For many ultralight hikers, the “holy grail” of gear is a backpack that balances weight with structure. Finding a pack that weighs just over a pound but still includes a frame is no easy task.
In my latest video, I take a deep dive into the 2025 redesign of the 3FULGear Tutor. Originally released in 2017 and recently brought back with modern updates, this 35L pack aims to bridge the gap between frameless minimalism and load-bearing comfort.

Technical Specifications
The Tutor is designed for those who have already dialed in their gear list and are looking for a streamlined, lightweight carry.
- Weight: ~650g (1.43 lbs) for the medium size.
- Capacity: Total 35L (25L main compartment, with additional space in the front mesh, side pockets, and hip belt pockets).
- Materials: * Main Body: 70D Nylon—flexible and lightweight.
- High-Wear Areas: 210D Grid Nylon with UHMWPE (Dyneema) on the bottom for improved durability against rocks and debris.
- Support: Internal carbon fiber rods (extremely thin, similar to coat hanger wire) paired with a foam back panel.
Key Features & Field Performance
The Frame System
One of the most surprising elements of this pack is the carbon fiber frame. Despite their thin profile, these rods effectively transfer weight to the hips. While the pack is rated for 25–30 lbs, I’ve found that it performs best when kept under 20 lbs. It handles 25 lbs for short stretches, but for long-distance comfort, staying lightweight is key.
Minimalist Storage
The main compartment is a single “ocean” of space. There is no hydration sleeve, internal key clip, or hose port. This simplicity keeps the weight down but requires a pack liner (like a Nylofume bag) as the material is not waterproof.
The exterior features:
- Breathable Front Pocket: A fine-weave fabric that allows wet gear to dry while remaining durable against thorns.
- Side Pockets: Capable of holding two water bottles each, with adjustable elastic tensioners.
- Roll-Top Closure: Uses snaps rather than velcro or stiffening bars.
The Hip Belt
A standout feature is the pull-forward adjustment system, which allows for better leverage when tightening the pack. The belt also features four adjustment points to better accommodate the natural curve of the hips.
Pros & Cons
What works well:
- Weight-to-Value: It is incredibly lightweight and inexpensive for a framed pack.
- Clean Design: Unobtrusive and functional without unnecessary “bells and whistles.”
- Comfort: Excellent weight transfer for loads under 20 lbs.
Points for improvement:
- Back Ventilation: The foam panel can get quite warm during high-exertion hiking.
- Pocket Hardware: The hip belt zippers use ribbon pulls which can be difficult to grip with gloves; a simple cord-and-knot replacement is a recommended DIY fix.
- No Shoulder Pockets: You’ll need to add your own if you prefer easy access to snacks or electronics on the go.
Final Thoughts
The 2025 3FULGear Tutor is a solid choice for experienced hikers who prioritize a “light and fast” approach. If you are a summer hiker or a weekend warrior with a sub-10lb base weight, this pack offers the structure you need without the weight penalty of a traditional internal frame.
