I use these tights for riding and running, they work great for both. They are warm and fit great, they kept me dry, but I haven't worn them in a downpour. I'm very happy with them and I wished I would've bought 2 pair while they were on sale.
These are snug enough to require some effort to get on, but plenty stretchy, and once they're on, they keep me completely comfortable into the 30s F on 3- to 4-hour rides. Easily would take me into 20s F if I still did that. Given a choice I prob should have sprung for the suspended tights, since my body's shape (i.e. flat bum) allows them to creep down a bit, though not unreasonably. Not having pads gives me another level of customization whether I use reg tights or knickers underneath for extreme cold, and to vary the chamois. The warmth, breathability and freedom of movement are really amazing. While riding I'm not aware of them at all. Value rating reflects my view that in general cycling kit is grossly overpriced. At least Pearl Izumi gives me peace of mind that whatever I invest in of theirs will last.
These are my deeper winter over-tights when it may get wet. Covers your butt and sheds water, so road spray doesn't give you wet butt.
Extremely warm for such lightweight. Better than thermal bibs, cause you can use these with ALL your regular bib shorts.
Overall they do a good job of keeping my lower extremities warm during 40F - 50F rides. The lack of a zipper at the ankle makes them a little hard to get off at times. I also miss not having a drawstring at the waist to hold them up - I feel like I'm "sagging" at times.
Bought these to replace several well used warm cycling pants. I like not have the ankle zippers and appreciate the snug but flexible fit. Only draw back is no draw string at the waist. Would love to have, but not a deal killer for me. I use at 25F to 40F. Would definitely recommend.
