Nalgene 48oz Wide Mouth Silo Bottle

Why We Like It At 48oz, this is the bottle for when a standard cage bottle isn't enough — long dry stretches on the GDMBR, overnight bikepacking loads, or backpacking resupply carries where you actually need the volume without switching to a bladder. It's tall and narrow enough to still fit a downtube cage, which most big-volume bottles can't manage — a lot of oversized bottles solve the capacity problem by getting too wide for anything but a pack pocket. The 2.48" wide mouth means you can drop ice cubes straight in or scoop from a stream source without fighting a narrow neck, and it cleans out easily between trips. We stock it because oversized Nalgenes like this are genuinely hard to find on shelves — most shops stop at 32oz.
