This was my first pair - starter set. Trek many miles in all types of terrian work perfect price point unmatched! Choose these over the leki simply because of the easy to use locking system, leki is very hard to use and always slips over the height. I have actually decided to trade up to the top of the line model, I feell these are essential to any hiker or backpacker. Poles are super strong held me 175lbs will all my weight . your back will thank you for investing in these !!!
