Bottom Line: The Sea To Summit Ultra-Sil Pack Liner keeps your pack completely dry no matter how hard the rain falls on your next backpacking trip.
I bought a large (90L) Ultra-sil pack liner for a multi-week trek in coastal Alaska, where I'd need to haul huge loads of gear & food (76 lbs was my starting weight for this trek) and needed to keep it dry both hiking on land and packrafting across rivers & fjords.
Unfortunately, the bag tore wide open before it ever left my apartment. It was partially my own fault (I picked it up by its top seams while it had about 25 lbs inside), which is why I'm giving it 2 stars instead of 1. But in the end, I wasn't expecting it to be so frail. I used plastic trash-compactor bags for the trek instead, which did the job fine. In the future, I'll just use those and not worry about paying $40 for a pack-liner that doesn't seem to be any more durable.
I'd be happy to try 'em again, if they can make 'em a bit tougher. Maybe I just demand a bit more than some folks, but that's my $.02,
It's a giant dry bag to cover EVERYTHING in your non-waterproof pack. Works perfect, like all S2S products. Not much else to say; if you don't wanna spend like $500 on a completely waterproof pack that squeaks at you with every movement than get a regular pack and buy one of these for the same effect.
Good and durable pack liner. Its good to have extra protection to keep your gear dry. It seems the sizes listed are the amount it can hold once sealed up. But over pretty good fit for most packs.
