Bought a medium pair for me and large for my hubby just before our hols in the Lake District. Lucky I did! It rained quite steadily much of the time while the rest of the country was dry and warm. The trousers, which could be put on over our walking boots off, kept our bottom halves/trousers dry without making us too warm. If you wear gaiters as well, remember to make sure the waterproof trousers are over the boots under the gaiters, otherwise the water will just drip down into your boots and make your socks wet! The trousers could have been a tad longer too for that purpose as they were only just long enough when gathered by the gaiters specially when bending knees to climb or clamber over styles.
The trousers have reverse pocket slits to prevent them from opening when you bend at the waist while still giving access to your inner pockets- just a little fiddly but ok. For those albeit minor two niggles I gave the trousers 4 stars. Excellent value though.
