I ordered the fire/after dark color in a size small. The color is a nice red with grey accents on the sleeves and shoulders where there is extra reinforcement of the fabric. My size small weighed in at 37oz on my digital scale, not including the stuff sack. The outer shell is Marmot's Membrain waterproof/breathable material. The fabric seems pretty substantial and capable of taking a fair amount of rough treatment. It also feels like it will be quite water resistant although it remains to be seen how breathable it will be.
