Thru-Hiker Mesh House 2 Trekking Pole Shelter
Thru-Hiker Mesh House 2 Trekking Pole Shelter
Ultralight weight is critical for thru-hikers and long-distance backpackers, and at .41 kg (14 oz), this shelter meets that requirement and others: excellent ventilation, good protection, and enough livable space for two to be comfortable for weeks or months on the trail. It’s also an extremely packable and adaptable shelter. Use the Mesh House on its own for bug-free protection—a necessity in the High Sierras—or pair it with the Thru-Hiker 70 or 100 Wing (sold separately) for added wind and rain coverage. Whatever the trail—AT, PCT, CDT or TBD—this shelter system lets you configure the right combination of weight and protection that’s right for your trip, and any section along the way.
- Ultralight: Minimum weight of just .41 kg (14 oz) when you use your trekking poles for setup.
- Livable Space: Floor plan accommodates 2 large camping pads plus gear.
- Breathable Protection: Micromesh canopy for maximum ventilation, moisture control and bug-free protection; durable Xtreme Shield™ waterproof floor.
- Added Protection: Pair with a compatible Thru-Hiker 70 Wing or 100 Wing (sold separately) for versatile protection options.

What is California Proposition 65?
Passed into law by California’s voters in 1986, Prop 65 is intended to help California residents make informed decisions about the products they buy.
The law states that companies selling products in California must display a warning when the product contains one or more of the approximately 800 chemicals known to the state of California to cause cancer and/or reproductive harm.
Why has MSR placed a Proposition 65 label on some of its products?
By placing the Prop 65 warning on a product, MSR acknowledges that it contains one or more of the chemicals on the Prop 65 list, however the listed chemical may be well within the “no significant risk” range. MSR has not evaluated every product but out of caution, we include the warning.
Are consumers who use an MSR product with a Proposition 65 label at risk?
The label simply indicates that the product contains the chemical and because of that, there is a potential for exposure to it.
The California government states: “The fact that a product bears a Proposition 65 warning does not mean by itself that the product is unsafe.” The government explains, “You could think of Proposition 65 more as a ‘right to know’ law than a pure product safety law.”
For example, some MSR stoves contain brass. Exposure to brass is not itself harmful. However lead is a component of brass and should the brass be disrupted, a user could potentially come in contact with the lead. While the lead levels fall below the “no significant risk” range, MSR is still required to acknowledge its presence.

What types of chemicals are on the Proposition 65 list?
The Prop 65 list contains a wide range of naturally occurring and synthetic chemicals that are known to California to cause cancer or birth defects or other reproductive harm. They may be additives or ingredients in pesticides, common household products, food, drugs, dyes or solvents. They may be used in manufacturing and construction, or be the byproducts of chemical processes. Proposition 65 requires that the Governor of California maintain and publish a list of these harmful chemicals, and update it annually.
According to the state of California:
A chemical is listed if it has been classified as a reproductive toxicant or carcinogen by an "authoritative" organization on the subject. The U.S. Environmental Protection Agency, U.S. Food and Drug Administration, National Institute for Occupational Safety and Health, the National Toxicology Program, and the International Agency for Research on Cancer are considered authoritative for carcinogens. For reproductive toxicants, appropriate authorities include the U.S. Environmental Protection Agency, U.S. Food and Drug Administration, National Institute for Occupational Safety and Health, and International Agency for Research on Cancer. Chemicals will also be listed if they are required to be labeled or identified as a carcinogen or as a reproductive toxicant by an agency of the state or federal government.
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.
- 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.

At MSR, we voluntarily follow ASTM International F 1934-98 standards around these two tent industry terms. In accordance with this standard, packaged weight includes the total weight of the packaged contents off the shelf. Minimum weight, by comparison, refers to the combined weight of the tent body, rainfly (if applicable) and tent poles, but not any of the other items that may appear in the package, such as tent stakes, guy cords, stuff sack, etc.
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.
Here are a few reasons for those weight variances:
- Coating variances: The thickness in coatings on tent fabric can vary a bit from one tent to another. Fabrics are produced in batches and called “lots,” and there can be a slight weight difference between lots as well as within lots.
- Fabric variances: Because tent fabric is hand cut in up to 200 layers at once, some pieces may be cut just outside the line, making certain parts slightly larger and thus heavier.
- Scale accuracy: At MSR, weights are determined using our calibrated lab scales, which are more accurate than normal household scales.
- Added products: Brands may decide at the last minute to include more stakes or guy cords, which will add to the packaged weight.
If you start to notice leaks along your seams, seam sealing can make them waterproof again, extending the life of your tent. The process can be easier than you might think. We put together this video to help guide you through.
