| Layers | One (waterproof) wall |
| Benefit | Lighter, less bulk |
| Trade-off | More condensation to manage |
| Popular for | Ultralight, mountaineering |
A single-wall tent uses one layer — a waterproof (often waterproof-breathable) fabric — instead of a separate inner and rainfly, to cut weight and bulk. It’s popular for ultralight backpacking and mountaineering, but with no air gap it’s more prone to interior condensation, requiring good ventilation and management.
Weight vs condensation
It saves grams for ultralight backpacking but condenses more than a double-wall tent — vent it well to fight condensation.
Frequently asked questions
What is a single-wall tent?
A single-wall tent has just one layer of waterproof fabric serving as both the body and the weather barrier, with no separate rainfly. This saves weight and packed size, which is why ultralight backpackers and mountaineers use them, but it requires careful ventilation to control condensation.
Single-wall vs double-wall tent?
Single-wall tents are lighter and simpler but condense more inside; double-wall tents add a breathable inner plus a separate fly to manage moisture, at the cost of more weight. Choose single-wall to save grams in dry or cold conditions, double-wall for comfort and versatility.
How do you manage condensation in a single-wall tent?
Maximize ventilation — open vents, doors, and gaps to let moist air escape; pitch away from damp ground and water when possible; avoid cooking inside; and wipe down interior moisture in the morning. Some single-wall fabrics are waterproof-breathable to help, but airflow matters most.
