The Hydrobak Light strips a hydration pack down to the essentials without compromising function. At 160 grams empty, it's barely noticeable when you're moving fast, but it holds a 1.5-liter Crux reservoir that delivers fifty ounces of water through a drinking tube positioned right where you need it. If you've been carrying bottles or a larger pack just to stay hydrated on short rides, this is the alternative that doesn't add bulk you don't need.

The Air Support Light back panel uses body-mapped ventilation channels that let air circulate between the pack and your back without creating a sealed contact patch that traps heat. Paired with a ventilated harness that spreads the load across your shoulders, the system keeps the pack stable during movement while preventing the sweaty-back problem that makes you want to ditch the pack halfway through a ride. An adjustable sternum strap pulls the shoulder straps together for better weight distribution and prevents the pack from shifting when you lean into corners or hit rough terrain.

The Crux reservoir uses a Quicklink disconnect system that lets you detach the tube from the bladder without removing the entire reservoir from the pack. This matters when you want to refill mid-ride at a water fountain or when you need to clean the system after use. The tube management system includes a trap that keeps the drinking tube secured along the shoulder strap so it's not flopping around or catching on branches. One liter of cargo space in the main compartment fits a tube, multi-tool, lightweight jacket, or food for rides where you need more than just water. A secure zippered pocket keeps keys, phone, or a wallet separated from the main storage where they won't get wet or scratched.... Read More
