Trimmed down and shaped up, the Ultra Light Trail offers the full benefits of patented zone construction and soft alpaca/merino wool, without any of the bulk. Previous versions of the Ultra Light Trail have offered cushion in the foot. However, after some face lifting, this year’s model though truly earns its “ultra light” classification with outstanding fit, moisture control and zero bulk. Content: Absorption Zones: Blend of Alpaca/Merino Wool, Transfer Zone: Alternating rings and channels of Alpaca/Merino Wool and ECO-Dri™, Evaporation Zone: ECO-Dri™ |
