sweat 25% less with ventilated pack frames

[wayno]

Subsequent tests carried out at the Hohenheim Institute (source Deuter) demonstrated that athletes using the Deuter aircomfort system sweat up to 25% less than non-ventilated backpack systems, enabling better physical performance with less discomfort.

I have a Osprey Exos with a ventilated back, and I recently tested a Ferrino Boulder with a similar frame. I think they are a great innovation.

Bring back the external framed pack then, at least for summer i do find them more efficient and cooler and even I can get away with a 75 litre pack in summer

external frames are making a comeback in the states....

I've had a Tatonka "Bike 'n Hike" day pack for years and will never go back to a non-ventilated frame.

That's a really interesting result Wayno.

Overheating is my biggest risk on strenuous walks (I have MS and raising my core temperature even slightly can have "interesting" consequences) so I mostly avoid the warmer weather. But even in cool conditions I can get pretty hot and sweaty very easily. I have never tried a day pack with a ventilated back. Maybe it's time I did!

know someone who had ms. she became a vegan and all her symptoms disappeared. if she starts eating red meat or dairy her symptoms come back.

Interesting
I don't think I could persuade my missus to even try giving up meat and cheese, especially bacon.
this thread reminds me; I need to get the hipbelt for my Op-Shop Macpac finished

I will be testing out a new pack frame in the next few days that will help combat the heating issue, its designed more for the Gossamer Gear back packs but can be used on other brand packs, which im not sure yet. Ill post more on it with some images, after i have put it into its paces.

Wayno - interesting about your friend. I was vegetarian (and had been for years) when I was first diagnosed with MS nearly 20 years ago and I've only started having fish and very small amounts of meat over the last couple of years. But there's most likely a strong genetic component in my case, as my brother has MS too. MS is one of those frustrating conditions where nobody can point to a single cause - I follow the research literature quite closely though, and the knowledge about MS is increasing all the time. Treatments are improving too, I remember when there was only 1 treatment available; now there's 4 in common use and more undergoing clinical trials.

Phillipsart - I'll be very interested to see your report on the pack frame you are testing.

Meh, unconvinced by ventilated packs. I have a deuter daypack for cycling and a berghaus ventilated daypack. I think there's a a mediocre cooling effect, Especially when cycling but its not as if there's an arctic cooling breeze suddenly whistling past your back. Both types have a mesh springy sheet that interfaces with your back which gets pretty sweaty. I think the effect is overstated unless there's a substantial breeze getting to your back.
My main gripe with these packs is that they're impossible to get close enough to the back to be firm, despite the mesh sheet. This means they are quite unstable on the back. When I ride or walk with these packs they swing around, which is disconcerting especially when rock scrambling. There's no way to get them firm on the back without the pack riding up above the hips.... Difficult to describe and probably sound unconvincing.
I would definitely not get an overnight pack of this design, although it is possible to get other styles I suppose. Be aware also that the design moves your centre of gravity rearward. A problem I remember we'll from the 'Alice' packs in my army days.

Really just a matter of learning how to pack one, I notice the "Pull-back' more with a poorly packed internal frame than I ever do with an external frame.
I have managed to carry much more weight and bulk comfortable with a really good framed pack than I would ever attempt with an internally framed pack. Biggest load I ever carried was 3 jerrycans of petrol on my old CampTrails frame with the load shelf and with my stuff as well although it was only a short hike of about 8 k's
Don't confuse a "REAL" frame with the Australian Armys torture racks, Ever tried to carry a "10" Set with 2 spare batteries plus all your gear. No wonder my back is buggered.
Alice frame isn't all that bad either but not designed to hip load

[slparker]

Nah just a 77 set, heavy enoug. Not a fan of the Alice pack, personally. Like all army packs the weight is in the shoulders and lumbar region, not the hips. Consequence of carrying webbing, I guess.

Aarn harness ventilates well.
