FS: BD Z Trekking Poles - $70
Great for alpine approaches. Lightweight aluminum trekking poles that collapse into a small package. Easy to store in your pack when not in use. Comfortable grip for your hands and includes the option for a rubber or carbide tip.
I used them twice and they're great, but I'd prefer a shorter length. They have a fixed length of 130 cm.
Retail for $100. I'm asking $70.
