Fourth Element Thermocline 2 Women's Leggings
Sea-Changers marine conservation charity
Fourth Element have moved to a universal system (XS, S, M, L etc) from a number system (UK12, US10 etc) to help ensure that you can find your perfect size whether you are shopping online or purchasing from our store.
During the transition period Fourth Element will sell garments labelled with either old or new sizing. This might lead to you receiving an item labelled with a different size to your order. Don’t worry! The measurements match according to the size guide, and you will receive your order with the fit that you want.
Please note: Fourth Element sizes are designed to be snug. For a more comfortable fit, we recommend considering a size up than your usual dress size.
