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 10/10

How much it adds to your pack. 10: The best you can buy for this.

Montane's UK and EU pages for the regular-fit top give 90 g with no size. 90 g is under 160 g, the 5 band. Ultralight Outdoor Gear lists 90 g for size M (88 g in S). Montane's page for the older trim-fit Dart Nano Long Sleeve also gives 90 g and calls it '30% lighter than the Dart t-shirt'; the regular-fit page makes no such claim. That does not fit the 155 g Dart Long Sleeve, where 30% lighter would be about 108 g, so the 90 g is Montane's figure and we have not weighed it. We band the 90 g it prints; either figure scores 5.

Warmth

Estimate from maker's specs: fibre (no fabric weight published) 3/10

How much the fabric insulates next to your skin. Heavier fabric is warmer and slower to dry. 3: Below average. Fine for some trips, not others.

Estimate from maker's specs

In short

Good for

  • Warm, high-effort days: fast hillwalking, trail running and fastpacking, where weight and drying speed matter most
  • Summer wild camps as a light sleeping top or sun cover, at 90 g
  • A second top to carry for cool starts and evenings when pack space is tight

Strengths

  • 90 g, among the lightest long-sleeve tops we list
  • 100% recycled polyester (APEX Lite) with POLYGIENE odour treatment, per Montane
  • Flatlock seams for a low-profile feel under a rucksack, per Montane
  • Covered by Montane's lifetime guarantee against faults in workmanship and materials

Weaknesses

  • 100% recycled polyester with no merino; odour control comes from the POLYGIENE treatment
  • Montane lists a second Dart Nano Long Sleeve without "Regular Fit" in its name, so check which version a shop lists
