The Le Bent Core 200 bottom is their lightest base layer, with a super soft high performance blend of Merino wool and bamboo that loves being on skin and won’t irritate the most irritable of skin types thanks to their Signature Blend. This blend has the added bonus of superior temperature regulation, moisture control and stays odor free far longer than you would think possible. Meaning you can adventure more and wash less. The 200gm lightweight bottoms are created with flat seams to prevent chafing, sculpted panels to provide a performance fit and a wide waistband to distribute pressure and ensure a firm, comfortable hold.
