How should I store my tent?
For long-term storage, keep your tent in a dry and cool area, out of direct sunlight. Store it outside of its stuff sack, as you would a sleeping bag, in a breathable, over-sized cotton or mesh duffel for protection. On the cheap, an old pillowcase is ideal.
How long will a tent last?
What are packaged and minimum weights?
Many MSR backpacking tents can be pitched using only the rainfly, poles and footprint, and in our tent specs we call this non-industry standard setup option our Fast & Light weight.
To learn more about packaged weight vs. minimum, and the manufacturing processes that can affect them, check out our blog post on the topic.

What causes condensation and how do I reduce it in my tent?
- Weather Conditions: High humidity, low temperatures, and rainy conditions create the most condensation.
- People: We produce about 1 - 2 pints of moisture per night through breathing and skin evaporation.
- Wet Environment: Wet ground or wet gear stored inside the tent.
To start, the tent body and ceiling are made of breathable and mesh fabrics. This allows moisture to escape the interior of your tent. However, it must also be able to escape the waterproof fly, and every MSR rainfly has a peak vent that provides protection from the outside, while still allowing essential, free-flowing fresh air to move through your tent. You can also leave a door open in good weather, or take advantage of the double sliders on the doors to vent from the top where warm and moist air tends to accumulate. Make sure to leave at least two vents open if possible, allowing any breeze to provide cross-flow ventilation for maximum circulation. Guying out your rainfly will also increase ventilation in hot or humid conditions.
