The Motiv Sense fabric used in this shirt contains 81% quick-drying polyester, 11% soft Tencel fiber and 8% elastic elastane. A good choice when short sleeves aren't up to the job - or when you want sun protection. Long sleeves are also comfortable, e.g. against the lining of a shell jacket. Thanks to the flexible material and cut, the freedom of movement is enough for e.g. climbing and disc golf. - Normal Rab fit - not "race tight", still sporty - Flat seams prevent chafing - The hem is slightly longer in the back - Raglan sleeves
