PLATYPUS QUICKDRAW £35

Water sanitation comes in all shapes and sizes these days, but I love the simplicity and portability of this superlightweight filter. It weighs just 95g and the reservoir just wraps around the filter, taking no space in your rucksack. It works quickly and effortlessly, to decant clean water, free from particles, bacteria and protozoa into whatever container you want (including straight into your mouth). VERDICT Great value bit of kit for back country explorations. USED BY Jenna Maryniak, Trail deputy editor USED FOR 7 months
