My long sleeve shirt arrived for the end of Little Pequaywan, MN's winter and proved to be a light, comfortable under layer for heavy wool, volunteer fireman work or cutting fire wood. It slips on and off easily, washes up nicely. The details of hemming (construction) are well done and comfortable. I'm really looking to summer (ice is not all off the lake, though those loons are back) when I'll be able to have full, but not hot, UVL protection as I sail my Hobbie Bravo. I hope the Spot is noticeable enough to lead to questions. It might be an excellent shirt to wear to "meet the legislators" events also. Bon Voyage for your new product.
