Hi everyone, i’m looking for a new trekking backpack. I usually go 3/4 times per year on trekking. They usually are 5/7 days long on summer and 4/5 during winter. The conditions are never extreme (no snow or ice). I found some reviews online but i can’t find the optimal pic, i would love to hear your experience.
The backpack i’m looking for should be around 50l and carry around 14kg including water. My hikes are usually around 15/20 km per day with 600/700m difference in altitude.
I was curios to hear from you about:
- gregory stout 55
- gregory focal 48
- osprey exos 48
- deuter aircontact ultra 50
