Review on 💦 Sporteer Soft Hydration Flask - 500 ml - 2-Pack: Stay Hydrated on the Go! by Paul Dobson

These bubble-shaped bottles are ideal for saving space on the go. I was a bit skeptical about this water bottle at first, but I am very happy with this purchase. They're made of soft plastic, so they smell and taste light, but I haven't noticed any harsh or unusual taste when drinking (your taste buds may be different from mine). As you can see from the picture, the bottle does not leak even when squeezed; and will not leak when shaken upside down. When empty, they flatten out, leaving only the top and lid as the bulkiest part (which doesn't take up much space at all). You can also roll up the bottom of the bottle so you can put it in a smaller bag or flatten it for storage in a larger bag without taking up space. If I were to make a manufacturing suggestion, I would ask them to have threads that are comparable to a filter (like the Sawyer Mini); However, this is not a downside of this water bottle, just my personal opinion. Cleaning Tip: Very easy to clean - soap and water, but the orifice is only 7/8 inch inside diameter. To make drying easier, try rolling up a paper towel and tucking it into your empty bladder. Let the top of the paper towel stick I highly recommend washing them before use! As I just received it and have only been using it for a few days I have no comments on durability. I'll update them in a few months I've put them through further testing.
