Sea to Summit did it right!
Bought this for my wife to use backpacking and hut trekking: what a great choice! Right out of the box I could see the thought and care that went into this bag. The accompanying storage,stuff and wash bags are sturdy and well designed. The bag itself has a tough exterior and soft lining. It is roomy and closes down to hold in the heat. The zippers are snag-proof and sturdy...everything in this design seems to be meant for long-term, no-hassle use. Stuffing down the bag, it got to the size of a child's soccer ball: a little bulkier than I thought a bag of this size and rating should be, but not bad. This is a great purchase!
