The Regatta Chandler overtrouser is made with Regatt'a own waterproof and breathable Isotex coated soft touch polyester fabric. These overtrousers also have a water repellent polyamide liner to ensure you don't get wet legs (that chaffing could put you out of action for weeks!). The trousers also come with taped seams to ensure complete waterproofness.
Additional features of the Chandler include a combination elasticated and drawcord waist to ensure a snug fit, a zipped gusset at the ankle (for the extremely well endowed), plus adjustable velcro tab at the ankle.
In summary, the Regatta Chandler feature all of the technical features you could want in a good quality overtrouser but with a sensible price tag too!
