Hydration leader expands Seeker platform with a dual-bag gravity system designed for efficient group and basecamp water filtration

Oakland, CA /OUTDOOR SPORTSWIRE/ – HydraPak is launching the Seeker+ 6L Gravity Kit, a high-capacity gravity water filtration and storage system designed for backpacking, camping, and extended backcountry travel. Designed for groups and basecamp use, the Seeker+ 6L Gravity Kit delivers fast, pump-free filtration in the backcountry.

The Seeker+ 6L Gravity Kit is a dual-bag water filtration and storage system built around HydraPak’s proven Seeker platform. The wide-mouth “dirty” bag fills easily from shallow or slow-moving sources, while the flat-weld “clean” bag minimizes trapped air to prevent vapor lock. Integrated lash points on both bags allow the system to hang freely and let gravity do its job with no pumping required.

At the core of this group water filtration system is a 63mm Plug-N-Play filter cap (an easy-to-use, twist-connect interface) that removes E. coli, Cryptosporidium parvum, and Giardia lamblia from up to 1,500 liters at 1+ liters per minute. An integrated pre-filter blocks debris to extend filter life, and the Camp Tap allows simultaneous filtering and dispensing with controlled pouring for cooking and camp use. The filter is backflushable to restore flow rate over time, and both bags pack into the included stuff sack for compact storage.

“The Seeker+ 6L Gravity Kit is an upgrade to the classic high-volume gravity water filters that are currently on the market” said Jon Austen, Vice President of Product at HydraPak. “By building upon our successful Seeker+ line, this kit includes our all-new pre-filter technology which protects the main filter from large debris and helps prevent clogs.”

Key Specs:

• Capacity: 6 liters (dual-bag system)
• Flow rate: 1+ liter per minute
• Filter lifespan: ~1,500 liters
• Removes: E. coli, Cryptosporidium parvum, Giardia lamblia
• Weight: 18.5 oz
• MSRP: $150

The Seeker+ 6L Gravity Kit will be sold directly at HydraPak.com and through specialty outdoor retailers across the U.S.
