Light & effective (but not 100%) against mosquitos
I wore this shirt for a five day backpacking trip in Algonquin Park (Ontario). I highly recommend it as it's almost as effective as a bug jacket but less cumbersome. Most of the time you only need to spray your hands and head unless you're really swarmed. It's very light but would be too hot to wear in temperatures above 30 degrees Celsius if exercising strenuously. Although, when I got too hot I undid most of the front buttons for ventilation and oddly neverr got bitten there. It's not completely mosquito proof because when wet the material sticks to your skin and I got a large number of bites on my arms after a rain shower. I wore pants of the same material and while resting watched in amusement as mosquitoes landed on my legs and arms (before the rain) and walked around searching for a way to bite. Some did. Deer flies went for exposed skin and there was very little of that except my hands where i got all of those bites. The two zipped chest packets are useful and the fabric appears durable. One other small feature is that the fabric and cut of the material is very light & loose and traps enough air to help you stay afloat in water. I'll definitely wear this shirt again for summer hiking but also bring a bug jacket for insurance. Possibly I made a mistake in buying a second white coloured shirt and never wore it because I wondered if DEET spray would discolour it. Instead just wore the blue one all the time.
