adidas Unisex Classic 3Bars Backpack in Olive Strata/Black
Product description
What it is
The adidas Classic 3Bars Backpack is a medium‑size daypack built for everyday use, from commutes to gym trips. It’s made from recycled polyester and features a practical layout with a main compartment and a front zip pocket for smaller essentials. The unisex design and neutral colourway of olive strata with black accents make it a versatile option for a range of outfits and contexts.
What it offers on paper
On the measurements front, the pack sits at 15 cm wide, 31 cm tall and 44 cm long, with a stated volume of 27.5 litres. The materials are 100% recycled polyester for both the outer fabric and lining, with padding in polyethylene. This combination suggests a lightweight, durable shell with a soft interior, suitable for daily use, light belongings and school or workplace loads.

How it feels to use (practicalities and pitfalls)
On the move, the 27.5 L capacity is handy for carrying a laptop or tablet alongside books or a gym kit, though it isn’t oversized. The front pocket adds quick-access storage for keys, cards or headphones, keeping the main compartment uncluttered. If you’re mindful of weight, the recycled materials help keep things tidy without overloading the shoulders, but as with many packs, the lack of visible sternum strap or hip belt means it’s best for lighter, daily carry rather than heavy loads or long hikes.
What stands out


The mainstream appeal of this adidas pack is its understated look and practical layout. The olive/black palette remains easy to pair with most outfits, while the 27.5 L capacity offers a balance between compactness and usable space. For those who prioritise sustainability, the use of 100% recycled polyester for both shell and lining is a meaningful detail in the value equation, especially if you’re comparing to similarly styled backpacks that use virgin fabrics.

What doesn’t convince as strongly
If you regularly carry bulky items or require reinforced support, this backpack may feel a touch modest. The absence of features such as a padded laptop sleeve in the primary compartment or adjustable back panel could limit comfort for heavier loads or all‑day wear. It’s also not the largest option in the daypack category, so those needing more volume or dedicated tech pockets might prefer a bigger model.
Who it’s for
This backpack looks to suit daily commuters, students or casual users who want a reliable pack with a clean silhouette and a reasonable capacity for books, a notebook, a water bottle and a light gym kit. It’s particularly appealing if you value a minimalist aesthetic and a compact footprint that still handles a day’s essentials.

Who it isn’t for
If you need substantial padding, ergonomic support or a highly organised interior with multiple compartments, this model may not be the best fit. Likewise, if you routinely carry heavier gear or require a dedicated laptop sleeve with security features, you might want to explore options with more robust protection and structure.


When it makes sense to buy
Consider this backpack if your day-to-day tasks involve carrying a handful of items, a small planner or a laptop/tablet within a modest size envelope, and you prefer a straightforward, low‑fuss design. It’s sensible to compare against other compact backpacks that offer similar volume but with more tech-friendly pockets or a more rigid back support system. This model serves well as an economical, durable, daily carry option rather than a specialised, niche backpack.

When you might want to pass
If you prioritise advanced organisational features, heavier duty materials, or active use like all‑day hiking, the simpler interior and modest padding may feel limiting. In such cases, a pack designed for higher load or with enhanced comfort features could deliver better long‑term value.
What to check before buying
- Confirm you’re happy with 27.5 L capacity for your typical load.
- Consider whether a padded laptop sleeve or reinforced back panel is a must for you.
- Check the care instructions for the recycled polyester fabric to ensure it aligns with your cleaning routines.
- Inspect the overall build and zips for smooth operation, since daily use can reveal stitching wear or zipper stiffness over time.

How it compares in use

Compared with larger, more feature‑rich backpacks, this model leans into simplicity and portability. If you value a low profile and quick access front pocket, the layout will feel sensible for everyday errands or light study sessions. For those who want dedicated compartments or premium back support, you may find this falls short and should explore alternatives that add structure and protection without dramatically increasing weight.
Final verdict
Is it worth it? For buyers seeking a modest, well‑made daily backpack with a sustainability angle and a clean look, this adidas option can be a practical, value‑oriented choice. It won’t replace a purpose‑built work bag or a hiking pack, but it fits well into a pragmatic, everyday carry routine. If your needs are light to moderate and you value a fuss‑free silhouette, it’s worth considering.
