AguaForma 2 Collapsible BPA-Free Bottle Set, 18 oz, 2 Count, Best for Outdoor Recreation

I recently purchased these water bottles before taking a trip out to Colorado for a week of outdoor activities and adventures. I was very interested in these bottles for the collapsible aspect to save space while traveling and while they were not being used. I found that these bottles had several characteristics that I believe to be more efficient and superior to any other traditional water bottles. Firstly, the water bottles are very convenient in nature with its collapsible design. Additionally, the bottles are so easy when it comes to TSA and airport traveling since they could fit in my backpack taking up minimal space. Secondly, the bottles are perfect for all outdoor activities and packs. Each bottle comes with a carabiner attached to the ring at the neck of the bottle. While I was hiking, this made it very easy for me to securely attach the bottles to my pack without the fear of them slipping out during the climb. These lightweight bottles are a fraction of the weight compared to my old, hard-shell outdoor bottles with similar durability. I had an absolute blast using these bottles out west and they definitely earned my approval. I continue to use these bottles around the house, going for runs, or at the gym – I truly recommend these to anyone, you will not be disappointed.

Practicing for a 200 mile trek in Scotland so I ordered 4 to try them out. 1 was missing its cap and 1 while on a 20 mile hike started leaking at a folded seam. Not sure the material the bottle is made out of is what I am looking for

Larger than expected but so far so good.

Poor durability. Tore in middle of bottom after only two usages. I would not recommend buying. I did not see a rating suitable for this item.
