Men's detachable quick drying outdoor shirt Army Green XL(US.Medium)

The purpose for getting this shirt is for my oldest son to wear at Scout meetings, Scout hikes and other Scout events. He has pants that convert into shorts and now a matching long sleeve shirt that converts into a sort sleeve shirt. I think it's a great looking, stylish shirt and my son likes it a lot. He has worn it around the house and has found it to be very comfortable. It's lightweight and perfect for warmer weather. We're getting sub zero in Ohio right now so no hiking yet in it.My son does wear a mens small to medium and this just fits him. So, it does run small. I would say to go one (maybe two) sizes bigger. This isn't the kind of material to shrink from my experience because his Scout pants are made somewhat the same. The stitching seems very durable, I've tugged at the seams and you can't pull them apart like I've seen in cheaper made clothing. I had my son do a lot of stretches and leaps to make sure it didn't tear easily and it didn't. The buttons seems stitched on nicely. The sleeves have a zipper to attach the arms. Worked perfectly. Easy to take on and off. I found no issues at all with that area. The zipper seems of good quality, doesn't pull apart when pulled on.This is a good, versatile shirt that can be worn to both outside events as well as more formal events. We love it and the only reason it got a four star is because runs small. I did get this for free for my honest and unbiased review.
