Down at the beach club or on dress-down Fridays in the office, the Mens Indian Springs Shirt from Jack Wolfskin keeps things relaxed & casual. This long sleeved shirt especially good to wear on really hot days, because the blend of Lyocell & organic cotton has a gentle cooling effect & the fabric has been specially treated to minimise odours. It has a little st&-up collar & the sleeves can be buttoned in place when rolled up, so they don't work their way down.
