Best cost performance

The backpack is quite presentable but leaves much to be desired; the bottle cap doesn't seal well and neither does the backpack. The fabric is very thin. My first outing with it ended with the backpack cracked and the bottle cap leaking water because it didn't seal tightly, leaving me soaked.

Shiny piece for e-skating too! We can carry our most important things - the drink - with us inside. It also fits people who are 180 cm tall and weigh 100 kg. Good quality product as described.
