There are mainly two offers from Sandqvist: a mid-range one (around €200) and a more recent entry-level one (less than €150).
The latter is an excellent alternative to other entry-level brands such as Eastpack or Herschel. It offers original and elaborate designs, as well as a very good quality/price ratio. The lifespan of your bag will not be eternal, however, and the synthetic materials used are not the most beautiful of the brand.
It is from its mid-range that we find all the interest of Sandqvist: durable materials and finishes, with a special mention for the cordura parts which resist excellently to friction. The cotton canvases used have deep colors and very beautiful reliefs.
Concerning the leather pieces offered for more money, they will hold up well even if the leathers lack charm: do not expect the most beautiful patina, nor very good aging over time. These are also corrected leathers (sanded and coated) which can be difficult to nourish and maintain.
