COndensaTIOn
Condensation is an unavoidable fact of physics. When warm, moist air comes
in contact with the cool tent fabric it forms condensation. In most conditions
condensation can be controlled by allowing air inside the tent to vent outside.
During periods of high humidity, such as rain, it can be impossible to remove or
reduce condensation. In these conditions, a high degree of ventilation can actually
increase the condensation by drawing in more humid air.

MSR
®
double-wall tents are designed to allow humid air to pass through the
breathable canopy fabric or No-See-Um mesh and collect on the inner side of the
rainfly. It is normal to find the underside of the rainfly covered in water droplets
in the morning. In humid conditions condensation will also collect on the sill and
parts of the floor inside the tent. This is also normal and does not indicate leaking
floor fabric.

FaBrIC & nO-see-uM Mesh Tears
If your tent fabrics are damaged while on a trip it’s possible to do minor repairs
in the field. The MSR
®
Tent Field Repair Kit (sold separately) includes waterproof,
self-adhesive patches for tent fabrics, No-See-Um mesh, and even clear polyure-
thane for the rainfly. McNett Seam Grip
®
seam sealer is a good option for small
holes. If you have a large tear, Customer Service can also fix your shelter—for
a reasonable fee—after you return from your trip. Normal wear and tear is not
covered under warranty.
POle rePaIr
If a pole breaks, you can make a temporary splint with the pole-repair sleeve
included with your tent. Slide the repair sleeve over the broken section and tape
or wedge it in place to hold it secure to form a temporary repair. After you return
from your trip, contact the MSR
®
Product Service Center for information on a
permanent repair to your pole.
(See detail 4).
FIre
Never use fueled appliances or flame-producing items of any kind inside or near
your tent. Position your shelter away from camp stoves, campfires, or other flame-
producing items.
Minimize condensation by:
• Pitching tent on dry
ground
• Leaving damp items
outside of tent
• Drying tent between uses
• Orienting the tent to take
advantage of breezes
• Venting the inside when
appropriate
