It is so important to keep your kids warm and dry when you introduce them to shooting which is why you need this!
I have a age 10 Norsveda full suit in olive drab green. This is a fully lined waterproof, windproof, breathable suit with a Teratex membrane. (It is the same sort of quality as Deerhunter little oscar or seeland kids stuff). It has been worn and has some very minor catches in the material as well as a small rip (less tha 1cm long) in one of the trouser side patch pockets. Other than that, it is a perfect little cosy warm and dry suit with years of life left in it. Yours for only £40 posted!
