Yesterday i bought a bit bigger 30l backpack becouse the 20l are a bit small for >5 day trips. To test it i just decidet to fill it with some heavy stuff and travel to the next small mountain and make a small hike.
Surisan is the next mountain to my place and i already know it from a rock climbing trip with my friends but i never hiked there. Compared to the national parks it was less crowded and the batelfield charme is much stronger when you hike around some army bases.
In the end the mountain was awesome and the backpack is worth his money.
