This is a great shelter if you use Trekking poles. This works for me. The Sil Nylon is a great material and is extremely weather resistant. However, in extremely wet environemnts condensation forms and will drip on you a bit, but it really is nothing when there is a monsoon outside and you are dry inside. It is roomy and light which makes it near perfect. I have sewn bug netting around the bottom and it is well worth the couple of extra ounces. All around it is my favorite backpacking shelter to date and I've had it for more than a year. Oh... Silnet is a must for the seams.
