I bought these as a last minute purchase for our lightweight camping and gravel bike tour. They are very effective, ultra ultra light weight and there is no worry about spills or split bottles. Will definitely buy them again for our next cycling adventures..
Really neat kit, very compact but when unpacked the sink is big! It can easily be stored on the outside of a pack as it has a loop on the pouch, as well as a drain hole so any water can get out even if you have to pack up without it fully dry.
