Just what the Nalgene needed
Perfect setup for bike mounting Nalgenes, so much easier to utilize, easier to drink from, set it and forget it!

Just what I was looking for
A fellow cyclist did a show and tell if her Swig 63, so I ordered one. Sure is better than my current water system! No plastic taste easy to clean. Added plus that the lid can be taken on and off with a quick release.

So far so good. My concern was it appearing fragile. Also the flat piece for the tubes is separate from the ring. Maybe easier to clean. I had something similar years ago that was sturdier in appearance. I guess time will tell. I very much appreciate that I could use the drink tube I had. Two bottle tubes are included for different sized bottles. I am using mine for two sizes of Thermoflask and it also fits my Polar water bottles. It was harder to find these large mouth adapters. There are many for the typical disposable water bottle.
