Gear swap: when to ditch your tent for a tarp
A quick guide to swapping a tent for a tarp when weight, weather, and terrain demand it—no fluff, just the facts.
A tarp can shave 1–2 lb while still keeping you dry in most conditions if you choose wisely.
What happened
After a 300‑mile section of the Pacific Crest Trail, I swapped my 3‑lb tent for a 9‑oz tarp and logged 45 miles in mixed rain without a single soggy night. The change forced me to rethink my shelter strategy and sparked a debate on r/Ultralight.
Why it matters
Weight matters on long thru‑hikes, but shelter failure can end a trip. Knowing when a tarp outperforms a tent lets you stay light without sacrificing safety, especially in variable weather zones.
How to think about it
Start by evaluating your typical climate, campsite options, and skill level. Pick a tarp with a guylines system you can set quickly, practice knot work, and keep a lightweight bivy or groundsheet for cold nights. Test it on a weekend before committing on a long trek.
- Drops 1–2 lb from your pack
- Faster to set and stow
- Improves mobility on steep terrain
- Less wind resistance than a full tent
- Requires more skill to pitch correctly
- Limited privacy
Don’t rely on a tarp alone in high winds or sub‑zero temperatures without a proper back‑wall or bivy.
FAQ
Can I use a tarp in summer heat?
Yes—pair it with a lightweight bug net and a reflective groundsheet to stay cool and bug‑free.
Do I need a separate sleeping bag liner?
A thin liner adds warmth and keeps your sleeping bag clean, but it’s optional if you’re comfortable with a bivy.
What guylines are essential?
At least two tensioned ridgelines and a guy‑line for the windward edge; shock cords make adjustments a breeze.
