Squeeze Bottle

Was perfect size bottle to fit in my jersey pocket and easy to ise

It's a flask for liquids, nothing specific to Hammer products.

It's a plastic flask that's easy to carry. It could be used for any liquid, not just the Hammer products. I do think that it should have marks to indicate volume so it would be easier to measure the "servings" of the liquid/gel.

Better than the other flasks I've tried

Love the hand grip on the side, when you're muscling thru miles 20-26 in a marathon and you need to hold on to something for dear life this fits the bill. The clear cover cap was useless with this for me, you have to be careful when it is upside down as it will leak gel all over your pocket or fuel belt. Easy to fill and clean, no complaints other than perhaps rather than a spout perhaps a one way valve could make the gel delivery a little easier than having to lift the spout with sweaty hands or your teeth.

Great way for cheaper gel

At first I kept buying 12 packs of Hammer gel, then I realized buying a whole bottle and keeping it in this flask is cheaper and I can carry a lot more. Also there is no more carrying used, sticky, gel packets in your jersey, pocket, or fuelbelt pouch. I would give it five stars, but I find it hard to get the last serving out. Rarely when I do deplete the flask, it has been hard to keep up my cadence and get the final serving out.

Fits in your hand, not in your belt

I really like this product, but I wish it came in a smaller size so I could store it in my belt. I can't see any type of belt having a pocket big enough for this bad boy. That being said, it fits comfortably in my hand. And with the body heat from my hand, the gel comes out of the bottle a little smooth (I have only used apple cinnamon - it tastes like pie filling!). The reason I like this so much is that I like to fuel a little at a time...it's perfect for that. I do feel I waste a little bit of gel, I typically either don't finish it all or have trouble getting the last of it out. All in all a great product.
