Sizing and Fitting of your Osprey Pack

Fit is the key to pack performance. Take the time to get it right. Most Osprey packs are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine (as shown in the picture below) from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck).  Use the table below to determine your pack size.

Great pack but you have to break it in

Right out of the box this pack has great adjustability but it is stiff around the hip belt. I've hiked about 50 km with it now and the hip belt stiffness is all but gone. That was in the heat of a Queensland summer. Cooler climates may take longer for this to happen. I've been caught in a couple of summer thunder storms whilst far from home and can say that the rain cover really works. The good thing is that it is attached to the pack and lives in its own pocket so there's no leaving it at home. The harness is easily adjusted by one person but you do have to take the pack off to do this. I was measured for torso size and opted for the small. A medium technically would have done but by the time the shoulder harness was adjusted right down the load lifter straps were at too high an angle to be effective. So my advice is to get measured and get the correct size pack and harness. The hip belts come in a number of lengths and I found the small size hip belt didn't wrap around my waist far enough. I had the hip belt swapped out for a medium size at no extra charge. So far I've been averaging about 12kg of all up weight and this feels comfortable. The hip belt has pockets and the good thing is that they stay put as you tighten the hip belt I.e. they are always easy to open. The straps on the hip belt are looped so you draw them forward to tighten the belt. This gives much more compression to the belt than with systems that have you pulling the straps across your body. The stow on the go system for your trekking poles was new to me and took some getting used to. I have slightly modified the bungee cordage so that I don't have to collapse the poles to use this feature. This is really handy for temporarily tucking the poles out of the way while you do something else. The lid on this pack does come off but doesn't convert into a day pack. You can buy a strap and connect it to the lid so you can wear it like a satchel. This is great for taking your swimmers and a towel to the swimming hole and leaving the big pack at camp. There is a pouch inside the pack for a hydration bladder and a hook to hang it off. Be warned, once your gear is in the pack it is damned near impossible to get the bladder in. So fill it up and install it first. There are heaps more features to this pack and I haven't used them all yet. I am VERY happy with this pack and am also impressed with the service from Seven Horizons.

Osprey Aether 70

Really happy with pack. Fits perfectly. However was not aware the Aus version was different to the US & had no day pack Included as the built in lid.

A great deal for kit and kaboodle.

Quality of the bags is great.
Finally got around to a load test and seems ok.
As one of those people that could go either way with sizes. 185cm. 75kg.
Im a little unsure how I feel on the size. But If i hadve gone larger Id still be wondering.
Included a hand written thanks from Tim which was a nice touch.

Osprey Aether - Perfect for our multi day hike on Hinchinbrook Island

Hinchinbrook Island in FNQ is Australia's largest Island National Park, you have to be completely self sufficient on the Thorsborne track.
Jamie used the Osprey Aether 70L and I took along my Osprey Ariel 50L.
We had enough room in our packs for 3-4 days worth of food, a camp stove, air mattresses, change of clothes, towel, cooking equipment and gear, tent etc. These Osprey packs were the perfect fit for this hike which involved lots of rock hopping, creek crossings ascending and descending tracks.
The packs did not let us down. Osprey is a great brand, they really design their gear well!
