Updated Materials

• We're switching more of our tent materials to polyester this year. Why? First off, we're headed towards recyclig tents, and poly recycles while nylon does not. It's also unaffected by temperature swings - nylon tends to say in the cold and tighten in the heat. Ever notice how you're adjusting a tent between morning and afternoon? Ah-ha! Polyester was also once thought to be far weaker than nylon, but newer types offer equivalent strengths over the life of your tent.
