I gave the Hydrapak a try today on the ride home. It’s been getting way too hot here and I don’t like being dehydrated by the time I get home.

Pros:

• Large capacity (2.75 liters)
• Insulated. The water in the bag was cold all the way home.

Cons:

• The bite valve is too long to comfortably fit under the chin of the helmet. I need a right angle valve.

All in all a good product. It just needs a little tweaking.
