I bought two of these bottles to replace some leaky polars. Really like the light weight, soft sides, smooth valve function (after I removed the dirt cover) and insulating qualities. My only gripe is that while one of the bottles is great, the other one is slightly oversized and deformed. As a result it doesn't slide into the cage as easily or squeeze as well. Didn't really notice the issue until I had used it and couldn't be bothered to return.
I bought several of these as the paved trail I ride on still has enough grime on it that an uncovered bottle spout attracts more dirt than I want to drink. The insulation is also very effective. If filled with ice water or iced hydration mix, the contents stays cold for about 3 hours even on 90+ degree days and bright sun. The only downside is that the capacity is just a bit over 16 ounces - so I carry 2 on hot days. I've tried other "dirt series" type bottles and they still collect grime on the mouthpiece. These are relatively expensive but work well, especially if you want to drink without swallowing some trail dirt.
I have tried several insulated water bottles and these so far have kept my fluids the coldest for the longest period of time. The lid works really well at keeping dirt of the valve, it does take some time to pop off the cover and get to the valve. Overall, a great product.
I bought this for trail riding and it does keep dirt off the spout, but I wish it held more , it is too small for any long rides.
Keeps water cool for a couple of hours add ice add another hr
This bottle is functional and does keep liquid cold but the lid piece isn't good for the bike. I use this bottle mostly for hiking.
