Budget-Friendly Innovation Meets Practical Limitations
Polyfit's second-generation rucking pack brings a patent-pending side-loading system to the budget category at $69.99. The question isn't whether it's clever—it's whether the design choices work for real rucking miles.
A solid entry-level ruck with genuinely useful side-loading access. Works well for smaller to average builds, but size constraints and basic materials keep it from competing with premium options.
Best for: Budget-conscious ruckers with average to smaller builds

Durability
The Polyfit 2.0 uses standard rucking pack construction without the bombproof materials found in higher-tier options. At 1.7 pounds empty and a $70 price point, you're getting functional durability rather than lifetime-warranty toughness. The internal buckle system that secures plates shows promise, but we'd need to see this pack survive a full training cycle before vouching for its longevity.
The material spec lists "cast iron," which appears to be an error referring to compatible plates rather than pack construction. Expect typical synthetic fabrics at this price point. The side-loading zipper takes repeated stress during plate changes—a potential weak point that budget packs often struggle with over time.
Comfort
Polyfit built this pack for efficiency over luxury. The padded straps and breathable back panel deliver adequate comfort for standard ruck sessions, but don't expect the ergonomic refinement of dedicated fitness packs. The compact, low-profile design keeps weight close to your back—good for posture and load stability.
The fit range is the biggest limitation. Polyfit claims XS to Large compatibility, but openly admits XL+ frames and taller users (6'0" with broad builds) will find it snug. That's a significant portion of the rucking community left out. If you're on the larger end of average, check their sizing photos carefully before buying.
Features
The side-loading system is the star feature here. Instead of top-loading your plates and fishing them out post-ruck, you access from the side—genuinely faster and more convenient. The internal buckle keeps plates locked during movement, addressing the shifting problem that plagues cheaper rucks.
Capacity tops out at 40 pounds across plates up to 10x12 inches. That's enough for most training progressions but may limit advanced ruckers. Compatibility with Polyfit's own plates and standard cast iron options gives you flexibility. The minimal design sacrifices external pockets and organization—this is a weight carrier, not a daily pack.
Value
At $69.99, the Polyfit 2.0 undercuts most dedicated rucking packs by $30-80. You're paying for innovation (the side-loading patent) at a budget price point. For beginners testing whether rucking fits their routine, that's reasonable value.
The tradeoffs are real: limited size range, basic materials, no premium features. Compare this to the $150+ category where you get lifetime warranties and bomb-proof construction. Polyfit positions itself as the smart entry point—and for smaller-framed ruckers or those unwilling to invest heavily upfront, it delivers. Just understand you're buying function, not legacy.

Frequently Asked Questions
What size weight plates fit the Polyfit 2.0?
The pack accommodates Polyfit-branded plates and standard cast iron rucking plates up to 10x12 inches, with a maximum total load of 40 pounds.
Will this pack fit someone 6'2" with broad shoulders?
Polyfit specifically warns that XL+ frames and tall users over 6'0" with broad shoulders or chest may find the fit snug. Check their sizing reference photos before ordering if you're on the larger end.
How does side-loading compare to top-loading rucks?
Side-loading lets you insert and remove plates without unpacking the entire ruck or reaching deep into a top compartment. It's faster for plate changes during workouts or training progressions.
Are weight plates included with the backpack?
No, plates are sold separately. The pack works with Polyfit's own plates or any cast iron rucking plates that fit the 10x12 inch maximum dimensions.
Is the Polyfit 2.0 durable enough for daily rucking?
At this price point, expect functional durability for regular training rather than lifetime bombproof construction. The side-zipper and buckle system are potential wear points to monitor over extended use.
