Have used the first gen first drop pants, and now i got the black and white vertikas have had them for about 2 months. I have fallen on rails, jumps, rubbed up on trees, and I have zero rips or tears, they changed the materials(i believe) and they seem a lot stronger and can take a beating. The crotch ripping has been solved a lot more room for movement.. I really enjoy the new pants and they are 100% better then the first gens. seams are taped, good water proofing so far I have no complaints!
5'11" 160 got larges and they are a perfect size with the bib attached.
Keep it up First Drop.
