Review (5/5): Perfect for those who only need elbow length cover!
I initially ordered a medium but they were too large and had gaps around the thumb. I sent an email to the seller, Solartex, asking if there was anyway to exchange them for a small. They got back to me right away and put a small in the mail with a postage paid return mailer for the mediums.
The small fit perfectly. I have a very small wrist (about 5.5") so in hindsight, I should have ordered a small from the start. They are just elbow length too which is so hard to find.
I live in Florida and have PMLE (Polymorphic Light Eruption) which means my skin sometimes mistakes UV rays for an attack and I break out in a miserable, bumpy, itchy, burning rash on my forearms. Every other sleeve I found goes to my armpit, but my rash only happens on the back of my hand and forearm. It's so hot here I don't want to wear a skintight sleeve to my armpit! So these are perfect. Provide protection while minimizing how much skin is covered.
In short, these are perfect for people who need forearm sun protection. Seller sent them extremely fast and had extremely helpful customer service. The sleeves are not flimsy and fit well. Highly recommended!
