Sport loop might be good for your situation. The weave is very breathable and the band is infinitely adjustable. Sometimes with allergic reactions, it can be good to wear the watch looser to give the skin more air. Sport loop makes that easy. I like the Nike version over the regular but both are basically the same.
Braided solo is also nice but isn’t adjustable at all and is expensive. Trail loop is similar to the sport loop but only an option if you have a larger watch or the ultra.
