Keeps me perfectly warm in temperatures down to 27 degrees. Very comfortable for my commute to work (30 miles round trip). On the weekends I really don't ride more than 25-35 miles in one go, and these have been perfectly comfortable for that as well. The fit is consistent with all of my other Castelli tightsshorts (one size up from normal). When BTD has these on sale they're a great value.
I'm 5'11 160 lbs, 32 waist, 33 inseam. I ordered a large...fits perfect. Snug...but light stretchy material. Great chamois. Great for cooler rides in the 55-65 degree F range or under wind pants for winter fat biking.
Great winter tights for Northern California weather. Keep me warm in temperatures down to about 30 degrees, fit exactly like all of my other Castelli gear - size up one from what you normally wear.
These are the most comfortable bib tights I've ever worn. They conform to your body with no chafing and they look good too. I've ridden in 30-40 degree (F) weather and did not feel like they are as warm as advertised. I've also worn them on a climb when I got heated up and they didn't feel clammy. They really breathe well.
