The brims make it so that even during a rain storm you can circulate air in the tent. With a shockcorded frame and color coded webbing, the Tetragon 7 should be easy and quick to set up. The bathtub floor, which keeps water out of the tent by raising the floor's seams, works with the StormShield polyester fly to create a dry camping experience. Like its cousin the Eureka Tetragon 5, the Tetragon 7 essentially offers all the features of the Tetragon series on a small scale. In fact, the Tetragon 7 has the exact same features as the Tetragon 5, but in a slightly larger size for a slightly higher price.
