I have a thruhiking pack made of a much thinner, less dense version of LiteSkin. All who saw it believed it wouldn't last a weekend, but it's done two Te Araroa tramps (length of NZ) and many other hikes without a blemish nor a leak, and it really is light. That's what drew me to the Top Loader in LiteSkin 42. I haven't had it for long enough to comment on durability, but I am confident about that because of previous experience with the material. Other pros of this product: the size is ideal for my needs (whereas all other TT bags I've owned have been too big or too small) and the cable port - all too rare on TT bags, IMO - is excellent. I run a cache battery in my TT bag that is connected by USB cable to my Cinq Pure stem cap (itself connected to a Son 28 dynamo). From the cache battery, I run a cable back out to my head unit, so I need to pass two cables through the port. The Top Loader can handle that whilst retaining waterproofness. All good! While a zip closure wasn't my ideal choice, the zip on this product is well-positioned and rugged enough for easy and secure access. Very happy so far, and the stichwork and design seems thorough and sensible.
