Is the "Dark Heather Grey" light or dark grey? Pictures are mixed.

I ordered it and it was very light colored grey. I try to avoid light grey as it accentuates perspiration. My experience ordering on Amazon is a bit all over the place. Some shirts are double wrapped others seem like they’re counterfeit or inconsistent with packaging. I still need to return the light heather grey I was intentionally trying to avoid.

How many shirts come in this pack?

I also ordered a pack of five and received only one

My teen age son has austim, has senory issues and needs clothes that feel "just right". How soft are these shirts? Thanks!

For the money, they do feel pretty soft. There are certainly softer ones on the market, but for a much higher price

What is the sleeve length like? I generally wear a small but I hate when the sleeves are too short and hike up in the armpits?

Honestly, I bought 1 of each size. I can wear a small. I typically wear a medium due to long arms and wide shoulders. In this shirt to avoid the "Shorter Sleeves", like you mentioned above, I went with a Large. Fit is perfect in the sleeve length and shoulder, but now I have a loose fitting shirt from the below the chest down. After a few washes, it seems to be shrinking just a bit to get rid of the extra. All-in-all, I settled on the medium and bought at least 1 in every color. They are great shirts at this price point.
