Quick verdict

A short-inseam, four-way-stretch utility pant in the Gamma pattern, sold in waists 30–36 with a tape-measure table and adjustable hem and belt. Independent Gamma reviews cover fit balance, durability and weak venting, but nothing here verifies this listing. Buy off the measurements; between sizes, size up for looser.

Pros

  • · Built-in belt, zippers on all pockets, and an ankle cinch cord for rolling up the legs (reviewer-noted Gamma features).
  • · Slim-but-mobile fit: a 32-inch-waist wearer found it tailored enough to look good while still allowing full mobility.
  • · Durability held: over a month of daily use with no visible wear at seat, knees or ankles, and hard scrapes and thick brush left no visible marks.
  • · Listed spec sheet gives waist, hip, inseam and total length for all four sizes, plus hem and belt adjustment range.

Cons

  • · No back pockets, per Gamma-line reviewers.
  • · Low breathability score (5.0/10) in professional testing of the Gamma.

Fit notes

Listed waists: 30 = 80 cm, 32 = 85, 34 = 90, 36 = 95, with about 5 cm of elastic and belt adjustment. Inseams run 76–79 cm. Arc'teryx's own guidance: between sizes, go up for looser, down for tighter. One owner found their Small Gamma slightly tight, length just right.

Buy if

You want a short-inseam, stretchy pant for commuting, travel and light trail days, and you are willing to buy from the listed waist, hip and inseam numbers rather than a trial run. The 76–79 cm inseams and roughly 5 cm hem and belt adjustment suit shorter or proportionally shorter legs.

Skip if

You run hot on climbs: professional testing scored the Gamma line 5.0/10 on venting and breathability, which cuts against the listing's four-season claim. Also skip if you want a rear pocket, since Gamma-line reviewers report none.

Buying FAQ

Common questions

How should I pick a size?⌄

Use the listing's waist, hip and inseam numbers alongside Arc'teryx's guidance: if your measurements fall between sizes, take the larger for a looser fit or the smaller for a tighter one. Note that Arc'teryx sizing is not the same as standard sizing, and some owners size up because of the built-in belt.

What fabric is this made of?⌄

The listing names two different materials — a high-density climbing cloth and imported TerraTex four-way stretch — so treat the fabric spec as catalog copy and confirm with the seller which one ships.

Does it have back pockets?⌄

Gamma-line reviewers report no back pockets. The listing's features center on two zipped slash pockets, the belt, and the hem cinch, so plan storage accordingly.

Is it really a four-season pant?⌄

The listing claims breathability and year-round wear, but professional testing scored the Gamma 5.0/10 on venting and breathability. It reads as a cool-to-mild-weather pant; warm-weather use is the open question.
