    These Storm Pant 2H were recommended to me by Oliver as one of the other products I looked at were no longer available in my size. I normally purchase size M (32 inch waist UK size) however despite being an L they fit very well and no issues regarding leg length. Worn as over trousers and stand alone first impressions are good and they will certainly serve me well across all seasons based upon this April's weather in the UK which has been a right old mixture. However I'm particularly looking forward to seeing how they perform during next Winter as part of a layering system. Delivery was made without any issues arising.

    Great, can't wait for the rain. The knee vents offer exceptional breathability. The drawstring waist is not practical in my opinion.
