With the ODLO ACTIVE WARM ECO baselayer top, you can do your bit to protect the environment: only recycled fibres are used in the production of this lightweight, versatile baselayer - the design, innovation and approach are 100% sustainable. Thanks to the ergonomically cut raglan sleeves, the functional underwear also fits comfortably under other layers. Areas of the body that are particularly sensitive to the cold are reliably protected from draughts by the high collar and close-fitting cuffs. With the ACTIVE WARM ECO baselayer top, you'll stay reliably warm and dry on all your adventures in the mountains this winter.
