Z-poles are lighter than folding poles. These are made up of three sections that can be joined by a cord and compacted when they are not in use. These are more costly than telescopic poles, but they are preferred by many ultralight backpackers and fast packers. They are also more fragile. You can buy telescopic poles as one unit or in two or three piece adjustable sets. Two- to three-piece sets are recommended. If you cannot adjust the length of your trekking sticks, they will be heavy and cumbersome.
