Slips easily into your jersey pocket, doesn't leak, meters out your dosage and saves money over the individual packs. Good show Hammer!

Better than generic versions of gel flasks. Supple and easy to squeeze with one hand.

I have used these Hammer Nutrition gel flasks for my recent races and they are invaluable for numerous reasons. They are very easy to store in a pocket or down the front of your jersey for easy access. They are well marked for quantity - just keep in mind not all gels are the same volume. The two things I like most about these flasks the finger grips (easy to wrap your hand around - especially if you need to hold onto it while running) and the flow through the spout. Depending on gel viscosity, you can get a full dose of gel out in one squeeze - a major bonus for someone with any concerns about race-day fueling.

In my opinion it they are the absolute fastest way to eat a gel and continue down the roadtrail.

I am a competitive mountain bike racer and using these flasks is the fastest way to take on nutrition in the form of gels and keep moving forward. When I don't need to take a full 5 servings with me (meaning a completely full flask of gel) I always add water to thin out the mix. This not only makes the fueling time even quicker but also ensures you get all the gel out a lot easier. I have a buddy that adds a little brewed coffee to his flasks to add some caffeine.

This flask seems to work best when nearly full-it holds five ounces. The pushpull top forms a secure closure.

It does its job of holding Hammer gel liquid and not creating landfill - I love that part! The clear lid is useless in practicality, not a fault of design, toss it in the trash. The volume it can release on a solid squeeze is low, very low, especially in winter temps. I have learned to suck and squeeze, yea dont tell my friends. Think if a gel pack, how fast you can pull in 2 ounces not possible with this flask. Store it nose down, that will help make the precious sugar evacuate better on demand. I use it on long slow distance days, which has value to me, never on race day or race rides.

This thing is inexpensive, it serves its purpose and is something I never leave behind on long ride days.

I first thought that it was going to be gimmicky, but after a few rides, I don�t know how I got along without it. Yes, it does not work very well if you use 5 gel packs to fill it, but reading online I found the trick is to cut the gels with additional fluid, I use coconut water, at most a 2:3 ratio of coconut water:gel, otherwise its a little too watery for my tastes. The people in my local riding group all asked about it, �wow! thats soo much easier than fighting packs on the road, having to precut things. Not going to miss keeping open/used gel packs in my pockets� etc. Simply put this product is cheap, easily cleaned in the dishwasher (upper rack), has never leaked on me and provides what I need, when I need it. Even if you try it and its not quite to your liking, it is a very small investment and it may just make your rides, that much easier.

I use mine for plain water. I save it for rinsing my eyes. My bike bottles usually have an electrolyte supplement and so I keep this smaller bottle on my jersey. Works great for me.

I use these to carry liquid carbs like molasses and grape juice concentrate to extend my rides past 90 minutes. They are the best flasks I've tried. They are bigger than the 2 other styles I have, squeeze easily, and their tops are easy to open and close and seal securely. I have 2 of them and they are always the ones I pick. Highly recommend.

The size and shape is easy to grab out of a jersey pocket. I like the flat on the bottom for filling. Cleans easily in the top rack of our dishwasher. The bonus for me is the the clear plastic cap works as a dust cap for the camelback podium bottle.

Very very difficult to get the gel out through the nozzle. It is a great idea but the aperture has to be larger.

I'm not a fan of gel packets. The empties are hard to keep track of and I find them difficult to open with teethone hand. I was hoping these little flasks would alleviate the problem and they do partially (no waste) but the gel can be messy (maybe it's just me!) and I end up with it al over my face.

The ergonomics are great, although the top is a little stiff to open. The spout is a large enough diameter for gels to easily flow through. Pretty easy to clean, too. A very good value!

I've dropped Gel packets during rides trying to tear open the packet with my teeth and one hand in order to keep one hand on the bars. This eliminates that risk all the while being able to store more fuel in one location. No more need to jam sticky used packets in your pockets.

No brainer. Get a Hammer Gel Flask and buy your gels in bulk. You will save money and you won't come home with a pocket full of sticky trash. Also, the Gel Flask is easier to open than most single serving gel packs.

I make my own gel when using these. My only reason for giving 4 stars is that the opening is a little small.
