Winter in the mountains transforms everything. Ridges that feel friendly in summer become serious undertakings, gullies fill with snow and ice, and every decision — from what you wear to how you move — matters more. It’s part of what makes winter mountaineering and ice climbing so rewarding: the challenge, the adventure, and the feeling of being completely absorbed in the environment.

But that challenge also demands the right kit. Over the years, I’ve seen how the right equipment can turn a hard, exhausting day into a safe and enjoyable one. So, whether you’re venturing into your first winter season or refining your existing setup, here’s a guide to the essential gear for UK winter mountaineering and ice climbing, along with some practical advice on how to use it effectively.

Clothing: Layering for the Cold

In winter, comfort and safety start with what you wear. You’re constantly balancing warmth, breathability, and weather protection, so layering is key.

Base Layer: A synthetic or merino wool base layer that wicks moisture away from your skin. Avoid cotton — once it’s wet, it stays wet.
Mid Layer: A fleece or synthetic insulated jacket provides warmth without restricting movement.
Outer Layer: A waterproof and windproof shell (Gore-Tex or equivalent) keeps out snow, rain, and spindrift. Look for adjustable helmet compatible hoods and zips for ventilation.
Insulated Belay Jacket: A synthetic (or down in dry conditions) jacket to throw on during breaks or belays.
Legwear: Softshell trousers are great for drier days, while hardshells are essential when conditions are wet or windy.
Gloves: Bring at least two pairs — one for climbing and one for warmth. Wet gloves can end your day early. I often have 4-5 pairs in my bag.
Hat and Buff: Keep your head and neck warm, and carry spares in case they get soaked.

Footwear: Boots, Socks, and Gaiters

A good pair of stiff-soled winter boots is one of the most important investments you can make.

B1, B2, or B3 Boots:
- B1 boots are flexible enough for easier winter walking with strap-on crampons.
- B2 boots are semi-rigid and pair with semi-automatic crampons for general mountaineering.
- B3 boots are fully rigid and ideal for technical ice or mixed climbing.

Look for boots that fit well, provide ankle support, and have insulation for cold conditions.

Socks should be warm and moisture-wicking (avoid layering multiple thin pairs). Gaiters keep snow and ice out of your boots and help protect your trousers from crampon tears.

Technical Equipment

This is where winter mountaineering really diverges from summer climbing — the technical tools and protective gear that let you move safely and efficiently on snow, ice, and frozen rock.

Ice Axe

Your axe is both a walking aid and a life-saving tool.

For general mountaineering, a straight-shafted axe around 55–65cm is ideal for walking, cutting steps, and self-arresting.
For steeper or mixed ground, technical tools with curved shafts and ergonomic handles provide better precision and security.

Learning how to use your axe effectively — for balance, arresting a slip, or building anchors — is an essential skill.

Crampons

Crampons give you grip on ice and hard snow.

10–12-point crampons are standard for mountaineering.
Technical crampons with aggressive front points are suited to ice or mixed climbing.

They attach to your boots via straps, semi-automatic, or automatic bindings depending on your boot type. Make sure they fit snugly — loose crampons are dangerous.

Spend time practicing crampon technique on easy slopes: flat-footing (French technique), front-pointing, and hybrid methods to stay balanced and efficient.

Helmet

A good climbing helmet is essential — not just for falls, but for falling ice or rock. Choose one designed for mountaineering, with good ventilation and a secure fit that works with your hood and hat.

Harness and Ropes

If you’re climbing steeper routes or travelling on glaciated terrain abroad, you’ll need a climbing harness and ropes.

For winter use, look for harnesses that can be adjusted over bulky clothing. Single ropes (9–10mm) are fine for most routes, but half ropes are preferred for longer or more complex climbs, offering flexibility for rope management and reducing drag.

Don’t forget belay devices and carabiners suited for use with gloves — larger, easy-handling designs make life much easier in the cold.

Protection and Anchors

Protection placement changes in winter conditions. You may need to rely on:

Ice screws for ice routes.
Snow anchors (pickets, buried axes, or buckets) for soft snow.
Cams, nuts, and hexes for mixed routes with exposed rock.

Carrying a selection suited to the route and conditions is key. Experience and judgment here come with practice — or with guidance from an instructor or partner who knows the terrain.

Navigation and Safety Equipment

Winter visibility can change quickly, so navigation becomes critical. Always carry:

Map and Compass: Even if you use GPS, know how to navigate traditionally.
Headtorch: With spare batteries — daylight is short in winter.
Avalanche Awareness Gear: If travelling in avalanche-prone terrain, carry a transceiver, probe, and shovel — and know how to use them.
First Aid Kit: Include blister care, tape, and pain relief.
Emergency Shelter or Bothy Bag: Lightweight, and potentially life-saving in bad weather.

The Pack: Carrying It All

A 35–50L pack is ideal for most winter days out. It should be comfortable, weather-resistant, and stripped-back enough to keep things simple. Essentials to carry:

Spare gloves and hat
Insulated jacket
Food and warm drinks
Small repair kit (tape, cable ties, multi-tool)
Headtorch and map
First aid kit
Waterproof layers

Pack heavy items close to your back for stability, and keep frequently used items — gloves, snacks, map — near the top.

Final Thoughts

Winter mountaineering and ice climbing are about preparation and good judgment as much as strength or skill. The right gear won’t make you invincible, but it gives you the margin of safety and comfort you need to enjoy challenging days out in the mountains.

Before investing in kit, it’s worth joining a winter skills course or heading out with an experienced instructor. You’ll learn how to use each piece of equipment correctly and, more importantly, when it’s appropriate to use it.

Once you understand your tools, winter opens up a completely different world of adventure — one that’s cold, wild, and unforgettable.
