Sea to Summit Ultra-Sil 20L Dry Bag - Spicy Orange

I now use this as my main interior sack instead of a pack liner. It's not only useful to stay organized, but it's so much better than using the noisy plastic pack liner, especially when you are packing up and getting out of camp quietly. It's much faster compared to struggling with a plastic pack liner too, as the ultra sil just slips right into my 55L backpack easily. The dry sack does exactly what it does, and I haven't had an issue with moisture leaking inside.

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.

Exceedingly light product. Seems very well built. I tend to be pretty careful with my gear, so I'm reasonably confident these will be tough enough for backcountry backpacking. However, if you anticipate these bags taking any sort of abuse, I would consider going with the Ultra-Sill (not the Ultra-oil Nano). However, time will tell. They're very thin but maybe tougher than they look.
