Took 2 of these shirts to Kenya & southern Sudan, and they were perfect. In Sudan the temperature was above 100 degrees, and this shirt performed great! Moisture wicked away, no mosquito problem, light weight, UV protection, & plenty of pocket space. In Kenya the Halo Shirt was comfortable in the heat of day and cool of the evening. For the 9 day trip I took 2 Halo shirts, 2 Give-N-Go boxer briefs, and 2 pair of the Insect Shield Convertible pants. They are light weight and take up very little space in a back-pack. At night I washed the briefs and shirts by hand with my body soap and hung them on a hanger. The briefs were totally dry in 1.5-2 hrs and the shirts were dry, smelled fresh, and were ready to wear in the morning. I didn't try hand washing the pants - I'll have to try that sometime to see how fast they dry. The reason the shirt appears to sag in the front (in my picture) is that the pockets are loaded down with food & other stuff:).
