It would seem that the sheep in New Zealand must be some of the nicest-smelling in the world. The merino wool that the Icebreaker Mondo Longsleeve Half Zip base layer is made from can be worn repeatedly over several days without any hint of unpleasantness, then machine-washed. It’s a bit thicker and heavier than the synthetic base layers we looked at, so it’s best suited to slightly cooler conditions. Although not particularly long, the neck zip does offer the ability to control your temperature through venting. This in combination with merino’s natural wicking properties means the Icebreaker base layer can still be worn for gentle activities in warmer temperatures. However, it’s in cool, damp weather that you’ll really appreciate the benefits of the Mondo long-sleeve and the fact that merino wool retains its insulating properties even when wet.

Of the base layers we looked at, the Icebreaker Mondo Longsleeve Half Zip is the best for odour resistance.
