Our ratings (out of 10)

1 to 10, compared with the whole market. Each says what it's based on. How we score

Weight

From maker's figures 7/10

How much it adds to your pack. 7: Better than most.

Montane's UK, EU and Danish pages give 180 g with no size (its US page gives the same weight converted, about 179 g, in the same band). 180 g is in the 160–199 g band, which is the 4 band. Ultralight Outdoor Gear lists size M at 183 g (S 177 g), a shop figure that also scores 4; we band Montane's 180 g.

Warmth

Estimate from maker's specs: fibre (no fabric weight published) 5/10

How much the fabric insulates next to your skin. Heavier fabric is warmer and slower to dry. 5: Does the job. Average for wild-camping gear.

Estimate from maker's specs

In short

Good for

  • Three-season hillwalking and mountaineering as a next-to-skin top, with the zip to vent heat
  • Multi-day wild camps, where Montane says the merino gives natural odour control between washes
  • Cold, dry mornings and evenings under a fleece or shell

Strengths

  • 180 g (Montane's figure) for a merino top with a zip
  • 84% merino on a nylon core, for strength without giving up merino feel, per Montane
  • YKK Natulon (recycled tape) zip for temperature control, per Montane
  • Trim fit and low-profile merrow stitching for next-to-skin comfort, per Montane
  • Covered by Montane's lifetime guarantee against faults in workmanship and materials

Weaknesses

  • Not pure merino: 84% merino with 11% recycled polyester and 5% elastane
  • The yarn has a nylon core as well as 11% recycled polyester, so it is not all wool
  • Zip length is unclear: Montane calls it a half-zip, while Ultralight Outdoor Gear lists a 1/4 length zip
