The poles I received are significantly better than the ones pictured on the web page. Rather than a black plastic grip and a buckle strap adjustment, these poles have a cork primary grip and a well-designed lower grip of black foam. The strap length is adjusted and held in place by removing, then replacing, a small plastic wedge - this gives a secure strap adjustment with no annoying buckle to deal with. The poles I received extend to about 135 cm, which is sufficient for a tall adult. The description on the web page says 110 cm, which would not be sufficient, at least for most adult males. The adjustments in length are made by using a screw type system, which has, unfortunately, been replaced by many manufacturers with one of the clamp-type systems, which are heavier and can get tangled in brush if traveling off-trail. If you can get the cork-grip model that I received, these are excellent poles for the price.
