I can't wait to give this a try. I've been looking for a small (<3000 ci) light (< 3 lbs) external frame pack that uses a traditional style frame. The only example I've seen is the DIY one Gardenville made. I was underwhelmed by the Luxurylite Pack which I found outrageously overpriced and carried awkwardly for me. I hope this frame offers up a new option for lightweight, ventable external frame packs.
