The Vibrelli 2L Hydration Pack is designed as a practical utility tool for mid-distance activities like cycling or hiking. It features a chassis constructed from 420D Ripstop Nylon, which offers a sturdy build quality capable of handling regular trail use and resisting snags. To find the most comfortable position for your back, the pack includes dual chest and waist straps that help stabilize the load and prevent swaying during movement. The back panel is fitted with a honeycomb mesh to help manage heat and airflow during use.
Specifications indicate that the 2L bladder is made from medical-grade TPU film with a thickness of approximately 0.35mm. This material choice is intended to prevent the "flex-cracking" at seams often found in lower-grade plastics. For those concerned about water flow, the high-flow bite valve utilizes a 90-degree mechanical shut-off switch, which adds a layer of reliability against accidental leaks compared to standard straight-flow designs. However, tests show that storage volume in the secondary pockets can become tight when the water bladder is filled to its 2000ml capacity.
To ensure the best performance from the hydration system, it is important to seat the O-ring perfectly flat before tightening the large-mouth cap, as this prevents gravity-fed seepage. While the pack is built for durability, the plastic hose clip may become more brittle if stored or used in sub-zero conditions, such as during skiing. When starting out with a new unit, an initial rinse is recommended to ensure a taste-free experience.
