I've been wearing these trousers for years. Once I find something I like that works I stay with it. Jumping,playing, rolling around, windmilling, smiling, loving - there's space for it all in these trousers. 
Stretch woven Organic cotton Fairtrade trousers made in India to Silverback Tarzan's specs. One size fits all, see pics of trousers on Matt (6ft), Tara (5ft7" ) & Tia (4ft11). Black. Elastic & drawstring waistband.
