Great product, excellent quality, I buy one to try, and I love it. I ride a motorcycle in South Africa, at the end of September, and it’s spring in S A in Sep. the weather can be very cold, or very hot, I travel very light and ride 1,000 miles on few days, I never was cold or to hot, I had the T-shirt and my motorcycle jacket only it was perfect from early in the morning, at noon full sun, and late in the evening. I wear the same t-shirt for 3 days and it was not stinky! Very nice for few days with limited space and luggage.
