Fast delivery. The backpack is simply amazing! Spacious and well-made. The seams on the zippers and pockets are neat. The material inspires confidence in its waterproof properties. One wish would be to add a drawstring strap between the shoulder straps or on the chest, but that's just nitpicking. Overall, an excellent option for everyday use or going to the gym. I definitely recommend both the seller and the product.

Excellent product😍 Highly recommend for purchase💙💚❤ This is my second time ordering, as a gift for a friend. She is thrilled.

The bag is quite spacious, which I liked, and it has adjustable volume for Aeroflot.

Very pleasant to the touch, comfortable to wear, and spacious.

Good quality. I recommend it 😍 Super backpack. I'm delighted 😍🌸

Simply an excellent backpack. The quality is top-notch, not a single loose thread. The interior is made neatly.
It looks really waterproof. From the pleasant bonuses, USB. The internal wire is stored in a special pocket behind a lock.
I give it a solid five-star rating. Great item. It's pleasing to the eye and the price is very reasonable.

The best backpack! It's heavy, but there's no other way.

very good 👍 and convenient

The backpack is very well-made. It has many compartments and external pockets. It's waterproof and doesn't stain. It's large and spacious. I bought it to go to the gym. Everything fits inside, and it doesn't look bulky; it's neat and tidy. It looks much more expensive than it actually is.

Excellent backpack. The quality was impressive.

Well-made. It's small, even with the top unfolded. Twenty liters, no more. But - nice and beautiful. Hardware, delivery time, materials - all good.
Thank you!

perfect, the child is delighted

Excellent waterproof backpack
turned out to be more than I thought.
but still stylish :))
Thank you 💜

Nice bag, well-made, liked it!

very cool backpack, I recommend it!

I confirm, the backpack is very cool!!! The size is not small, if it's critical for you, measure it.

Nice material and looks great, fits the laptop without any problems. So far no complaints, but we need to look further, maybe the dog on the zippers will fray or tear where the fabric is. Tested for water resistance - indeed, water doesn't stay back, but not like in the video where not a single drop was left.

The backpack is super, interesting material, unclear, fashionable backpack for everyday use.

Gifted to a girl. She is delighted with the color, material, and size!

A brand-name item, beyond praise, I give 10 stars instead of five!!!

It's an incredible backpack! Super spacious and of VERY GOOD quality.
