Quick Take
Score: 8.7/10 | REI's house brand Tarn 12 Kids Pack hits a sweet spot: Bluesign-certified recycled materials, decent ergonomics, and REI's member benefits all for $40. It's not quite as refined as Osprey or Deuter, but at 25-30% lower price with similar safety certifications, the value proposition is strong.
What We Evaluated
This review uses the R3 Kids Backpack Methodology v1.0.0, evaluating backpacks across five pillars: Safety (30%), Efficacy (30%), Value (20%), Usability (15%), and Sustainability (5%).
Safety Analysis (30% weight)
REI Co-op products use Bluesign-approved fabrics, the same third-party certification as Osprey and Deuter. This covers harmful substances testing including heavy metals, PFAS, and problematic chemicals throughout manufacturing.
The Tarn 12 is made from recycled polyester using PFC-free DWR for water resistance - no PFAS forever chemicals. Hardware is standard nylon and metal without vinyl components.
REI has strong corporate standards around product safety, though they don't publish explicit lead testing results for individual products. The Bluesign certification provides confidence, but families seeking documented lead-free testing specifically should note this gap.
One advantage: REI's satisfaction guarantee means you can return the pack if any safety concerns arise. The company has historically been responsive to product safety issues.
Performance & Efficacy (30% weight)
The Tarn 12 features a contoured foam back panel with breathable channels. It's not as sophisticated as Deuter's Airstripes or Osprey's AirScape, but provides reasonable comfort and airflow.
Padded shoulder straps are appropriately sized for kids with adjustable sternum strap included. The straps are slightly thinner than premium options but adequate for the 12L capacity and intended lighter loads.
At 12 liters, this pack suits ages 5-10 for typical school and adventure use. The single main compartment design is simple but functional. Front zip pocket provides quick access storage. Dual side water bottle pockets are stretchy mesh.
Weight is 0.9 lbs empty - slightly heavier than Osprey but reasonable for the price point. The pack sits well on smaller backs without extending too low.
The ergonomics are good but not exceptional. For everyday school use, the Tarn 12 performs well. For serious hiking with heavier loads, the premium brands offer better weight distribution.
Value Assessment (20% weight)
At $39.95, the Tarn 12 is positioned between budget options and premium outdoor brands. REI members get additional value through:
- 1-year satisfaction guarantee - full return for any reason
- Lifetime membership benefits - repair services, gear trade-in programs
- Member dividends - typically 10% back on REI brand purchases
The pack itself is well-constructed with YKK zippers and reinforced stress points. Expected lifespan is 3-4 years with normal use - not quite L.L. Bean legendary, but solid.
When you factor in REI's repair services (they'll fix zipper issues, torn seams, etc.), the total value extends beyond the initial purchase price. For REI members, this becomes one of the best overall values in the category.
Usability (15% weight)
The 12L size is appropriate for elementary ages 5-10. Simple, intuitive design means kids can use it independently without complicated features.
Zippers are easy to operate with standard pulls. The main compartment opens wide. Interior organizer pocket helps with small items. Reflective accents provide visibility.
Six color options including kid-friendly patterns. Not the widest selection, but reasonable variety. All colors maintain the simple REI aesthetic without licensed characters.
Machine washable on cold gentle cycle.
Sustainability (5% weight)
Made from recycled polyester - REI states specific percentages in product details. Bluesign certification ensures responsible manufacturing. REI's corporate sustainability commitments are among the strongest in outdoor retail.
The gear trade-in program means you can return the pack when your child outgrows it, keeping materials in circulation.
The Bottom Line
The REI Co-op Tarn 12 Kids Pack offers Bluesign-certified safety and respectable ergonomics at a mid-range price. For REI members who value the satisfaction guarantee and repair services, it's excellent value. Non-members may find the Osprey Daylite Kids worth the extra $15 for the lifetime warranty.
