Ten pounds. That’s the number most ultralight backpackers aim for as their base weight — everything you carry except food, water, and fuel.
It sounds extreme until you do it. Then it feels obvious. A sub-10 lb base weight means you cover more miles with less fatigue, your knees thank you on long descents, and you actually enjoy the hiking part of the trip.
Here’s how to get there without cutting corners on safety.
Start With the Big Three
The “Big Three” are your shelter, sleep system, and pack. These three items typically account for 60-70% of your base weight. Optimize here first — shaving weight on your toothbrush while carrying a 7-lb tent is working backwards.
Shelter: Target Under 2 lbs
A traditional backpacking tent weighs 4-6 lbs. An ultralight alternative weighs 1-2.5 lbs. That’s 2-4 lbs of free weight savings from one swap.
Options:
- Trekking pole shelters — Zpacks Duplex, Tarptent Stratospire: 1-1.7 lbs
- Lightweight freestanding tents — Big Agnes Copper Spur HV UL2, Nemo Hornet: 2-2.5 lbs
- Tarps with bivy for the truly committed — MLD Grace Tarp + Borah Bivy: under 1 lb
Sleep System: Target Under 2 lbs
Down sleeping bags are lighter and more compressible than synthetic for the same warmth rating. A quality 20°F down bag weighs 1.5-2 lbs. Add a Therm-a-Rest Z Lite Sol foam pad (14 oz) or inflatable like the Therm-a-Rest NeoAir XLite NXT (13 oz) and you’re under 2.5 lbs.
The key variables:
- Temperature rating: Don’t over-buy warmth you don’t need — see our guide to choosing a sleeping bag
- Fill power: 850+ fill down = more warmth per ounce
- Quilt vs bag: Ultralight quilts (Enlightened Equipment Revelation, Katabatic Gear Palisade) often weigh 20-30% less than bags
Pack: Target Under 2 lbs
A standard REI hiking pack weighs 4-5 lbs. An ultralight frameless pack weighs 0.5-1.5 lbs.
Frameless packs work when your base weight is under 15 lbs — your gear becomes the frame. Go lighter than that and a Gossamer Gear Gorilla 50 (1 lb 14 oz) or Zpacks Arc Haul Ultra (1 lb 2 oz) will transform how hiking feels. Full review: Zpacks Arc Haul Ultra.
The Rest: Ruthless Editing
Once the Big Three are dialed, go through everything else with one question: do I actually need this, or am I carrying it out of habit or fear?
Kitchen: A titanium pot (3 oz), BRS-3000T stove (1 oz), and mini Bic lighter (0.4 oz) replaces a full cook kit at a fraction of the weight. Jetboil Flash = 13.1 oz. Titanium pot + pocket rocket stove = 7 oz. Same function.
Water: A Sawyer Squeeze (3 oz) weighs less and filters more water than most alternatives. Pair it with a Smartwater 1L bottle and you have a complete water system under 4 oz. Full review: Sawyer Squeeze.
First aid: Build your own kit. Pre-packaged first aid kits are full of things you won’t use. A blister kit, Leukotape P, ibuprofen, wound closure strips, and nitrile gloves weigh almost nothing and cover 90% of backcountry medical needs.
Clothing: The ten essentials of clothing for 3 seasons: base layer, insulating mid-layer, rain shell, sun hat, warm hat, gloves. That’s it. Cotton stays home.
The 10-lb Target in Practice
Here’s a real example base weight breakdown:
| Item | Weight | Link |
|---|---|---|
| Shelter — Big Agnes Copper Spur HV UL2 | 2 lb 6 oz | Buy |
| Sleeping bag — EE Enigma 20°F quilt | 1 lb 2 oz | Buy |
| Sleeping pad — Therm-a-Rest NeoAir XLite NXT | 13 oz | Buy |
| Pack — Gossamer Gear Gorilla 50L | 1 lb 14 oz | Buy |
| Rain shell — Outdoor Research Helium | 6.3 oz | Buy |
| Insulation — Ghost Whisperer 2 | 8 oz | Buy |
| Headlamp — Nitecore NU25 | 1.3 oz | Buy |
| Navigation — phone + offline maps | 0 oz | — |
| Water filter — Sawyer Squeeze | 3 oz | Buy |
| Cook system — BRS stove + Toaks 750ml | 6 oz | Buy |
| First aid kit (DIY) | 3 oz | — |
| Misc — cordage, repair, etc. | 4 oz | — |
| Total Base Weight | ~9 lbs 14 oz |
Under 10 lbs. With gear that handles real conditions.
What You Shouldn’t Compromise On
Going light doesn’t mean being reckless. Some things don’t get cut:
- Navigation: Phone + offline maps (Gaia GPS or CalTopo) + know how to read them. A Garmin inReach Mini 2 adds satellite SOS for remote areas.
- Emergency shelter: A $20 SOL emergency bivy weighs 3 oz and has saved lives
- Rain gear: The mountains don’t care about your base weight goals
- First aid knowledge: The lightest thing you can carry is knowing what to do
The Right Mindset
Going ultralight isn’t about suffering. It’s about being thoughtful. Every item you carry is a choice — make sure each one is intentional.
When you finally shoulder a 12-lb pack for a 4-day trip, you’ll understand. You’ll be moving faster, feeling better, and spending more time actually experiencing the backcountry instead of grinding through it under a mountain of gear.
Pack light. Go far.
