Best travel packing item - Sea to Summit Ultra-Sil Compression Sack

I was a month in Spain hiking the Camino de Santiago. My friend, who hiked the year before, let me borrow her Sea to Summit compression bags. They are the best thing to use when you need to compress a months worth of stuff into a tight pack, stay organized and help keep things dry when the weather turned wet. (I did use a poncho too on those days) When I returned home my friend got a huge "thank you hug" as I couldn't have made my trek without these. I loved them so much I went and bought my own set. I will use them for my next travel adventures!!
I will even use them when I pack my carry on suitcase.
