What is the smallest pack size for foldable trekking poles?

For trail runners, ultralight backpackers, and frequent flyers, pack size is just as important as weight. Foldable trekking poles (Z‑poles) are designed to collapse into tiny bundles that fit inside a running vest, a daypack, or even carry‑on luggage. But how small can they get? Let’s explore the current limits of compact pole design.

The short answer

The smallest pack size for commercially available foldable trekking poles is 33–40 centimetres (13–16 inches). This is the collapsed length of a three‑ or four‑section Z‑fold pole. A few niche models go down to 30 cm, but they are rare, fragile, or custom‑made.

What determines pack size?

Foldable poles use a tension cord (like a tent pole) to hold 3–4 sections together. When collapsed, the sections lie parallel. The minimum collapsed length is determined by the length of the longest single section. To achieve a very short pack size, manufacturers must use more sections (e.g., 4 instead of 3) or make each section shorter. However, more sections mean more joints, which adds weight and reduces stiffness.

Current record holders for smallest pack size

• Black Diamond Distance Carbon Z (36 cm / 14 in) – 3‑section foldable, 300g per pair. The most popular compact pole. Fits in a running vest or small daypack.
• Komperdell Carbon C4 Pro (38 cm / 15 in) – 4‑section foldable, 280g per pair. Slightly longer than Black Diamond but very light.
• Leki Ultratrail FX.One (40 cm / 15.7 in) – 3‑section with a unique folding mechanism that includes a small adjustment range. Slightly bulkier.
• Gossamer Gear LT5 (33 cm / 13 in) – 3‑section, but uses a very short lower section. Extremely compact but also fragile (twist locks). Weight 260g per pair.
• Decathlon Forclaz Carbon MT900 (37 cm / 14.6 in) – 3‑section, budget option at €100.

Is 33 cm the absolute minimum?

For mass‑produced poles, yes. However, some custom or very niche poles go smaller:

• Fizan Compact 3 (aluminum, 32 cm) – rare, twist locks, not very durable.
• Zpacks carbon Z‑poles (custom length, ~30 cm) – made to order for ultralight hikers, but expensive and fragile.

Below 30 cm, the sections become too short to provide sufficient leverage and stiffness. A 30 cm collapsed pole would have each section about 10 cm long – that’s too short for a functional shaft when extended. So 33–40 cm is the practical minimum for a pole that is actually usable.

Why pack size matters

• Trail running: Poles must fit in a running vest or be easily strapped to a belt. Vests typically have pockets 35–40 cm deep.
• Air travel: Carry‑on luggage restrictions are usually 55 x 35 x 25 cm. Poles collapsed to 36 cm fit easily inside a carry‑on (unlike telescopic poles at 60–70 cm).
• Bikepacking: Short poles strap neatly to a frame bag.
• Day hiking: A compact pole can be stuffed inside a small pack when not in use.

Trade‑offs for small pack size

• Stiffness: More sections = more flex. A 4‑section pole is less rigid than a 3‑section pole of the same material.
• Durability: More joints mean more potential failure points. The tiny push‑buttons can jam with grit.
• Weight: More sections require additional hardware (ferrules, buttons, cord), slightly increasing weight.
• Cost: Highly compact poles are often more expensive.

How to choose based on pack size

• Need the absolute smallest (33–36 cm): Gossamer Gear LT5 (fragile) or Black Diamond Distance Carbon Z (best balance). Expect to pay €150–200.
• Good balance of size and durability (37–40 cm): Komperdell C4 Pro or Decathlon Forclaz Carbon. Still very packable.
• Don’t need ultra‑compact (60+ cm): Standard telescopic poles are fine. They strap to the outside of a pack.

Measuring correctly

Collapsed length is measured from the tip (with basket removed) to the top of the grip. Some manufacturers include the tip, some don’t. Always check the specification. For flying, also consider that rubber tips or baskets add a few centimetres – remove them for packing.

Final verdict

The smallest pack size for practical foldable trekking poles is 33–40 cm, with the Black Diamond Distance Carbon Z (36 cm) being the industry gold standard. For most runners and travellers, 36–38 cm is small enough to fit in any vest or carry‑on. Going smaller than 33 cm is possible only with fragile, niche poles that sacrifice durability. Choose based on your primary use: ultra‑compact for running and flying; slightly longer (40 cm) for better durability and lower cost. Always measure your pack or vest pocket before buying – a 36 cm pole won’t fit in a 35 cm pocket.
