not against you. Breathability and water resistance seem excellent. Not a bit of water has leaked through, yet. I'll use NikWax Tech Wash and txDirect when it comes time to clean and renew the DWR top coat. Dry for 10 minutes in a dryer on low heat and then hang to finish.
The nicest thing you can say about any piece of kit is that you don't notice or can't tell you're wearing something new or different. The 3/4 pants were, in my opinion, like that. If you buy these pants, try the Tempesta leggings (and vice versa).
