This set of the lightest Ibex base layers ever is ideal for spring-through-fall layering that will come in handy equally on cool summer nights in the alpine, spring skin tracks or fall archery hunts. Comprised of 85% merino wool, Ibex uses a spinning technology that improves the thermal efficiency of its base layers (the warmth-to-weight ratio) by 35%.
At the same time it makes them 85% more elastic and nearly nine times more durable than traditional ring-spun wool layers. That adds up to an impressive innovation that translates directly into more value and higher performance. The top sports a quarter-zip neck, sleeve thumbholes and a raised collar ($170). The bottoms are built with the same ultra-soft, innovative weave and flat, chafe-reducing seams as the top as well as a covered elastic waistband for comfort ($115). Ibex.com
