Select Grayl water purifiers $60 - $88 (up to 40% off) for backpacking/travel etc.

I have had the original Grayl filter (the heavier stainless one) since about 2016 and it has been great. Filtered out plenty of lake and stream water on hikes, and used it travelling abroad. Guy in the video review seemed to be trying to force the filter to work faster. It's easier to just press down with both hands on the edges and let the filter go down at a steady pace. Also a fan of it because it doubles as a drinking jug or cup that I don't have to bring, and you don't have to worry about any traditional water pump mechanisms or hoses failing.

Great price on the ultralight 16oz and might have to consider getting another one
