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 8/10How much it adds to your pack. 8: Clearly better than most.
170 g in men's size M (Icebreaker UK) is in the 160–199 g band. Alpinetrek gives 160 g for size M, which is in the same band, and Blacks' page says 255 g (wrong for this top); we use Icebreaker's figure.
Warmth
From maker's figures 6/10How much the fabric insulates next to your skin. Heavier fabric is warmer and slower to dry. 6: A bit better than average.
175 g/m² is in the 150–189 g/m² band. The figure is Icebreaker's own: the 175 in the product name is its fabric weight class, and its base layer guide puts its lightest layers at 75–175 g/m². Alpinetrek lists 175 g/m² too. It is the maker's class, not a lab reading.
What reviewers say (out of 10)
Ratings marked * are from reviews and are not part of the trip score. They are reviewers' scores, not our own measurements. How we score
Comfort*
Estimate: only 1 review about comfort (fewer than the 3 we need, so never above 8) 8/10How soft and comfy it feels next to your skin.
1 review on comfort, e.g. "It's comfortable, soft and fits just right.".
Odour*
Estimate: only 1 review about odour (fewer than the 3 we need, so never above 8) 8/10How fresh it stays after days of wear; higher is fresher.
1 review on odour, e.g. "Great base layer that keeps you warm but has zero odour.".
Drying*
Estimate: only 2 reviews about drying (fewer than the 3 we need, so never above 8) 8/10How well it wicks sweat away and dries.
2 reviews on drying, e.g. "I hang dry it just be safe and dries quickly.".
In short
Good for
- Light three-season hill days and summer wild camps as a base layer or sleeping top
- Wearing as an everyday top in town as well as in the hills: plain rib-knit crew
- Travel and multi-day trips where a merino top beats a synthetic one for smell
Strengths
- 170 g in men's M, light for a long-sleeve top
- Rib-knit fabric with stretch and a slim fit that sits close under a jacket
- Raglan-style construction with offset shoulder seams, per Alpinetrek's listing
Weaknesses
- No independent hands-on test found, so comfort, odour and durability are estimates, not reviewed scores
- Light 175 g/m² fabric: not warm enough alone for a cold night
- Pure merino with no nylon: expect it to thin sooner than a nylon-core blend with hard use
- Shop weights disagree (Icebreaker 170 g, Alpinetrek 160 g, Blacks 255 g): we use Icebreaker's
- Do not tumble dry
