Silicone bands for smartwatches and fitness trackers for watch / bracelet
Rubber/silicone
— a simple, inexpensive and very popular material for making straps for both smartwatches and fitness bracelets. Soft rubber is quite strong and durable, is not afraid of moisture, does not chill your hand in cool weather and does not create discomfort when wearing. Silicone has similar properties, which are practically indistinguishable from rubber in appearance. However, silicone straps are usually softer and more pliable, and also more pleasant to the touch and do not pinch the wrist. Note that rubber itself is a hypoallergenic material. However, some users experience individual intolerance to it, expressed by a rash, redness of the skin and other unpleasant reactions. This is definitely worth considering when choosing a strap for users with sensitive skin.
