The way Sea to Summit packages these makes them more susceptible to failure.I purchased an 8L and a 20L today. They both have a plastic strip across the top to assist with rolling and closing of the bag. When testing their fitment for an upcoming trip, I was having an issue packing the 8L. In trying to flatten out this plastic piece, it snapped inside, and created a sharp corner that will only wear away the bag from the inside.I then examined the 20L, and I see that the plastic strip inside of that one is already stressed from being folded so that Sea to Summit could save on packaging.

These bags are perfect for keeping gear dry and protected from the elements. I use this size not only for backpacking but I put my phone and similar items in it at the beach to keep them more protected. Maybe not its usual purpose but effective. Not totally waterproof if your gear goes overboard but plenty useful against light rain and spills. Buckle seems light but I haven’t had any problems with it yet. For me, this bag does exactly what it claims.

HEADS UP - this isn't the kindest review courtesy of my lack of sleep. I hope this comes as helpful critique that ensures the future implementation of customer design is the highest quality possible but I'm sure with my current position and short fuse this is going to be a rough read.After 6 nights on this pad I hate this product and cannot stand to take it on the AT or any future adventure. I know y'all put great effort into the engineering but by God this is the worst mat I've ever slept on. I prefer to sleep on the tent floor.The sheer noise it makes was enough to have woken up my fellow campers and the lack of traction on it creates such an uncomfortable balancing act just to stay onboard the mat I felt I was riding a lubed up surfboard on a gliding magic ... MoreHEADS UP - this isn't the kindest review courtesy of my lack of sleep.
