What Our Gearhead(R) Experts Are Saying:"I wore the Hallie Merino Legging for a week-long trip and it quickly became my go-to. The merino-bamboo fabric is warm yet breathable, and I never felt overheated even while touring. The high-rise fit stays put without squeezing, and I love how they don't hold odor after long days outside."The Hallie Merino Legging keeps us comfortable from early morning skintracks to fireside recovery sessions. Halfdays designed this base layer with a premium blend of merino wool and bamboo fibers, combining warmth and moisture management with an ultra-soft touch. With a high-rise, non-compressive fit, the Hallie sits comfortably under shells or midlayers without riding up or digging in. At 270gsm, the midweight fabric holds in heat during frigid days while still regulating temperature during high-output activity. Naturally odor-resistant and breathable, these leggings are made to be worn back-to-back on multi-day adventures just as easily as they are for lounging after.
