I have a knollwood/texsport and had it out in heavy rain - after nikwaxing and seam sealing it, it's main problem is the door design is retarded - if you use a small tarp over the door, it's just fine, but the design of the front of the tent is idiotic and no amount
of seam sealing will keep it from leaking.

I still have it, because other than it's inherit design flaw it's really light - I give it
to guests who need a solo tent, and ensure they put a microtarp over the front entrance.
with a little tarp over the dumb front door it works fine even in a deluge. My advice
if you have one, or get one for almost nothing (I paid $15 for mine from someone who
bought it online and didn't like it <img src="/forums/images/graemlins/smile.gif" alt="" /> just find or sew a small silnylon tarp to attach to the
top hoop and go over the door. Then it works just fine.
