They are made with 20d silnylon so they are not robust by any means. I didn't make them to rock hop or bush bash with but simply just an addition to my wet weather kit if things are pouring down. My rain coat is quite long so as a rule I rarely even wear rain pants but at 70g and being able to pack down so small I am happy to carry these.

Much to my wifes amusement they ballon out with air when I put them on but once I expel the air they are fine LOL
