u bought from this website ? cheaper ?
I've replaced my ziplock bag with these: http://www.exped.com/international/en/product-category/packsacks/fold-drybag-ul-xxl
For big trips I start with everything in the XXL and slowly move dirty stuff into the XL. At 57g for the XXL (40L), weight is negligible vs the benefits. I switched over when my stash of ziplock bags disintegrated (surface became oily) one day and I had a mild panic attack since I usually start packing 2hrs before having to leave home. Other than being a more permanent solution, the waterproofness has also been a lifesaver and I think it's great to be able to offload unnecessary items at the accoms when I head out overnight or for a few days.
for toiletries, I have a muji toiletries bag and containers. saves a lot of time having everything ready to go all the time and not wasting time trying to buy toiletries overseas.
