The Synaptic 3.0 waist pack is a highly versatile solution, perfect for training runs and races. This updated model features a larger front pocket for increased capacity and a more spacious side zippered pocket, allowing you to carry even more essentials. The enhanced aluminum buckle provides easier entry and closure, ensuring quick access on the go. Designed for functionality, the Synaptic 3.0 allows access to all compartments without the need to remove the belt. It offers ample space for hydration, nutrition, and personal items while remaining lightweight even when fully loaded. Building on the original Synapticβs award-winning stability, the Synaptic 3.0 maintains the same weight distribution ratio and conical belt shape, but with improved features. Equipped with an UltraFlask 550 Hybrid Bottle in its holster, this pack allows for simple and intuitive hydration management. The mesh zippered pocket and additional quick stash pocket on the side provide further convenience, while the front 4-way stretch mesh pocket accommodates a large cell phone without bulk. Shock cord attachments on the front enable you to carry Z-poles or extra layers with ease. One size fits most, making it an excellent choice for all adventure seekers.
