User Review: Sierra Designs Flash Magic
Ease of Setup: not too bad
Weight: 3 lbs.
Price Paid: $200
Ultralight, but little more than a bivy sack. I've used it at high altitudes in Colorado, and it's great in the snow (got dumped on). On the other hand, it leaks like nuts in the rain, and requires constant seam sealing. I've actually never had it in a heavy rainstorm where it DIDN'T leak. You cannot sit upright in it, and there is barely enough room for one person, much less gear. But for the ounce-conscious, it's not bad.
