User Review: Eureka! Tetragon 9
Design: three season freestanding dome
Ease of Setup: easy..two fiber glass shock cord poles
Price Paid: $100
Used this tent for 4 days in Yellowstone (Sept). Tent was roomy, easy to set up. Liked the inside storage pouches and loops for hanging up small LED lights. Had one night of strong rain...no major leaks. Noted that there was a little dripping from roof where tent poles touched the seam. (Would reinforce seams with silcon spray).
Temps at night got down to 35-38 degrees and cold air would flow down from the tarp covered windows. Note that two window panels zip close and the other two are covered via the outside tarp cloth (they do not zip close)so it got chilly inside the tent. This is a 3 season tent provided that all three seasons stay above 40 degrees.
Great tent for "car" camping. Poles are too heavy (IMO) for backpacking.
