Back in the 80s McHale Packs made a pack called the Speed Bump - it was about the size and shape of a large speed bump. That was back in the days of the McHale Light Speed pack as well. McHale Packs actually made 1.5 lb twin stay packs as far back as the 80s but they were designed more as 'Summit Packs' designed to be carried on climbs after long approaches. In the 90s people started UL backpacking with them.
