This tent will leak like cheese cloth when it rains.
The first time I used this tent in the rain I discovered that the rain fly is like every other rain fly, except that water passes through it like cheese cloth. I was immediately soaking wet. Laid in a soaking wet down bag all night and shivered. MSR says that is because the rain fly was made with defective fabric. The rain proof fabric deteriorates over time. They have known about this for years, but have said nothing. Not even a posting on their own web site. And they told me very clearly that they have no intentions of doing anything that would make this more public. They don't seem to understand the connection between wet and cold all night, and hypothermia. I bought the thing at REI. They have known about the problem for years as well.
