How to dress for Up at The O2

Up at The O2 doesn't have a formal dress code, but there are clothing and footwear requirements that are important for your safety and comfort. You'll be wearing a harness throughout the climb, so practical clothing and secure footwear matter far more than style. Skirts, dresses, and unsuitable shoes can make the experience uncomfortable or may need to be replaced with provided alternatives. The most important decision is choosing sturdy, well-fitting shoes and dressing appropriately for the day's weather.

Up at The O2 dress code: Quick facts

  • Dress code: There's no formal dress code, but practical clothing suitable for a rooftop climb is required.
  • Footwear: Wear secure, enclosed shoes with good grip. Your own shoes are fine if they're laced or Velcro with good grip; free climbing shoes and socks are provided if yours don't qualify.
  • Clothing: Wear comfortable, non-restrictive clothing suitable for a full-body safety harness. Trousers, leggings, or shorts are recommended over skirts or dresses. Full-body suits are also available to hire on arrival (fees apply).
  • Weather & layers: The climb takes place outdoors in all weather conditions. Lightweight layers work well year-round, while jackets, gloves, and hats are recommended in winter. Climb jackets and gilets are available as an extra layer.
  • Accessories: Bags, cameras, and GoPros aren't allowed on the climb; phones must stay zipped in a pocket and can only be used on the viewing platform.
  • If your gear isn't suitable: The climb team has final say on the day and will swap you into their own shoes or suit at no extra cost.

Everyday outfit or dedicated climbing gear?

You don't need to buy specialist outdoor clothing for Up at The O2. Comfortable everyday clothes that allow you to move freely are perfectly suitable, provided you pair them with secure, enclosed shoes. If the weather is cool, simply add a light jacket or an extra layer rather than changing into a separate outfit. The best approach is to prioritise comfort, weather-appropriate clothing, and footwear that meets the climb's safety requirements over style.

What to wear for a comfortable climb

You'll spend around 90 minutes outdoors, climbing a steep tensile walkway while wearing a full-body safety harness, so comfort and freedom of movement are key. Choose a breathable T-shirt or lightweight long-sleeved top with trousers, leggings, or shorts that won't restrict movement under the harness. Wear secure, enclosed shoes with good grip, as open-toe footwear and heels aren't permitted. Dress for the weather by adding a light waterproof or warm layer when needed—climb jackets and gilets are available if conditions change. Keep essentials to a minimum, tie back long hair, and store your phone or compact camera securely in a zipped or buttoned pocket before setting off.

Seasonal & weather tips

Summer (June–August)

  • How it feels: Warm days with direct sun on the roof, although breezes can make it feel cooler than at ground level.
  • What to wear: Lightweight, breathable clothing, secure enclosed shoes, sunglasses, and sunscreen. Bring a light layer if the forecast is breezy.
  • Tradeoff: Breathable fabrics keep you cool, but very loose clothing can feel uncomfortable in windy conditions.

Spring & autumn (March–May, September–November)

  • How it feels: Mild but changeable weather, with cooler winds on the roof than at street level.
  • What to wear: Comfortable layers, secure footwear, and a lightweight jacket that you can remove if needed. Climb jackets are also available.
  • Tradeoff: Flexible layers are more practical than wearing one heavy outer layer throughout the climb.

Winter (December–February)

  • How it feels: Cold, windy conditions make the rooftop feel noticeably cooler than central London.
  • What to wear: A warm waterproof jacket, gloves, a hat, and enclosed shoes with good grip. Dress in layers so you stay warm without restricting movement under the harness.
  • Tradeoff: Thick coats provide warmth but can feel bulky beneath the safety harness.

Rainy days

  • How it feels: The climb continues in most wet weather, but the exposed walkway can be slippery and windy.
  • What to wear: Waterproof outerwear, enclosed shoes with good grip, and quick-drying layers. If needed, ask your guide for a climb jacket or gilet.
  • Tradeoff: Waterproof clothing keeps you comfortable, but heavier rain gear can reduce flexibility while climbing.

Is it worth dressing up?

Not really. Up at The O2 is an active outdoor climb, so practical clothing is far more important than a stylish outfit. Comfortable trousers or shorts, a breathable top, and secure enclosed shoes are ideal for the climb. If you're heading to a concert, restaurant, or event at The O2 afterwards, pack a smarter jacket or change of clothes rather than climbing in formal wear. Comfort, safety, and freedom of movement should always come first.
