Lightweight and poles lock easily
I haven't yet tried these poles at mountain but by my first impression these poles looks great.Well there is no documents but despite so many negative reviews It took me just few seconds to figure out how to adjust the poles length and lock it. What you need to do is to spin both parts of the pole in opposite directions clockwise and counterclockwise to lock and unlock. once unlocked you can raise the poles up and lower to adjust it as one other review here mentioned. Simple and easy.
I will update this review if I find any issues later but so far so good.
