The Icebreaker Mondo Zip weighs 222g (men’s S); closer fit; excellent-quality 100% merino wool won’t smell; very smooth and comfortable; long at rear so unlikely to ride up; various weights available; women’s version is the Chakra. But stitched logo; a longer zip would be better; wool not to everyone’s taste and will soak out in hot weather; surprisingly easy to puncture.

Verdict: The Icebreaker Mondo Zip boasts sublime quality and comfort, but is not the most durable wool base layer.
