I’ve been searching for a high volume but light rucksack for possible treks in Northern Scandinavia and/or Greenland. There’s a chance that I might be able to do these in a couple of years time if I’m lucky. These sort of treks require 7-10 days of food, which takes up a fair bit of space, hence the need for a 70 litre rucksack.
I came across the Exped Thunder 70 recently and it looked just the job. Chuck in a discounted deal and I pulled the trigger. It’s very well specified and put together, but weighs a very reasonable 1.6kg (verified on my scales). I paid €220 (£166), which is good value for a quality rucksack.
The adjustable back system means that the fit can be adjusted precisely. I loaded it with a couple of sleeping bags and it seems to carry well. There’s a substantial hip belt which fits nicely. The actual sack itself is a single compartment with a top opening. However, the main sack can be accessed by twin vertical zips to make it into a panel loader. While not strictly necessary, it’s a nice feature.
There are stretch hip belt pockets as well as stretch side and back pockets. The material for these seems to be a bit more robust than average. The double lid pocket is a good size with external access as well us under the lid. Inside, there’s a hydration sleeve with port exits.
It’s a very well thought out pack with some good details. Most of the straps have neat Velcro keepers and metal Rapide hooks rather than plastic side release buckles. The side compression straps should help to control the volume of the sack for smaller loads. All in all, it looks a pretty good pack. Hopefully, I’ll be able to try it out soon.
