There is nothing else, literally nothing else I can use without severe drying and skin irritation. Cons:My only gripe with these arms, they have a little bit of slack/play/wiggle against the Hulkfit cage. The top of the case cover always falls off when opening the AirPods case, sometimes even when I don?t open them. Again, not a big deal as they are just on for warmth, but dont expect extreme comfort walking around. Super chulas! The back elastic helps keep them on my daughters feet and are great for playing in the house and yard. Par contre, tissus semble assez fragile. I will continue to buy ?? CON:Now the negatives. So far it hasnt, but it just doesnt feel like its on there securely enough, like it doesnt have anything to grip on to.
