Bought for my 7 year old daughter and it's a perfect size, not too small and not overly big. Plenty of space inside the front pocket for her lunch. And loads of space in the main compartment which includes a couple of smaller pockets. Extremely happy with my purchase(only the 4th attempt at getting a perfect rucksack for school!) would definitely recommend! ### ⭐⭐⭐⭐⭐ perfect for my 5 year old *by K***Y on Reviewed in the United Kingdom on 17 September 2015* My daughter aged 5 (year 1) absolutely loves this backpack! It's the perfect size for her with growing room too.There's a front pouch where she keeps her "art" from the school day and other "treasures"! Then a front zipped area which is insulated which is the perfect size for her yumbox and a freezer pack and the back compartment for her PE kit - she likes to keep letters from school etc in the sectioned area within this part too. It's big enough to fit everything in but it doesn't swampHer like lots of other bags do for this age! ### ⭐⭐⭐⭐⭐ sturdy and durable *by A***E on Reviewed in the United Kingdom on 21 October 2016* I got this backpack for my 7 years old daughter who's in P3, she loves it and I do to. It is a really quality product, sturdy and durable, with good zips, perfect size for primary school and with plenty of pockets, even inside, to keep the child's belongings nice and tidy.I really sincerely recommend it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/96043162-unisex-kids-mini-preschool-all-in-one-backpack-for-toddlers](https://www.desertcart.vn/products/96043162-unisex-kids-mini-preschool-all-in-one-backpack-for-toddlers) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-24*
