Rab’s Meco is a clever blend of pure ultra- fine merino wool and recycled polyester to give a soft, comfortable & high performance fabric that wicks moisture, dries quickly & resists odours. The 140 refers to the fabric weight of 140g/m². Replace your standard tee shirt with this brilliant shirt & youll be amazed at the difference, it actively pulls moisture away from your skin, controls temperature & resists odours so you feel more comfortable. This 140 weight Tee has a luxurious soft feel & subtle stripes making it perfect for hiking, travel or leisure. 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.
