Nathan Pinnacle Soft Flask | 14oz | Sage Green/Reflective Silver

When you're covering serious miles on foot, ultralight hydration doesn't have to mean sacrificing durability or comfort. The Pinnacle Soft Flask from Nathan is engineered for runners, hikers, and endurance athletes who demand a lightweight water carrier that won't leak, won't slow them down, and won't let them down when conditions get tough. This collapsible flask delivers dependable hydration storage without the rigid bulk of traditional hard-sided bottles, making it the ideal companion for trail runs, ultramarathons, gym sessions, and backcountry adventures where every ounce counts.

• Lightweight soft construction collapses as you drink, reducing pack volume and dead weight throughout your activity
• Durable, food-grade TPU material resists punctures, tears, and degrades gracefully under UV exposure and temperature extremes
• 500ml (16.9oz) capacity strikes the perfect balance between hydration range and packable size for day trips and long efforts
• Wide mouth opening enables easy filling, rapid cleaning, and convenient addition of ice cubes or electrolyte powder
• Secure, leak-proof valve cap engineered to prevent accidental spills in packs and gear bags during transport and storage
• Graduated volume markings help you track fluid intake and plan hydration strategy during extended outdoor pursuits
• Compatible with most Nathan hydration packs, running vests, and waist belt systems via integrated attachment loops
• Easy-to-grip body texture prevents slipping when wet or sweaty, ensuring confident handling on technical terrain or during intense efforts

In real-world conditions, the Pinnacle Flask excels across diverse scenarios. During intense summer trail runs when thermal load demands frequent hydration breaks, the collapsible design keeps your pack light and unbalanced weight minimal. On multi-day backpacking trips, you can refill at water sources and compress the empty flask to reclaim precious pack real estate. The TPU construction shrugs off rocky terrain contact and freezing overnight temperatures without becoming brittle or cracking. Ultrarunners appreciate the ability to carry multiple flasks across aid-station-sparse courses, while gym enthusiasts value the compact post-workout storage and dishwasher-safe convenience.

The Nathan Pinnacle Soft Flask is engineered for serious athletes and outdoor enthusiasts who refuse to compromise between weight savings and reliability. Whether you're training for a 100-miler, exploring remote alpine terrain, or simply optimizing your daily running kit, this flask delivers dependable hydration performance in a package that won't weigh down your adventure.
