Water Bottle We recommend 2-3 Wide Mouth Nalgene Bottles.\\\\\\\\r\\\\\\\\n\\\\\\\\r\\\\\\\\nHydration Tips 2 to 3 liters of capacity is recommended. Screw top, hard-sided water bottles are preferable, to resist freezing and leakage. Hydration systems can be useful to Camp Muir, however they have a greater tendency to freeze and leak on the upper mountain. While the durability of hydration systems has increased significantly in recent years, we continue to see issues with them when used higher on the mountain as the temperatures are quite cold and the hydration systems rest directly beneath the backpad of the pack, and climbers sit on their packs at rest breaks. As a result, the hydration system tubes (even insulated ones) tend to freeze during the climb or the bladders begin leaking. If you would like to use a hydration system, please still plan on bringing two water bottles as a backup.
