DRY BAGS: Sea to Summit Ultra-Sil Nano:

Your choice with dry bags can save you quite a few grams. Without them, you could have some sadly wet gear and maybe a disastrous trip. You need to check the seam sealing on the inside of the bags before each trip to ensure they remain waterproof. If you have any doubt, pour a few litres of water into the bag, and see if any can find its way out. If it can, (other than at the opening) I KNOW Sea to Summit WILL replace them. I always use one of their pack liners and have had to swim rivers with my pack a number of times without getting anything inside wet! They have just brought out a new product line (the NANO) which promises 30% weight savings. I have not tried them yet, but I see that the four I currently use (pack liner, 13L, 8L and 1L) would save my 58.5grams! It all adds up. Neither have I tried zpacks’ but all their other products are excellent, and I might save slightly more with theirs (as well as better fitting them in my http://www.zpacks.com/ pack!) Here are some for comparison:
