I carry it for at least an hour a day and it weighs as much as a small family car.
Budget about £150 but would prefer under £100.
It needs:
Padded, comfy, non-fall down straps
Strong!
Flat base to stand it up.
A seperate laptop pocket/section
Outside water bottle holder.
Zip up outside pocket.
Pref waterproof but that isnt a deal breaker.
Not leather
Not overly work laptop carrier looking iyswim
No big logos/patterns
Not black or grey or brown coloured
Not look like I'm going for a hike!
I'm using a Nordace Sienna which is about the right size but the straps which were never great have gotten thin and twisted.
I also use a Roka rucksack but the straps are too thin to carry any weight.
Thank you!
