I previously purchased two Bivo bottles and liked them so much I purchased an insulated one when they went on sale. The bottles are easy to keep clean, are stainless steel and food grade silicone, so no plastic. The flow works as advertised, in fact it can be a little surprising at first when the water gushes out as soon as it's tipped up. I haven't tested the insulating ability yet, since it's still early in the season with few hot days, but I've own similar insulated stainless steel bottles and I see no reason it won't work well.
I've been using Hammer Gel for years. 5 shot flasks (I don't like individual wrapper waste).
Been feeling the legs go as you go farther down the road? Pushed a little too hard on the hills and losing the energy to get back to town? Follow directions on bottle and use regularly.
In trouble and need SAG support? Bottle of H20 and dose accordingly!
NOT your primary source of fuel, a quick and reliable fuel to push through and get up the hill or get back to the barn. See Hammer Gel website for suggested usage.
The previous model had a much better top. Seemed higher quality and easier to use. Not sure why they changed it (cost?). The top of the current model is tight and more difficult to get on and off. Also. the pull top comes off of the new one I have regularly. This is not a deal breaker as you can push it back on easily. I would pay more for a higher quality flask. Possibly food grade silicone? I use this flask on longer rides with Hammer gel in it.
The bottle fits well into a standard cage as long as you have room. I fill it up half with ice and after two hours most of the ice is still there.
During the ride it is fine even if you leave it open but in my bag it leaks even when it is closed which is annoying. Just a few drops every time but still annoying. I might try the CamelBak competitive bottle.
