When hiking, water is a non-negotiable essential for survival. However, the longer your trek in the backcountry, the heavier and more cumbersome carrying several days' worth of drinking water becomes.
At Valor Tactical Store, we review the Hydrapak - Flux + 1.5L Filter Kit a game-changing piece of outdoor tactical gear designed for serious backcountry adventurers. Featuring an integrated hollow-fiber filter, lightweight collapsible design, and high durability, this system lets you safely purify water directly from natural sources on the go.
What is the Hydrapak Flux + 1.5L Filter Kit?
The Hydrapak Flux + 1.5L Filter Kit is a high-performance soft bottle equipped with an integrated filtration cap. Engineered for multi-day hiking, trekking, and backcountry outdoor survival, it bridges the gap between hard plastic water bottles and flexible hydration reservoirs—offering maximum packability, rugged durability, and instant access to clean drinking water.
Hydrapak Flux + 1.5L Filter Kit: Performance Breakdown
1. Filtration Performance & Water Quality
The Flux + Filter Kit features a 0.2-micron Hollow Fiber Filter capable of removing 99.9999% of harmful waterborne bacteria, protozoa, microplastics, and sediment from natural freshwater streams and lakes.
- Field Test Efficiency: When filled from murky natural water sources, the Hydrapak Flux purifies water in seconds. Simply squeeze the flexible bottle, and clean, odor-free, clear drinking water flows instantly within 30 seconds—delivering exceptional field filtration performance.
2. Premium Materials & Heavy-Duty Durability
Crafted from Thermoplastic Polyurethane (TPU) and high-grade elastomeric materials, the bottle body is engineered to withstand harsh trail conditions.
- Dual-Layer Laminate Construction: Unlike typical flimsy soft bottles, the dual-layer TPU body combined with radio-frequency welded seams gives the Flux bottle superior puncture and abrasion resistance against sharp rocks, rough gravel, and accidental drops.
3. Lightweight & Compact Portability
Weight and pack volume are crucial factors for long-distance backpackers:
- Ultralight Weight: The entire 1.5L system weighs only approximately 142 grams (5.0 oz).
- Space-Saving Design: When empty, the bottle rolls up flat to fit inside side pockets or travel packs without taking up valuable gear volume.
- Bail Handle: Features a flexible, heavy-duty handle for comfortable hand carry or easy attachment to backpack compression straps using carabiners.
4. Simple Field Operation
Using the Hydrapak Flux + 1.5L Filter Kit involves a simple 3-step process:
- Scoop: Fill the soft bottle directly from a river, stream, or lake.
- Cap: Secure the integrated hollow-fiber filter nozzle cap.
- Squeeze: Gently squeeze the soft bottle body to drink directly or push purified water into cookware and hydration bladders.
Verdict: Is the Hydrapak Flux + 1.5L Filter Kit Worth It?
The Hydrapak Flux + 1.5L Filter Kit stands out as a top-tier choice for hikers seeking a fast, reliable, and ultralight water purification system. While priced slightly higher than standard soft flasks, its dual-layer TPU durability, rapid flow rate, and long-term reliability offer exceptional value for outdoor enthusiasts.
