Warmth Sensitivity: While spandex can withstand a range of temperatures, extreme heat may result in deformation or damage, affecting its elasticity.

Some relaxed have on, like jeans, have a little bit versatility due to the fact They're created with a cotton and spandex combination, which can increase consolation and suit.
