The Berghaus Hyper 37 backpack review

I love running in the mountains and whilst I dream about being able to run in the Alps every day, the reality of living in north London is that I can’t. And the thing I love above all else, is multi-day trips or ‘fast-packing’. My definition of this, is taking as little as possible, going as light as possible and moving fast through the mountains. And I have my wife to thank for introducing me to this idea. Before I met her, my experiences had been limited to a few day-long runs in the hills, a couple of ultras (but in south east England, so not very mountainous) and one weekend spent tackling the ‘three peaks in 24 hours’ challenge with three friends.

What my wife introduced me to was the idea of running for two or three days, from cabin to cabin, through the Alps. In fact that is what we did for our honeymoon.

Philippe and Anna Gatta… and one immense challenge

So I think I can empathise, to some degree, with Philippe and Anna Gatta, who with the support of Berghaus are running over 1,000 miles along the length of the Great Himalayan Trail. Actually, Philippe is doing the whole trip while Anna, very sensibly, is running sections with him rather than taking on the whole thing.

I like to imagine that Philippe and Anna will be like Julie and I, floating along the mountain trails, catching sight of the rare mountain fauna, seeing magnificent mountains and sunsets, managing adverse conditions together and generally experiencing something life-changing and life-affirming.

Except there is a very big difference between what the Gattas are doing and what the Freemans do from time to time. The Great Himalayan Trail is NOT the Grand Tour de Mont Blanc. Not by a long stretch.

The difference between the Alps and the Himalayas

For me and Julie, setting off on a three day run around the Mont Blanc is intrepid. It is exciting and challenging and full of wonderful surprises. It is also very, very safe. One has a mobile phone signal almost all the way around Mont Blanc. There is a mountain refuge or cabin at the end of every days hike, so if you are running, you can probably stop at one for lunch and arrive at the next one in time for dinner and a bed for the night. The Grand Tour de Mont Blanc is a busy route and if you sat down for an hour you would almost certainly have a group of people walk past you. In short, you would be hard pressed to get in trouble and not have a fairly easy way out on the routes that Julie and I have run on.

Not so, the Great Himalayan Trail. This is not a tourist destination for well-heel hikers out for a day or two, aiming to walk off their fondue excesses. The GHT is a tough track through very hard mountains in an area where if you get in trouble, you are going to have to sort yourself out. Which is why Philippe Gatta and not Simon Freeman is taking on this challenge.

Philippe’s CV reads like the pages of a hybrid of Sir Ranulph Fiennes autobiography, a Boys Own adventure story and James Cracknell’s new years resolutions list. He has climbed Everest, run multi-day ultras, swum across thundering glacial rivers, wrestled bears and all with wonderful Gallic flair. If anyone is going to have a chance of running, unaided and carrying all his kit requirements for XX days, Philippe has the right credentials. Oh and Mrs. Gatta will be there at times to give him a kick in the backside if he looks like he is flagging.

You can follow the adventure as it unfolds day by day, by visiting the Berghaus Community website and I highly recommend having a read of all the updates so far (Philippe is on Day 20 at the time I am writing this). It is honest, warts-and-all, compelling stuff and really explains the utterly mind-blowing scale of what this modern-day adventurer is taking on. Here is the link.

Got the idea, now what about the gear…?

So if Gatta has the physical and mental tools to take on such an incredible task, what about the kit that he will need.

My experience is that every time I have been in the mountains, I have realized that I can take less and less with me. For the UTMB CCC race this year, I had to take the compulsory kit, but blessed with decent weather I used precisely none of it. Even at 3am, in the pitch dark, climbing a mountain alone, the only upgrade that I needed was to go from a short-sleeved merino top from ashmei to a long-sleeved base layer from The North Face. My waterproof shell, duvet jacket, waterproof trousers and so on all stayed safely packed in my bag.

But Gatta needs to be more careful. If he gets in trouble he will need to have all the kit he needs to get out of trouble or at least stay safe until help arrives and that could be a very long time. He will also be gone for an extended period and will be running at high altitude so the weather conditions will be very changeable and he needs to be able to manage that.

Given all that, Berghaus have gone to work creating a set of kit that will cover all conditions and give Philippe the security he needs. I have not tried any of the apparel or footwear, but I have been given one of the most crucial bits of kit that Bergahus has developed for Gatta – the thing he will carry all the kit in!

The Berghaus Hyper 37

I guess that in reality everything that Gatta carries on his epic challenge will be equally important and I know that he and Berghaus team have worked hard to ensure that he has everything he needs and nothing that he doesn’t. But arguably, without a really good bag, he would be scuppered because he’d just have a big pile of kit on the floor.

And ‘big’ is the word here. The kit list that Gatta has developed must be pretty extensive and that creates a need for a big bag. Certainly this is not a 90 litre monster like the rucksacks that you see unbalancing the kids doing their Duke Of Edinburgh awards events. At thirty seven litres the bag is a very interesting capacity – small enough that you would have to think about everything you take if you are going for a multi-day event – there would probably not be room for anything other than the tinyest sleeping bag for example. But it is also probably too big for a single-day race like the CCC or the Montagn’Hard, both of which I ran this year.

