NATIONAL SAFETY APPAREL Unisex Adult Regular Safety Shirts - Light Blue, Large (US Size) | High Visibility Workwear for Construction, Road Crews & Industrial Safety

I love these and have used them for going on 10 years!! I have used Cinch, Ari at, and Wrangler as well over these 10years with Tecgen far exceeding my expectations. These are very thin and breath very well. But the thickness doesn't equate to durability and longevity with these. I am barely replacing ones I have used for 10yrs now. While I have gone through 3+ of the other brands in the same time. My old Tecgen shirts unfortunately are starting to get holes now but are very small and I still wear at work in the oilfields in 100 deg heat everyday. I was pleased with this purchase and I will buy no other brand for as long as I need FR clothing. Highly recommend for those working in hot environments.
