I had a contract position in Sweden and as part of the job I requested a Swedish apartment so I could experience the Swedish lifestyle. It was a small apartment and typical. I was close to buses and trains so I made use of them. There was also a grocery between the train and the apartment so I did not have to keep any food in the apartment except the most basic snacks. Making the grocery my refrigerator and pantry was probably the best lesson and one that I wished at home.And now water bottles.. .
Hikers will buy a smartwater bottle and use it for weeks and months. This bottle became the de facto water bottle as filter and accessory companies modeled their products to that bottle.
About 2 years ago we purchased 4 Nalgene-32 bottles the kids so that they had plenty of water at soccer practice. They complained about the spilling and opening the bottles because the mouth was so wide. So I purchased new lids from HumanGear and things were good. Unfortunately the kids in our league absconded with 2 of the bottles and of course the parents, who should know better, have remained silent.
I purchased a few more Nalgene (pictured above) bottles but in hindsight I regret. I regret it because I cannot seem to convince myself to discard it the way I would a smartwater bottle if I felt I was not going to hike for a while or life was just a little too cluttered.
Keep in mind that water weighs the same regardless of the container. The Nalgene bottles are only slightly heavier. But walking around an airport or just going for a walk I'm likely to feel guilty carrying around the empty Nalgene.
So the lesson... stick with the better water bottles and forget the commercial varieties. Maybe keep a few extra tops in your pack.
