I like the style of the top, and the length of the body and the arms is just about right (at 5'9'' I often find these two measurements to be short), however, the right arm has not been sewn correctly and is slightly twisted. The elastine, after only a few washes (following the instructions) is starting to thread and show itself around the cuffs of the sleaves.
Next time I am looking for a technical top I will look to another brand such as Body Armour, since the quality of the Helly Hanson top is simply not durable, and certainly not to the standard I was expecting from such a well know, long standing brand.
