For snowshoeing I only had the Ronhill set up or some skiing trousers. Neither seemed the best option: the ski trousers made annoying swishing noises as I walked and they were a bit too warm, the tracksters not warm enough or snowproof at all.
Here is a review (short and very personal) of the trousers I have been trying this winter.
Craghoppers Winter Pika (Short length)
They are also a tiny bit short in the rise, and I have not worn longjohns with them as they felt too tight then.
They are a good length for my legs though. The material they are made from is very nice to wear even though they are not stretchy.
Berghaus Cascade (Short length)
However, they fit me very well, especially round the waist and hips. So with a pair of merino wool longjohns I have been wearing them for cross-country skiing. The knees are very well articulated and length is perfect for me.
Sprayway Warm Challenger (Short length)
