Lightweight Camping Guide — Going Ultralight

Every gram you carry on your back affects how far you walk, how much you enjoy the walk, and how tired you are when you arrive at camp. Going lighter doesn't mean going less comfortable — it means being smarter about what you carry.

What Is Ultralight?

The ultralight community generally defines pack weight categories as:

• Traditional: Base weight over 10kg
• Lightweight: Base weight 5-10kg
• Ultralight: Base weight under 5kg
• Super ultralight: Base weight under 3kg

Base weight is everything in your pack except consumables (food, water, fuel). Most people's first wild camping kit falls in the 10-15kg base weight range. Getting below 8kg is achievable for most people without extreme sacrifice.

The Big Three

Your tent, sleeping bag, and sleeping mat together typically account for 50-70% of your base weight. This is where the biggest savings are.

Shelter

For UK conditions, a lightweight one-person tent in the 1-1.5kg range is the sweet spot. It handles wind and rain while keeping weight manageable.

Tarps are lighter but require more skill to pitch effectively, and in heavy rain or strong wind they're less forgiving. They work brilliantly in summer and for experienced campers.

Sleeping Bag

Down is lighter than synthetic for equivalent warmth but costs more and loses insulation when wet. For UK use:

• A quality 600-800 fill power down bag rated to -5°C weighs around 700-900g
• An equivalent synthetic bag weighs 1.2-1.5kg
• A quilt (no back, no hood) saves 200-300g over a traditional bag

If you choose down, use a dry bag to keep it dry. In the UK's wet climate, this is essential.

Sleeping Mat

• Foam mat: Light (200-400g), cheap, indestructible. Not very comfortable. R-value 2-3.
• Inflatable mat: More comfortable, higher R-values, but heavier (300-600g) and can puncture.
• Short mat: Cutting a mat to torso-length saves weight. Put your rucksack under your legs.

Easy Weight Savings

These changes cost nothing or very little:

Leave It Behind

The biggest weight saving is not carrying things. Be ruthless:

• "Just in case" items — if you haven't used it in three trips, leave it
• Too many clothes — one set to walk in, one set to sleep in. That's it.
• Full-size toiletries — decant into small containers or just bring a toothbrush
• Multiple tools — a small knife or multitool is plenty
• Excess packaging — repackage food into zip-lock bags at home
• Books — use your phone (or a kindle, at 180g)
• Camp shoes — your feet will survive one night

Lighter Alternatives

• Titanium pot instead of steel — saves 100-200g
• Gas canister stove instead of multi-fuel — simpler and lighter
• Trail running shoes instead of boots — saves 500g+ per foot (not for everyone or all conditions)
• Stuff sack as a pillow — fill with spare clothes instead of carrying a separate pillow
• Phone as camera, GPS, book, and entertainment — one device, many uses

Multi-Use Items

Every item that serves two purposes saves weight:

• Rain jacket = wind layer
• Sleeping bag stuff sack + clothes = pillow
• Walking poles = tarp poles
• Pot lid = chopping board
• Bandana = towel, pot holder, sun protection

Cooking Weight

Cooking gear can add up fast:

Heavy approach: Multi-fuel stove, separate pans, plates, cutlery, chopping board = 1.5kg+

Lightweight approach: Canister stove, single titanium pot, spork = 300-400g

Ultralight approach: No-cook food (wraps, cheese, salami, nuts, bars) = 0g

Going stove-less is controversial but saves significant weight and bulk. In summer, cold food is perfectly viable for an overnight trip. In cooler months, the morale boost of a hot meal is worth carrying a stove.

Water

Water is heavy — 1 litre = 1kg. Strategies:

• Know your water sources — carry less if you can refill reliably
• Purification tablets weigh almost nothing (lighter than a filter)
• Squeeze filters (like the Sawyer Squeeze) are light and fast
• Don't carry more than you need — 1-2 litres is usually enough if you know where to refill

The Weight Trap

A word of caution: ultralight obsession can become counterproductive.

• Don't sacrifice safety for weight — carry waterproofs, navigation, first aid
• Don't sacrifice sleep quality — a good night's sleep is worth 200g of sleeping mat
• Don't spend thousands replacing perfectly good gear with lighter versions
• Don't become the person who weighs their toothbrush handle

The goal isn't the lightest possible pack — it's the lightest pack that lets you camp comfortably and safely.

A Realistic Lightweight Kit List

Here's a practical lightweight wild camping kit that balances weight and comfort:

• Tent (1-person ultralight): 1.2kg
• Sleeping bag (3-season down): 0.8kg
• Sleeping mat (inflatable, short): 0.4kg
• Rucksack (40-50L lightweight): 0.8kg
• Stove + gas + pot + spork: 0.4kg
• Waterproofs (jacket + trousers): 0.5kg
• Warm layer (puffy jacket): 0.4kg
• Base layers, spare socks: 0.3kg
• Head torch, first aid, map, compass: 0.3kg
• Water (1L) + purification: 1.1kg
• Food (1 dinner, 1 breakfast, snacks): 0.8kg

Total: ~7kg

That's a pack you can walk all day with and barely notice. Compare it with a 14kg traditional pack and the difference in your legs, back, and enjoyment is dramatic.

Getting Started

1. Weigh your current kit — you can't reduce what you don't measure
2. Identify the heaviest items — focus savings where they'll make the biggest difference
3. Leave stuff behind first — free weight savings before spending money
4. Upgrade the big three — this is where money makes the biggest difference
5. Try it — do a short trip with reduced kit and see what you actually miss

Recommended Ultralight Gear

These three items represent the biggest weight savings in the big three categories without breaking the bank.

Lightweight camping isn't about suffering — it's about freedom. A lighter pack means further walks, higher camps, and more enjoyment. Start trimming and you won't look back.
