Design & Build Quality
The NEMO Persist backpack is built to handle tough mountain adventures while keeping comfort in mind. Every part of the pack is designed to be durable, functional, and environmentally friendly.
CERO™ Fabric: Strong, Water-Resistant, and Sustainable
The exterior of the Persist is made from CERO™ fabric, a fully recyclable material that outperforms traditional backpack fabrics. This 300D/900D ripstop weave makes it highly resistant to tears and abrasions, ensuring it can handle rough terrain. It is also solution-dyed, which reduces water waste during production. One of its standout features is its high water resistance—up to 20 times more than standard fabrics. This means your gear stays dry even in wet conditions.
CCubed™ Cushioning: Comfort and Moisture Control
Carrying a heavy load is easier with CCubed™ cushioning, a recyclable foam alternative that provides excellent padding. It is placed on the shoulder straps, waist belt, and back panel, helping distribute weight evenly. The wraparound DryWing™ back panel uses this same cushioning to wick sweat away from the body. This helps keep you dry and prevents overheating, which is crucial during long hikes or climbs.
Ergonomic and Thoughtful Design
The wide, flexible shoulder straps conform to your body for a better fit. They are reinforced with CCubed™ cushioning, making them both comfortable and supportive. The padded waistbelt helps take pressure off your shoulders and also features zippered storage pockets. One of the best features is the tuck-away water bottle holster, which keeps your bottle secure and within easy reach—something many packs struggle with.
Built for Tough Adventures
This pack is designed to handle rock, snow, and ice without compromising durability. Compression straps and universal attachment points allow you to secure extra gear like trekking poles, crampons, or a sleeping pad. The bright orange tightening straps make adjustments easy, even in low light. Whether you’re hiking, climbing, or camping, the Persist is built to perform.
In short, NEMO has created a pack that balances durability, comfort, and sustainability. It is strong enough for extreme adventures while keeping you dry, cool, and comfortable.
Storage & Accessibility
The NEMO Persist is designed for efficient packing, quick access, and smart storage solutions. Whether you’re on a multi-day trek or a fast-moving adventure, the pack ensures that your gear is well-organized and easy to reach.
Spacious 45L Capacity
With 45 liters of storage, the Persist strikes a balance between capacity and compactness. It’s large enough to carry essentials for multi-day trips without feeling bulky or overwhelming. The main compartment is top-loading with a draw-cord closure, making it easy to pack and secure gear.
Quick Gear Access with Side Zipper
One of the best features is the vertical side zipper, which provides instant access to the main compartment. This eliminates the hassle of digging through the top to reach buried items. Whether you need a jacket, a snack, or a piece of gear, you can grab it quickly without unpacking everything.
Removable Top Pocket Lid
The top lid offers extra storage for quick-access items like maps, gloves, or a headlamp. When weight savings are a priority, it can be completely removed, making the pack lighter without compromising functionality.
Smartly Placed Pockets for Easy Organization
The Persist has multiple pockets that help keep gear organized:
- Shoulder strap pockets: Zippered compartments on the straps hold small essentials like a GPS, snacks, or a phone.
- Padded waistbelt pockets: Secure zippered pockets on the hip belt provide quick access to items like energy bars, a multi-tool, or a small camera.
- Tuck-away water bottle holster: This unique feature keeps a water bottle secure without bouncing around. When not needed, it folds away neatly.
External Gear Storage & Customization
The pack includes three compression straps and two universal attachment straps, allowing you to customize how you carry gear. Loops and lash points on the exterior make it easy to attach:
- Trekking poles or an ice axe
- A sleeping pad or tent
- Wet gear that needs to dry on the move
The bright orange tightening straps are easy to locate and adjust, even in low light. This makes it simple to secure gear on the go.
Performance in the Field
The NEMO Persist isn’t just well-designed on paper—it excels in real-world conditions. After testing it on a week-long mountain trip with a 20–30 lb load, it proved to be one of the most comfortable and functional packs available. Whether hiking, climbing, or trekking through rough terrain, this pack delivers on comfort, stability, and durability.
Exceptional Comfort & Fit
Carrying a fully loaded pack for long distances can be exhausting, but the Persist remains exceptionally comfortable thanks to CCubed™ cushioning and an ergonomic design.
- The wide, flexible shoulder straps contour to your body, reducing pressure points.
- The padded waistbelt distributes weight evenly, preventing strain on the shoulders.
- The wraparound DryWing™ back panel keeps airflow moving and wicks away sweat, helping you stay cool and dry.
Even after hours of hiking, the pack never felt overly heavy or uncomfortable, which is rare for a pack in this size range.
Load Distribution & Stability
One of the biggest challenges of carrying a 20–30 lb pack is keeping the weight balanced and stable. The Persist handles this exceptionally well:
- Compression straps keep the load tight and prevent shifting.
- The hip belt stays snug and doesn’t loosen over time.
- The tuck-away water bottle holster is incredibly stable—unlike other packs where bottles tend to bounce or fall out.
This stability is especially important on technical terrain where sudden movements or shifting loads can throw off balance.
Durability & Weather Resistance
The Persist is built to handle rock, snow, and rain without issue.
- The CERO™ ripstop fabric is tough and abrasion-resistant, perfect for scrambling over rocks or brushing against rough surfaces.
- Solution-dyed materials make the fabric up to 20x more water-resistant than standard fabrics, keeping gear dry in damp conditions.
- Reinforced stitching and durable zippers ensure long-term reliability.
After days in the mountains, the pack showed no signs of wear, proving its durability in harsh conditions.
Usability & Versatility
Every feature of the Persist is designed with real-world use in mind:
- Bright orange tightening straps make adjustments easy, even in low light.
- Side zipper access lets you grab items without unpacking everything.
- Plenty of external loops for attaching gear like trekking poles or a sleeping pad.
It’s a pack that adapts to different environments, whether you’re hiking in hot weather, climbing in snowy conditions, or navigating rocky trails.