The bag feels just about right if you want to carry enough kit to be comfortable and yet still move light and fast. It is also extremely expandable. The stretch pockets on the front and sides of the pack seem to have no limit and the main pocket could easily accommodate a cycling helmet or crampons (although sharp spikes might be a bad idea for the very thin fabric.

The main section of the bag is a single space with a top opening, closed with a draw-string and a lid with more capacity for things that you need to have to hand.

Inside the bag there is a sleeve for a hydration bladder and a removable pad that doubles as a sleeping mat (though this is most definitely on the minimalist side of things!)

The straps are really comfortable and padded, not digging in at all, even when the bag is fully loaded and waist-strap is marvelous, being elasticated so that it fits like a glove and also with two really good-sided pockets for all the things that you need to have close to hand.

One other things that is worth noting about this pack is the system for synching the pack down if it is not full. There are just a couple of bungee cords that cross the front of the pack, incorporating the clip for the pack lid. One quick tug and everything comes together, pulling the pack tight around whatever you have in it.

And in fact that is part of the wonder of this pack. Everything is so simple. One large section. Three outer pockets with masses of capacity. A simple system for tightening the bag. Comfy shoulder straps and good-sided pockets on the waist strap. That is it. No bells and whistles (well actually there is a whistle on the chest strap, but that is to be expected).

On the other side, the Hyper 37 is a pack designed for a multi-week self-supported expedition in one of the most challenging environments – it is, in fact, big. This is not a back-pack that you would take for a day running on the trails. In fact it would probably be too big for me, for something like the CCC and of all the races in that wonderful Alpine weekend, the only race that would justify this bags load capacity would be the 300km PTL. That is only to be expected – after all the pack was designed with Gatta’s expedition in mind. And I understand that there is a 22 litre version that will be available soon alongside this bigger bag, so you can hopefully find all the benefits of the Hyper 37, just mini-er.

Berghaus have done a great job

All in all, I love this bag. I will readily admit that I am a bag fan of bags and Berghaus: for me there is no such thing as too much luggage and I never seem to have exactly the right sort of bag for everything I want to do. I love bags probably slightly more than I love stationery, and I love stationery a lot. And I love Berghaus.

I don’t buy much stuff in general but I coveted a Berghaus duvet gilet so much that I ended up with it for Christmas last year and I welcome the onset of winter so I have a chance to wear it! And my favourite back-pack is a Berghaus one that I have used for travel and multi-day expeditions without the slightest cause for complaint.

And even through the fog of all that love, I can honestly say that the Hyper 37 is a great pack. If you are looking for the ideal bag for a light and fast expedition, running for several days with the requirement to carry a fair amount of kit , food, etc, then this would be a great choice. I’ll certainly be planning some multi-day runs soon, simply to have a chance to use the bag more… well, any excuse will do really!

The Berghaus 22L Hyper Rucksack will be available March 2014 with a SRP of £70


  1. Hi Simon. It’s the Berghaus team here – thanks for taking a look at the Hyper 37! We just heard from Philippe that rats ate part of his bag while he was asleep one night – even we weren’t prepared for that eventuality…

  2. Hey Simon. This is a nice review of the pack I’m considering to get for ultralight backpacking. I’m curious about the weight of the the load you’ve put in it when you tested it. Do you think it’ll remain comfortable at 20 pounds max?

    I’m also having doubts about the durability of the pack because of the thin material they used. What are your thoughts about this?


    1. Hi Edward. Thanks for getting in touch. I have to say that I have not had huge loads in the pack but I do think that it would be fine up to 20kg. Actually if anything it is better with a heavier load because it doesn’t bounce as much. As for durability, I have thrown everything at this bag and there is not the slightest sign of damage, so I’d say Berghaus have got it pretty right.

      1. Great! I’ve also read a recent update on Philippe’s blog where he mentioned that he carried a 10kg load on this pack for his expedition. I carry a little less than that so I should be fine.

        Thanks for these tips. I might get this pack by the end of the year.

  3. Hi simon,

    I’d love to buy this bag, however I am not too confident about the long term durability. How long have you been using this bag for and what’s your opinion on long term durability as oppose to other pack such as deuter, osprey etc.


    1. Hi Zack, I have to say that I have really hammered this bag, running with it, hiking with it, using as hand luggage on flights… and it looks as good as new! Honestly I believe this is a really durable sack and if it held together for Philippe and Anna Gatta on their GHT run (which it did), it’ll cope with most things. Hope that helps.

  4. Hi Simon. I just read your review, i am considering buying one of this bags for my husband. who is 180 cm tall ( 6′) and back lenght 50 cm. do you think this will be suitable?
    also does this backpack has a good back support?
