Rated 5 out of 5 by from Perfect! I bought these Trino tights along with the Trino jacket. I have tried it the tights cycling and running in all kinds of weather and temperature (from 5°C to -10°C, with rain and snow). The tights performs as advertised; they let your sweat in the back and protects the front against the elements. The Trino tighs felt warm while running at -10°C, but way too hot above 0°C. I can't wait to try them at colder temperatures. I am a size 33, 5'8" and I got the medium Trino tights. The waist band is very comfortable and the tights never ride up the crotch. They are fitted, but not too tight. They look a bit like a pair of skinny jeans from a distance. Which is perfect as I do not wish to look like a 15th century nobleman or ballet dancer. The ankles are long and fits perfectly over the top of my running shoes (and stay there). The wind, snow, mud and rain were kept out during my entire runs.

Rated 5 out of 5 by from Best winter running tight The combination premium material, design and cut make this the perfect cold weather training/running tight. Windstopper panels on the front block cold and wet, and mesh panels in the back let heat buildup out. I like that the fit is more relaxed then like traditional tights. I bought extra pairs to also wear around the house in place of sweatpants. A real winner Arc'teryx!

Rated 1 out of 5 by from Updated Arc'teryx Trino Tight's are poor quality! Loved the last year's Trino tight. This years update is terrible. The fit is baggy through the hips, material thin and stiff, and after the first washing the waist band twisted around inside the belt line to make them useless. Shame they changed it. REI was great to take the return. Bought Patagonia's Borderline Tight from REI instead, and they were 2/3 the cost. Happy with them. Very disappointed in Arc'teryx quality on this year's model.
