Great product, easy to clean.

Used in hot temperatures and frequently depend on extra water to carry in the field. Recommend for any outdoor activities.

Great product

I use my Shape-Shift Reservoir every day. I fill it up in the morning and take it with me to work in my hydration backpack. I always have enough water with its 3 Liter capacity. No problems at all after using every day for almost a year.
