Tent is the perfect size for camping with two sons (ages 9 and 7). We have spent several nights in below freezing/high wind conditions. The fly has kept the wind out and we have not had any condensation problems. Love it for the size/weight.
Vestibule is a little small, not much room for anything more than boots.
While I love my Seedhouse SL3, I would consider the Emerald Mountain SL3. See picture for side by side setup.
