Hey. I bought these pants around the start of July 2010. I live in Australia, so I had to go by the measurements on the site. The measurements were not good. I am a size 32" waist and the sizing is totally out (using a small on advice from the dogfunk dude). I needed to send the pants back and missed out using them on my snow trip. I got the medium in the end (on advice from another dogfunk employee). The medium pants are good, but overall, the fit is relatively tight, especially around the rear end region.
In terms of quality, whilst I haven't used them, they are really good. The seems appear strong and the fabric is also strong. I would recommend them, but check on sizing first and only get them if you're looking for a more medium fit pant (no baggy)
