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 5/10How much it adds to your pack. 5: Does the job. Average for wild-camping gear.
Arc'teryx's UK page gives 230 g with no size stated, and Snow+Rock lists the same 230 g. CleverHiker's roundup lists a lighter figure of about 159 g for men's M, which would be the 5 band, so the lower-scoring 230 g is banded. 230 g is in the 200–239 g band, which is the 3 band.
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.
Arc'teryx's UK page gives the fabric at 185 g/m². 185 g/m² is in the 150–189 g/m² band, which is the 3 band.
In short
Good for
- Cool three-season hillwalking and wild camps, as a next-to-skin layer
- Mixed-effort days where you start cold and warm up, with a shell or jacket over it
- Camp evenings when a soft, warmer base is wanted
Strengths
- 185 g/m² Torrent jersey knit, brushed inside (warmth score 6), per Arc'teryx
- 230 g (weight score 5), lighter than the zip-neck version
- Crew neck with no zip, so it sits flat under a jacket or rucksack straps
- Laminated chest pocket for a pass or a small map
Weaknesses
- 230 g is mid-range for weight (score 5); lighter base layers exist
- Only one independent test found, so comfort, odour and durability are estimates, not reviewed scores
