Not DIY, not ripstop, but Leo Köhler make pants (trousers) and shorts from what’s commonly called “German Moleskin”. Different from the UK type as it’s shaved on both sides, and some say not actually moleskin, but very robust regardless. Really comfortable on skin too.
Looks like a great material also! To be honest I will probably just end up going with some breathable nylon, until I can get around to going round a few fabric shops and seeing what’s available, always find it hard looking for fabric on the net never really knowing what to search for.
Us based though, will get stung on customs, was hoping for a stockist in the jk but seems not to be the way!
