Fortis Ladies Waterproof Legacy Phase I Trousers
They are brilliant trousers for beating and picking-up - as well as for guns on more casual shoots.
These trousers all have a 29" inside leg - which is perfect for most people as these would normally be worn with boots. They have plenty of adjustment room on the waist - there are 2 Velcro adjusters, as well as the main fastener (helpful if you're having a large lunch!) - but as a general guide, the ladies size given is true to size.
