At Rab, our Synthetic and Merino baselayers each have a specific fit.
Our synthetic baselayers are regular fit, designed primarily for spring and summer use in milder conditions. The regular fit enables evaporation by way of a bellowing motion, allowing more air to circulate between the fabric and your skin. On the other hand, our Merino garments are slim fit, trapping air between the fabric and your skin in order to provide insulation, whilst enabling the merino wool to wick and absorb moisture away from your body. Our Merino baselayers are best suited to colder environments, however they still perform excellently in milder conditions due to merino wool’s natural ability to regulate your body’s temperature.
