Great product

I ordered these to try to find a solution to the messy and cumbersome energy gel packs. I don't like the sticky mess they leave in your pockets(especially if you don't consume the whole gel at one time). These were the perfect item. So easy to use on the ride without stopping to tear open packs. No trash to have to carry. Best of all no mess. I loved them so much i ordered more to have for long fondo rides. Fast shipping and a great price too.

A Good Investment

I bought these because I was tired of paying over $1.50 per gel. Basically, I fill the bottle with a 1:3 mix of coffee and maple syrup and it costs almost nothing. That gives me about 300 kcal and 50g of carbohydrates. I usually only carry one flask per ride since I only switch to this higher fuel towards the end of a ride. But the equivalent number of gels to get this nutritional value would be 4-5… close to $10 per ride. I think it well worth the bit of hassle in filling the flask.

Just what I needed

I'm making my own gel/drink and the flasks are just perfect for getting a quick drink of something thinner. And the do well in the top rack of my dishwasher. I like them better than my soft flask.

Love the flask

I used a flask when I did my Ironman personal best of 9h18. It held 75g of carbs and 2g of sodium which helped me stay fueled during the run. I also used when I ran my BQ marathon for a similar reason. I like it and I recommend it.
