One piece ski suits are back with a bang! 

All-in-one snow suits have made a comeback over the last few years and there’s no denying that seeing a onesie on the slopes always makes you smile. Whether it’s a chicken costume, a vintage high waisted 80s number or an eye-watering vision in neon, they are a LOT of fun. Why should adults be denied babygrows anyway? They’re so damn comfy! Over at Oosc (Original Old School Ski Company) their mission is to bring fun and colour back to the mountains. The creators wanted to bring vibrant, technical and sustainable garments to the masses. And the result? A hugely popular brand with fantastic patterned pieces selling like hotcakes. Ski Club's Sophie took the Scandi Slayer to the Alps to put it through its paces.

There’s no denying that a skier donning a onesie is a sight to behold. Stepping out in my new Scandi Slayer suit I felt snug, secure and ready for anything the pistes could throw at me. But would it be warm enough? The temperature I faced in Alpe d’Huez was -6 but it felt like -25 with wind chill so I really tested the warmth. The advantage with a one piece is that you keep the heat contained inside the suit and reduce the chance of snow or ice finding its way up your back. The suit kept me warm, but not hot, so I would suggest serious layering in mid-winter and advise that the suits are most suited to Easter skiing. 

When I wore the suit off piste, not only did it shine like a beacon to avoid me getting lost down a  crevasse, it prevented snow getting in my waist when we had to search for a lost ski in four feet of powder. With all the heat contained, however, you might find yourself needing to let out some steam. For this, you have ventilation strips running from the armpit to waist. You also have vents on the thighs so you can rest assured that whether you’re smashing the piste or cutting shapes at après, you can thrive at optimum temperature.

The Oosc suits have a spacious breast pocket which is perfect for storing a phone, wallet and suncream or lip balm, with a zip conveniently located in the centre of the chest. It has matching pockets on the upper leg which are not huge, but suitable for storing cash or a card. Like all good ski jackets, the left arm has a small pocket for your pass and the arms are kitted out with wrist gaiters which help the sleeve stay down and prevent snow creeping in. The sleeves are quite narrow at the wrists, so you’ll want to wear gloves that fit over the top because they are unlikely to go under unless they are thin. The collar comes up nice and high to shield your chin from the cold and the hood has handy toggles to tighten it. Although the hood has a slight peak, it might not fit over a helmet.

Need more convincing? Onesie fans will be happy to know that Oosc is friendly to the environment. The company made the decision to overhaul its entire manufacturing process in 2018, to ensure only the finest recycled polyester is used for outerwear and organic cotton for soft goods. Protecting the environment also extends to anyone involved in the process, so production is compliant with the FWF Code of Labour Practices in accordance with the International Labour Organisation. This means that the people making Oosc garments are paid fairly. Technical ski jackets and ski suits are made with 51% recycled polyester from plastic bottles and Oosc creators visit the factories to ensure this process runs smoothly. You can learn more about the full process here. We’ve got a lot of time for these sustainable credentials and any customer will be happy to know their money is helping towards a more sustainable future in snowsports. 

Technical spec aside, the biggest selling point for me is that the Oosc suits are unapologetically lairy and fabulous, whilst keeping you warm at the same time. They are for skiers who don’t take themselves too seriously and want to stand out on the piste and steal all the attention at après. They make you very easy to spot on the slope (I spotted not one but TWO other Scandi Slayers in Alpe d’Huez) and generally break the mould of run-of-the-mill ski outfits. They won’t be everyone’s cup of tea, but for anyone keen to rock the onesie look, it makes sense to invest in one that’s technically equipped for the mountains, instead of freezing in your gran’s vintage suit… no matter how jazzy the racing stripes are.

The Scandi Slayer suit is perfect for a snowsports festival at Christmas time because of the wintry pattern. The design actually separates the outfit out and you can’t tell straight away that it’s a onesie.  I tested it in various conditions across six resorts over the season and it impressed me at every outing, especially when I wore it paragliding above Les Deux Alpes. The suit kept me comfortable and warm during the descent, which took fifteen minutes, and I even matched the ESF instructors and the parachute guide colours so that definitely gets me extra style points. 

Other saucy designs include 80s patterns, rainbows, flamingos and multi-coloured leopard print with cheeky names like Nuts Cracker, Balearic Baller, Fresh Prince and Club Tropicana. You’ll find Oosc online, distributed through retailers like ASOS and at pop up shops in the UK and abroad. Their alpine home is the aptly named L’OOSC Shop at La Folie Douce in Méribel, France, and you might have spotted some Oosc parties both in the UK and abroad. Think disco days, treasure hunts and Folie Douce parties. It’s safe to say onlookers at Rise festival were jealous of my getup, and if it’s good enough for Margot Robbie, it’s good enough for me!
