Varusteleka is a Finnish military surplus store. They have their own “Särmä” product line aswell but other than that they’re just a retailer. Savotta, however - the manufacturer of the backpack I linked, is a very well known and highly appreciated Finnish military/hiking gear manufacturer that makes gear for the Finnish Defence Forces aswell. Their quality is absolutely top notch. I have both, Jääkäri S and Jääkäri L backpacks among their other gear aswell.
What comes to that specific online store; the descriptions actually are honest. If the product is shit it says so in the description. I’ve seen examples of that before and especially the Finnish descriptions are sometimes hilarious. I’ve bought a ton of stuff from there and everything has met or exceed my expectations.
Edit: You’re probably talking about the 202 LJK Daypack. It’ll last two lifetimes.
