Amyhill 3 Pcs Flat Water Bottle 15oz A5 Travel Bottles Leak Proof Slim Square Memo Flask Plastic Portable Travel Mug for Outdoor Sports Fitness Camping Hiking Cycling(Yellow, Gray, Black)

Much more convenient than a cylinder water bottle. I travel a lot and this slides perfectly in my backpack without displacing my books or laptop. Have not had any leaks. Would love to see this with a filter option.

Life happens. It's nasty when it happens in your bottle, unseen, probiotic, like a genie in a bottle.These are great flasks. Travelled with these internationally, relied on them, did not baby them: all good. No leaks, no cracks, no dropped lids. This will fit nicely in your cabin bag/cross-body European Carry-All™ with the rest of your metrosexual accoutrements, or so I'm told.

Bought these to put alcohol in it..for BYOB places

My daughter wanted a square water for her purse and she loves it.

The easy cleaning feature is terrible for keeping the flask sealed, even after using electrical tape to keep the clamps closed any pressure on the bottle, and it leaks past the seal. If you plan on keeping it in a pocket or a bag plan on things getting wet.

Bought these and needed them to be 100% plastic and they were not. Returned them as they didn’t work for the intended purpose.
