Last year I was fortunate enough to get my hands on a pre-release Berghaus Bioflex Light 35 rucksack. It was an absolute delight tearing open the packaging to reveal the Atlantic Blue pack I was soon to fall in love with.

I should perhaps point out at this stage that yes, I am a female and have a ‘mens’ pack. At 5’6, I have a long torso and short legs meaning that for rucksacks I have to go for the ‘mens’ fit instead of the ‘ladies’ fit. This isn’t just specific to Berghaus but in my experience it applies to all brands of rucksack. ‘Mens’ and ‘ladies’ fit is just a label Berghaus have used instead of the gender neutral ‘medium’ or ‘small’ (but that’s a debate for another day!).
The Bioflex technology is an innovate idea focused on a free-moving hipbelt for optimum comfort and fit and I am very, very impressed. To date I have used this rucksack for three different types of activity.
1) Trek to Everest Base Camp
12 days of hiking in the stunning Everest region of Nepal was probably one of the best test runs I could do for this rucksack. I have always used Berghaus rucksacks for hiking trips and the difference between the Bioflex Light and the previous ones I have used is black and white.
– The hip belt is wide and soft and the padding feels like it moulds to your hips (almost like memory foam), which makes the free moving part of the belt incredibly comfortable even when carrying a fairly heavy load.
The Berghaus website says “The waist belt is attached to a BIOFLEX® Light pivot; this allows the pack to move with you as you walk providing a higher level of carry comfort and weight transfer.” This is no exaggeration; it is exactly what the Bioflex system does and my opinion is that this system made each step easier, particularly when hiking at altitude where carrying even a small load can feel arduous.
With this being my first major use of the rucksack I did come across some teething problems. Adjusting the shoulder straps and back system for comfort took some playing around with and at times people pointed out that the rucksack was leaning left or right where I had over tightened one or the other shoulder strap (although despite this, at no point did I feel unbalanced- possibly due to the Bioflex system).
2) A walk in the hills, Lake District
A month after returning from EBC I was out in the Lakes with some friends for a crisp winter walk (read here for the story). The Bioflex Light came with me again, this time loaded with gingerbread, hot chocolate and other essentials for the hills. By this point 12 days of hiking in Nepal had got me totally used to the feel of the rucksack and I had adjusted the system to fit me like a glove. It was like I was hiking without any kind of pack. Weightless, comfortable, cosy.
– The Bioflex Light is a 35 litre capacity and is perfect for me – I like to have plenty of room in my rucksack so it’s easy to dig around in, and to have the option to help lighten other people’s loads if required. It looks larger than 35 litres on the inside, yet smaller from the outside (I’ve managed to use it as hand baggage on multiple occasions with no problems).
One of the things I adore about the Bioxflex light are the mesh zip pockets on the hip belt. As soon as I start walking I get a runny nose so one pocket fits a pack of Kleenex and the other is the perfect size for sweets! The side pockets are roomy too, easily fitting a 1-litre bottle into each.
3) Introduction to Scottish Winter Mountaineering
I love trekking and have been doing it for almost 6 years but this year it was time to take things up a notch and try my hand at mountaineering. The Bioflex Light travelled up to Scotland with me (Easyjet didn’t even question the size of it for hand baggage) and new skills were learnt in Glencoe with JCG Expeditions.
Being nimble but sure-footed in the Scottish hills in winter is essential and carrying a cumbersome rucksack would be a sure-fire way to losing balance and possibly sustaining a serious or life threatening injury. The Bioflex Light reigned supreme again, hugging my body and to a degree, keeping me warm on the chilly winter days.
-The only possible drawback I can seee to this rucksack are the two small buckle clips that close the main hood are quite fiddly to undo and clip up again. I found I had to take my gloves off to do it, which in a winter scenario is a time waster and depending on the conditions, possibly risky to your fingers (particularly if you dropped a glove in the meantime). I also wonder how robust they are, given their size. Only time will tell.
There is a large front pocket under the bungee cord which is made of the same soft, stretchy fabric for the side pockets. There is a small hole at the seam of the side pocket where I suppose I caught it on something. This gives me some cause for concern about whether the other areas might end up with a hole and I’ll lose something from them.
Apart from the questionable fabric mentioned above, it’s great to see Berghaus returning to using good quality, water resistant (rip stop?) fabric for this rucksack. The Bioflex Light has renewed my faith in the brand, after it had previously been shaken by the quality in the Freeflow packs dropping below that which I would consider acceptable (to the point where I wrote an email of complaint to the company). I’m pleased that things are on the up and I will now consider Berghaus for gear going forwards.
As with most hydration systems, the inner pouch isn’t long enough to fit the older version of the CamelBak (Omega) without it poking out from the elasticated top. It really makes no difference to the function, weight bearing or appearance but it’s just something that bugs me. I am yet to test it with the newer version of the CamelBak (Antidote), which is shorter and fatter, but I suspect this will fit much nicer.
It’s a real pleasure to find a rucksack in my favourite colour!
The real test for this rucksack will be on Mount Kilimanjaro this May. It will be my third ascent of Kili. I used a Karrimor pack on my first trip, Berghaus Freeflow on my second and the Bioflex Light will join me on my third ascent. Being able to compare the load bearing at altitude on a trek I’ve done twice before will be when I can say for sure what I think of it.
Big thanks to Berghaus for creating, to date, the best rucksack I have ever used.
