Best Use: All Conditions
Developed in New Zealand, Nuyarn technology has revolutionized the Merino wool market. Taking the twist out of the yarn has produced a fabric with higher stretch and recovery, better moisture management, and greater warmth. It is stronger than the average Merino wool on the market, yet boasts the same natural odor resistance and comfort.
KUIU's ULTRA Merino 145 is a lightweight, incredibly comfortable, and durable blend of wool and nylon providing a next to skin or layering option for the highly active hunter. Itch-free, moisture wicking, and naturally odor resistant, the ultra fine 17.5 micron Merino wool takes the edge off in cool conditions, while the full length leg zippers and above the boot design allow you to easily add or shed layers in changing weather conditions without removing your boots and outer layer pant.
This base-layer bottom is sized with an athletic next-to-skin fit to layer over a brief and under a hunting pant. Only upsize if you measure between sizes.
Layering Example – Cold Conditions: *For an individual measuring size: L / 36R
Brief: ULTRA Merino Boxer Brief – L
Base Layer: ULTRA Merino 145 Zip-Off Bottom – L Hunting Pant: Attack Pant – 36R
