The short version
Sleeves for your arms, sunscreen for everything sleeves do not cover. These are not competing. The case for sleeves is that they do not wash off in sweat and do not need reapplying every two hours, which is the failure mode of sunscreen over a twelve hour day. You still need sunscreen on your face, neck, ears and the back of your hands. Wet sleeves also cool by evaporation, which is why people wear them in heat rather than despite it.
Common questions
Does UPF clothing wear out?
The rating drops as fabric stretches, thins and fades, so a sleeve that has gone see-through is not doing what the label promised. Replacing them every couple of seasons of heavy use is sensible.
How much sunscreen do people actually apply?
Consistently less than the amount used in testing, which means real world protection is usually well below the number on the bottle. Applying more, and reapplying, matters more than the SPF you buy.
Is sun exposure a real risk for runners?
Yes. Cumulative ultraviolet exposure is an established risk factor for skin cancer, and endurance athletes accumulate a lot of it. If you have a mole that changes shape, colour or size, get it looked at by a doctor rather than watching it.

Choose the UPF Cooling Arm Sleeves if…
You are out for hours in the sun and you are tired of reapplying. Arm sleeves keep working for the whole day, cost less than a bottle of sunscreen, and can be soaked at every water crossing to cool you down. They also stay put where sunscreen on forearms rubs off against a vest.

Choose the EltaMD UV Sport Sunscreen SPF 50 if…
You need coverage where fabric does not go. Face, ears, neck, the back of the hands and anywhere a vest strap leaves exposed all need sunscreen, and those are the places runners actually get burned. Water and sweat resistant sport formulas last longer, and the reapplication interval on the label is written for people who are not sweating.
