Hammer NutritionGel Flask (Holds 5 Servings)(Return to Product Page)

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.

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.

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.

Good pricing with lightning fast delivery. Will shop here again and again.

HydraPak/GU flask is floppy, leakey and unsanitary-no cap. Hammer solves all those issues and at a much better price.

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!

A good way to carry you energy gel and a lot less messy

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.

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.

Love using this instead of carrying 4, 5, or 6 gel packs. Gel pack tops can be more difficult to open and messy. This one bottle will easily hold 6 (even seven) 1.1 oz gel packs. Top is a bit stiff to open, but repeated use does help to make it easier to open.

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.

... and there are better, like some of the soft flasks available. A good backup to have on hand.

This is a little bigger than I expected. Otherwise, does what it should.

This flask helps me in road races to get fast energy without having to open a gel pack and gel packs hold only one serving and this flask holds 5 and that is awesome.

Great for all hammer products , Gels or Perpentum

I can't ride and open gels so I have to stop to do that. Then I have to catch up as my buddies are hard core and will not wait on me.

So the flask works. I don't need to stop.

And I have no litter to deal with.

That's about it. A solution to my problem.

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

Work great

This product is great for those long training sessions when you need fuel but don't want to carry something big and bulky.
