User Review: Mountain Hardwear Superlight 72 Chair Pad
Price Paid: $60
A must for the gram counters that still appreciate a few luxuries. I just used it for three days and loved having a chair after a long day. For such a lightweight product it has several nice features like a pocket to stuff clothing for a pillow, a pocket for the poles when rolled, water resistant nylon on the bottom and brathable nylon on the top, and a combo closed/open cell pad for the best of both worlds.
It's a bit large when rolled, but if it's externally mounted...who cares? It's also not quite as comfortable as some plush competitors, but it weighs half as much.
