Rab’s Meco is a clever blend of pure ultra- fine merino wool and recycled polyester to give a comfortable & high performance fabric that wicks amazingly, dries quickly & resists odours. The 120 refers to the fabric weight of 120 g/m² Replace your standard tee shirt with this brilliant piece & youll be amazed at the difference, it wicks moisture, controls temperature & resists odours so you feel more comfortable. Rab Meco fabrics combine 65% ethically sourced Australian merino wool with 35% recycled polyester with Activated Carbon Technology. The Activated Carbon bit is made using natural technology & will not wear off or wash out as it is contained inside the fibres. It is extremely breathable & accelerates evaporation by increasing the surface area by 800%. The activated carbon element absorbs odour molecules which are then released & the technology is refreshed by the warmth from washing & drying. As well as all that it provides a natural UVA & UVB barrier, shielding the skin from harmful UV radiation. The two yarns are intimately blended to produce a high performance fabric that offers all the natural benefits of warmth, softness & odour protection of merino wool, but with the added performance of synthetic & activated carbon technologies. This produces a garment that dries 5 times faster & offers increased odour protection over 100% merino fabrics.
