What they say: An ultra-fine merino neck tube for effective insulation and natural technical performance in cold conditions. The DHB Merino Neck Tube is warm, comfortable and versatile.
What we say: This product consists of a tube of merino wool (featuring a stitched join) which proved a little scratchy when first put on. The trade-off, though, is a superb warmth and breathability.
Its wicking abilities proved impeccable, too, when worn over the mouth in temperatures that ranged between 3 and TC with zero evidence of moisture accumulating during some pretty lung-bursting efforts.
Not the thickest on test but still provides a surprisingly effective shield against the elements.
