Hydrapak Breakaway Muck

When the trail gets rowdy, your hydration shouldn't falter. The Breakaway™ Muck 15oz bottles deliver even the most challenging conditions. We've all been there – dive into a section of gravel or rough trail and have a bottle eject itself from your cage...leaving you high and dry (literally).

Engineered specifically for mountain bikes with tight spaces, this compact 15oz size fits where other bottles can't—perfect for dual-suspension frames with limited cage space. It's a lightweight single-wall design, ready for the flow!

The MuckGuard™ Advantage

The innovative flip-up MuckGuard™ is your defense against trail debris, protecting the valve from mud, dust, and grit that would sabotage your bottle and flavor. 

Highlights:

• High-Flow Surge™ Technology: Self-sealing valve delivers maximum water volume with minimal effort, then automatically closes to eliminate drips and spills—even on the roughest descents
• Ultra-Lightweight Design: Single-wall construction sheds unnecessary grams while maintaining durability
• Ergonomic Grip Groove: The unique contoured shape and flexible material create a secure hold during intense efforts
• Frame-Friendly Size: The compact 15oz capacity is specifically engineered to fit smaller frames and full-suspension bikes where standard bottles won't
• Easy Maintenance: Two-piece Surge™ Cap disassembles with a simple twist and pull for thorough cleaning, then reassembles in seconds (dishwasher safe)

Clean fit, pure flow, no compromise—that's the Breakaway Muck.
