Exped's Thunder Rucksacks offer a large front opening (in addition to the more traditional drawcord closure) with a full range of 'make a difference' features mounted to an excellent adjustable lightweight harness system.

Exped says: Thunder is a trekking pack with a superb weight to volume/feature ratio.

The suspension system is quickly length adjustable and provides excellent fit, torso mobility and weight transfer. Three access options to the main compartment (top, front and side loading) allow simple packing and unpacking. A large front and two side stretch pockets offer additional storage space.

A floating lid with inner and outer pockets and adjustable side compression straps increase carrying capacity for extended trips and expeditions.

Exped's Thunder Rucksacks use the same excellent adjustable harness system as the Lightning series of packs, and we can testify that its a very comfortable carry. Whereas the Lightning packs are designed to be a minimal weight the Thunder series offer the trekker a much more sophisticated and feature rich pack.

Many will like the lid which provides protection for the top of the bag and has two pockets (one internal and one external) to help you keep organised. Backpackers will like the addition of a large mesh pocket at the front of the pack, ideal for wet gear and the daisychain loops which offer endless options for securing kit to the outside of the pack.

The key feature though is the huge panel access at the front of the pack which allows you to see, pack, unpack and keep your gear organised  wherever you are and whatever you're doing. Mounted on the aforementioned harness with adjustable backlength, well padded hipbelt with mesh pockets on the hipfins the Thunder rucksacks offers comfort, convenience and flexibiity at an overall weight that's still pounds lighter than many of its peers.

Exped thunder 70

Good lid that can be raised and secured with buckles instead of clips. Ideal for someone switching to heavier gear but obviously as light as can be. If my ultralight pack from elsewhere aches in comparison then I may buy a 50 but not sure I'd need all the features from the 70 in a 50 version but then I don't see why not either. There's no other big pack that Id swap the 70.

Great pack, but feel I made the wrong decision buying it

I spent many, many, MANY, hours researching bags online before settling on this one. It could even have been days, who know. I mean, I even made an excel document!
PROS - It is well made; it opens all the way up, with 2 zips that run down most of the body, = Easy access; The side pockets are very stretchy and fit in a lot (although the material isn't very robust); Has many features; Lid; 2x waist pockets - stash pocket on the back; Its mega roomy; Using the side straps you can tighten the bag right up; Especially useful if you're only carrying a small load; There's an aluminium frame; Carry loads up to 23kg (apparently). Not sure I would want to do a long trip with 23.5kg in this pack (explained below); I like the opening and closing system of the lid (clips); It is easy to adjust to size; 2 year guarantee.
CONS - Not actually that lightweight (1586g), ok, so it isn't heavy either, but... I went for this model because at the time of purchase I felt I needed the option of being able to take heavier loads (which kind of defeats the purpose if I am aiming to go lightweight); But, I wanted that reassurance that it could carry heavier loads if needed; Exped claims that this pack (and the more lightweight Exped Lightening 60) can take loads of up to 23.5 kg which, may be true, and I don't have field testing to say otherwise... but, i have used around 15 kg in the bag, which was comfortable, but any more and I am not sure; The strap systems on some other lightweight packs look more robust, and these companies claim that the max load should be around 15-18kg; Thin shoulder straps, both in thickness of cushioning and width; Materials are lightweight, and already some are fraying and looking tired.
Overall I have had a bit of a love hate relationship with this bag. When I bought it I loved it, and many of the features I do still like, and when using the bag I STILL do like it. It's a really good bag! I feel like I have been overly harsh, but I spent a hell of a lot of time researching which bag to get and I have a nagging feeling in my mind that I made the wrong decision. I feel like I only went for it because it has the capability to carry heavier loads (which i am still unsure of). And because of this I am carrying around an extra 400 to 500g of pack weight, that I feel doesn't make that much difference. (400 to 500 grams compared to the other models I was looking at). I feel that this bag tried to fill a niche between lightweight and normal weight pack, and has left me dissatisfied. (I mean it IS still quite lightweight compared to the norm). If you are looking for a lightweight pack with a load of great features such as: a lid, a stash pocket, and two waist pockets I WOULDN'T buy this bag. Instead I would consider: GRANITE GEAR Crown 2 60 or Osprey Exos 58 or Gossamar Gear - Mariposa robic 60. You will save 400g to 500g in pack weight.
