I was going to purchase some alpinestars waterproofs to go over my leathers , but after clearing out my wardrobe i found lurking at the back a set of expensive Galvin Green gortex golf 100% waterproofs and after getting into my leathers i then put on the waterproofs to see if they would fit , and hey presto perfect fit , breathable , waterproof , windproof , jobs a good un doubled up usage , what have you combined into double usage
My golf waterproofs have served same. Mind you, the wheel spin wreaks havoc on the greens. Sub 30 min rounds are possible,though!.
