Pre-dawn starts, the crunch of snow as you make the first tracks of the day, the sip of a warm drink as steam rises from your Stanley flask, bluebird skies and jaw-dropping silence – nothing beats a winter day out in the hills.
Of course, any trip to the UK’s mountains requires suitable planning and preparation, but when winter comes around things go to a slightly different level. Even as far south as Bannau Brycheiniog (the Brecon Beacons) or on Dartmoor, the weather can be much more extreme in the winter months. You may encounter sub-zero temperatures, ferocious windchill and snowstorms that reduce visibility to zero. Navigation can be trickier to say the least and the risk of hypothermia is real if things go wrong. The terrain can also be much more treacherous, often calling for the use of ice axes, crampons and – crucially – the skills to use them effectively. There are further considerations too. The daylight window is shorter, your backpack will be heavier and in the mountains there can even be other hazards like avalanches to be aware of.
Still, far from putting us off, overcoming these challenges is just another part of what makes winter so rewarding. It all just takes a bit of due care and attention and the right level of preparation…
Here are some absolute essentials to take, particularly when snowy conditions are forecast.
Keeping warm is obviously very important in winter, but bear in mind that the primary aim isn’t necessarily to be as warm as possible. Instead, look to stay at a consistently comfortable temperature where you’re warm enough but also not breaking into a sweat. Sweating can lead to problems when you stop moving or if temperatures drop further, as the moisture on your skin can make you feel much colder, potentially leading to hypothermia, especially if you're not appropriately dressed for the conditions. The best way to maintain a consistently comfortable temperature? The answer there lies in layering.
Let’s start with the first layer: your baselayer. Having a baselayer top and bottoms will go a long, long way to making your day out in the hills an enjoyable one. Look for layers that are close fitting and able to hug the contours of your body without feeling restrictive. Whether you choose a natural fabric or a synthetic one is down to personal preference, though merino wool is generally considered to be the safest bet when dealing with very cold temperatures, because it regulates temperature well and is also able to wick moisture away from the skin.
Mid layers, which should be your main layers of insulation, come in many forms. Fleece jackets are popular for their breathability, warmth, moisture resistance and fast drying times but they can be quite heavy and bulky. Down quilted jackets bring an almost unrivalled warmth-to-weight ratio and are extremely packable but the insulation, unless protected by a hydrophobic water-repellent treatment such as Nikwax, can easily lose its thermal performance in wet weather.
If the forecast predicts wet winter weather, then our recommendation is to choose a jacket with synthetic insulation. Generally, this type of insulating fill isn’t as warm or as light as down but it tends to be more reliable in damp conditions and, in winter, the ability to trust your kit is essential.
Whatever the season and whatever the weather, it’s essential to have a waterproof layer with you. In summer, a lightweight and trim-fitting rain jacket is usually fine but, come winter, you’ll need something that can comfortably accommodate multiple layers underneath. Useful features to look out for include weatherproof zips with internal and/or external storm flaps, ventilation zips and volume adjustment at the hood. Our pick? Patagonia's tried and tested rainwear.
Extremities like hands and feet tend to get colder faster than the rest of the body due to their distance from the core, where the body’s heat is generated. Additionally, blood circulation to these areas can be more restricted in colder conditions as the body prioritises keeping vital organs warm, resulting in less warmth reaching the extremities. As such, protecting your extremities during a hike is vital for temperature regulation, injury prevention, overall comfort and safety.
In winter, always make sure you’ve got a pair of waterproof gloves or mitts – ideally a spare emergency pair too. A common system is to wear a pair of ‘thinnies’ or liner gloves underneath a chunkier pair of insulated waterproof gloves or mitts. Hestra’s Touch Point liner gloves are an excellent example. This means that your hands still have some protection from the cold even if you have to remove an outer glove, say to tie a bootlace, adjust a crampon or buckle a rucksack.
Don’t assume your normal hiking socks will do the job in winter. Instead, invest in a decent pair of technical winter or mountaineering socks like those from Darn Tough or Horizon, ideally with a high proportion of insulating fibres like wool or hollowfibre polyester in the fabric blend. Make sure your socks aren’t too tight as you don’t want to hinder circulation to your extremities (in fact, the same advice applies to your gloves). You might also want longer calf or knee-length socks for winter. These can aid circulation to feet and toes.
An exposed head can actually lead to a drop in your overall core temperature, so headwear is a total necessity in winter. Opt for a hat or beanie that has a wicking material like wool against the skin, complemented by a water-resistant exterior. In harsh conditions, consider layering your headwear by utilising a baselayer-type hat underneath a thicker one. It's also highly beneficial to cover your neck with something like a scarf or neck gaiter (e.g. a Buff).
A simple daypack will often do the job in summer but in winter, with all the above gear, you’ll likely need a backpack with a capacity of at least 30 litres. If you need to carry crampons, look for bags that have outer stash pockets made from durable, spike-resistant materials. Most technical packs are fitted with bungee cords and/or webbing straps that let you secure an ice axe and trekking poles securely.
If there isn’t snow or ice on the ground, a solid pair of waterproof hiking boots will be fine. If there is a risk of snow and icy conditions, you’ll need a pair of boots that are warm, weatherproof and also capable of taking a crampon. To gauge their compatibility, check whether they have a B rating and whether that matches the type of crampon you are using. For instance, B1 boots go with C1 (strap-on) crampons, B2 with C2 (semi-automatic crampons) and B3 with C3 (fully automatic or step-in crampons).
