Carrying a 50-pound pack turns a hike into a death march. Ultralight backpacking isn’t about suffering with less — it’s about hiking lighter so you can go further, hurt less, and actually enjoy the walk. The concept is simple: every ounce you don’t carry is an ounce your knees don’t have to absorb. Here’s how to make the shift.
What Is Base Weight?
Base weight is everything in your pack minus consumables (food, water, fuel). Traditional backpackers carry 30-40 lb base weights. Ultralight targets are:
- Lightweight: 15-20 lb — achievable with mostly off-the-shelf gear
- Ultralight: 10-15 lb — requires some specialized gear and technique changes
- Super Ultralight: under 10 lb — for experienced minimalists only
Don’t aim for sub-10 on your first try. Getting to 15 pounds is a huge win and makes every trip dramatically more enjoyable.
The Big Three: Where 60% of Weight Lives
Your tent, backpack, and sleeping bag account for the majority of your base weight. This is where upgrades have the biggest impact.
Traditional → Ultralight swaps:
| Item | Traditional | Ultralight | Weight Saved |
|---|---|---|---|
| Tent | MSR Hubba Hubba (3.5 lb) | Zpacks Duplex (1.4 lb) | 2.1 lb |
| Pack | Osprey Atmos 65 (4.5 lb) | ULA Circuit (1.8 lb) | 2.7 lb |
| Bag | Marmot Trestles (3.2 lb) | Nunatak Arc UL (1.5 lb) | 1.7 lb |
That’s 6.5 pounds saved from just three items. Yes, ultralight gear costs more, but your knees don’t care about your budget — they care about your pack weight.
7 Easy Weight Cuts Anyone Can Make
1. Ditch the Nalgene for a Smart Water Bottle
A 32oz Nalgene weighs 6.25 oz empty. A 1L Smart Water bottle weighs 1.4 oz. Same capacity, 5 oz lighter. Multiply that savings across all the “small” items and it adds up fast.
2. Replace Your Pack Towel with a Microfiber Shammy
Regular camp towels: 3-5 oz. Sea to Summit Ultra-Sil Nano towel: 0.7 oz. It dries you just fine and packs to the size of a golf ball.
3. Use a Quilt Instead of a Sleeping Bag
Quills eliminate the bottom insulation (which your sleeping pad compresses anyway) and save 8-12 oz. Enlightened Equipment Revelation (28 oz for 20°F) is the gateway quilt — it takes 2 nights to get used to and then you’ll never go back.
4. Cut Your Toothbrush Handle
I’m not joking. A shortened handle saves 0.3 oz and takes 10 seconds with scissors. This is the ultralight mentality: small savings, everywhere, add up.
5. Repackage Everything
Transfer sunscreen, toothpaste, soap, and bug spray into smaller containers. A full tube of toothpaste weighs 2.5 oz; you need maybe 0.5 oz for a 3-day trip. Ditto everything else.
6. Leave the Camp Shoes at Home
Crocs weigh 10 oz. For short trips, just wear your hiking shoes around camp. For longer trips, use lightweight foam sandals (3 oz). Or go barefoot if the campsite is safe.
7. Replace Your Knife with a Razor Blade
A Leatherman Wave weighs 8.6 oz. A single-edge razor blade in a cardboard sheath weighs 0.1 oz. For 90% of camp tasks (opening packages, cutting cord, trimming moleskin), a razor blade is sufficient.
The Multi-Use Mindset
Every item should serve at least two purposes. Your rain jacket is your wind layer. Your bandana is your towel, pot holder, and water filter pre-filter. Your trekking poles are your tent poles. Your cooking pot is your mug, bowl, and measuring cup. The more hats each item wears, the fewer items you need.
What NOT to Cut
- First aid supplies — reduce quantities, don’t eliminate categories
- Navigation tools — keep a map, compass, or another reliable non-phone backup
- Emergency shelter — even ultralight hikers carry a 2 oz space blanket
- Water filtration — the Sawyer Squeeze weighs 3 oz; giardia is not worth saving 3 oz
- Appropriate clothing — skipping the rain shell to save 6 oz can be fatal
Getting Started
- Weigh everything you currently carry on a kitchen scale
- Sort by weight, heaviest first
- Target the Big Three for upgrades
- Eliminate duplicates and “just in case” items
- Re-weigh your pack — you’ll be shocked at the difference
