You probably have something appropriate in your wardrobe already if you’re not wanting to invest in yet more technical wear. A fleece or synthetic mid-layer is best to go over your thermal layer. Best to avoid cotton as if you end up getting it wet it’ll stay damp all day.
Another essential buy! Try and buy some merino or other good quality ski socks which are fitted to the foot, rather than a pair of cheap tube socks. Not only will they last for years, they will ensure your boot fits correctly and your feet stay warm! Don’t be tempted to layer your ski socks you’re your normal socks or double them up – this usually results in colder feet!
A good pair of waterproof ski gloves is essential. Again these will last years if buying a good make. If you are prone to getting very cold hands and are visiting at a colder time of year such as January, consider investing in mittens, or some glove liners for chilly days. There’s literally nothing worse than cold hands!
Worth investing in but can normally be rented in resort, especially for children whose are still growing, helmets are now pretty much essential wear on the slopes for skiers and snowboarders. Make sure you buy one with a good fit and don’t be tempted to buy a larger helmet for a child to grow into; if you’re struggling or you’re buying for a child some helmets come with an adjustable dial at the back. Top tip: try on your helmet with your ski goggles to avoid a ‘forehead gap’ between the two!
