Have owned the GP, the Close Contact & the Dressage models. They are well made, comfortable & the leather is soft & supple. The fit can be adjusted by changing the gullet to make it wider or narrower as the horse changes shape whilst growing or from season to season. The gullet change only takes 5-10 minutes & the only tool needed is a 'Phillps Screwdriver', the gullets cost about £14.95 & range from narrow through several; sizes up to extra wide.
A friend of mine has it and loves it as does her horse - shes not one for loving and looking after her kit either and it doesnt look as worn and battered (though it is structurely sound) as it is.
