View QC PhotosQuick verdict
A short-inseam Gamma-style softshell pant for buyers whose measured inseam lands near 76–79 cm and who want an adjustable waist and drawcord hem. Public reports on the Gamma line describe a slim, small-running cut, so the listed measurements should decide the size. Compare your own waist and inseam against them before ordering.

Pros
- · Reports on the Gamma line describe a durable, quick-dry stretch nylon softshell with a DWR finish that is said to resist washing better than standard water-repellent coatings.
- · Wearers of Gamma pants describe them as lightweight, comfortable, and stretchy, with good freedom of movement outdoors.
- · Catalog construction: four-way stretch fabric, taped seams, YKK zip hand pockets, three-dimensional knee cut, metal belt buckle, and a stretch waist adjustable across roughly 5 cm.
- · Hem drawcords allow about 5 cm of length adjustment, useful if the listed inseam falls slightly short or long for you.
Cons
- · Public reports on the Gamma line consistently flag a small-running, sometimes tight fit in smaller sizes — a sizing risk if you order by your usual waist number.
- · The listed size 32 inseam is 77 cm, while the official Gamma Pant Short is cited at roughly 79 cm for the same size; the cut here may sit shorter than the model it references.
Fit notes
Listed sizes 30–36: waist 80/85/90/95 cm, hip 100/105/110/115 cm, inseam 76/77/78/79 cm, outseam 101/103/105/107 cm. Waist adjusts about 5 cm; hem drawcords adjust about 5 cm. Gamma-line reports say the cut runs small, so measure rather than assume your usual size.
Buy if
Your measured waist and inseam match the listed chart (30–36, waist 80–95 cm, inseam 76–79 cm) and you want the short cut with a stretch waist, metal belt, and hem drawcords. If you sit between sizes and prefer room, take the larger; for a closer fit, the smaller.
Skip if
You need a standard or long inseam, or you want sizing guidance tied to this exact listing. The available public reports describe the Gamma line generally, and the fit varies by generation — older versions looser, revised ones slimmer — so they may not map onto this pair.

Buying FAQ
Common questions
How does the Gamma cut usually run?⌄
Public Gamma-line reports say it tends to run small — one buyer who normally takes a 34 waist needed a 36 — and that the smaller sizes can feel tight. The listing's own chart is the safer reference.
Is the inseam really short?⌄
The listed inseams run 76–79 cm across sizes 30–36, and the official Gamma Pant Short is cited at about 79 cm for size 32. The hem drawcords allow roughly 5 cm of further adjustment.
Is the fabric water-repellent?⌄
The catalog describes a four-way stretch fabric with a DWR finish, and Gamma-line reports say that coating resists washing longer than standard water-repellent treatments. That is a line-level report, not a test of this pair.
What colors and sizes are listed?⌄
Black, graphite grey, sapphire blue, and misty green, in sizes 30, 32, 34, 36 — corresponding to S through XL.
