These are great because the bottom is rigid unlike others. They are easy to put in sports vests.

Good Size & Design

Order arrived on time, as advertised, two 500ml collapsible water bottles.After giving them a clean and wash. I like the fact that the screw lid is large making it easy to fill. My bottle didn't smell at all which was also as advertised. The bite nozzle works well, and the bottle after giving it a good shake didn't leak.At the time of this review, £9.99 delivered on Amazon

Great Bottles

I recently acquired a set of these Tentra soft drinks bottles, and I must say, they've quickly become a favourite addition to my outdoor gear. As an avid hiker, I'm always on the lookout for lightweight, practical equipment, and these bottles certainly fit the bill.The first thing that struck me was their incredibly lightweight. Compared to my other water bottles, these are practically weightless, which is a significant advantage when every gram counts on long treks. The soft, flexible material allows them to conform to available space in my backpack, making packing a breeze.Given their soft construction, I was initially concerned about their durability, but they've proven surprisingly robust. The material seems resistant to tears and abrasions, which is reassuring for rough outdoor use.The bite valve is a standout feature for me. It's easy to use and, more importantly, completely leakproof. I can toss the bottle into my bag without worrying about spills. The large opening at the top is great for filling and cleaning, though it does make the bottle a bit bulkier when collapsed.One minor drawback is the lack of insulation, but that's not a deal-breaker for me. The curved bottom, which prevents the bottle from standing upright, took some getting used to. However, the addition of a loop for a lanyard at the bottom is a clever touch, allowing for easy hanging when needed.I've found these bottles particularly useful for air travel. They fold down small enough to fit in a pocket or handbag when empty, making them perfect for passing through security and refilling at water stations.While they may take a bit of getting used to due to their unique design, I've found these hydration bottles to be an excellent investment for my outdoor activities. They're well-made and practical, and solve many of the issues I've had with traditional water bottles. For anyone looking to lighten their load without compromising on hydration, I'd highly recommend giving these a try.

Great walking bottle

These bottles take a little getting used to in that they are very flexible compared to a plastic bottle. Once you are used to them the spout is easy to drink out of, when you finish the bottle they back up pretty small to go into a pocket or can be hung by a lanyard from its bottom to your backpack. They appear to be leakproof. In summer on our walks I think these will be a welcome lightweight accessory
