Perfect hiking trousers!
Lovely stretchy material and a high waist, they fit really nicely! Look great and feel really comfy whether sitting down or climbing a hill. They're water resistant, so as a bonus they allow you to sit down for a snack without getting a wet bum!

iris shower resistant skinny fit trousers
I really love the shower resistant feature,all the mud seems to dry and rub off ,so they look good as new at the end of my adventures. However, my slight bug bear is the 28" ones fitted beautifully on my legs,but there was no give on the waist band for my 29" waist ,so were too tight...so I returned them (no hassel from 3rd rock ,brilliant) got myself a 30" waist instead...a bit big on the waist but ok...but to my disappointment the legs are no longer skinny fit ,more of a baggy fit. If the sizes could be a bit more flexible with that material ,that would be great. I need size 28" leg and 30" waist in your product! However, I am keeping the 30" as they do the job .
