Aarn USA recommends either the Sport or Expedition Pivoting Balance Pockets to accompany this comfortable backpack. The Effortless Rhythm can be unclipped at the top and pivot each side under your arms to maintain balance in many situations. Pivoting Pockets may need a hipbelt length adjustment to get the best gap to feet visibility (only required once).

" I broke my back some years ago (T7 and T8) and have problems now carrying weight for any length of time. I get a real pain like a knife stabbing me between the shoulder blades. But, not when using your Bodypack design!"

Julian Daly, Nelson NZ

“Absolutely the most comfortable pack for my shoulders and neck that I have ever had in 25 years of tramping.”

Meg Kilvington, Christchurch, NZ

"Effortless Rhythm with its two frames could have been designed for me personally. Many years ago I had a small accident involving a bomb as a result I have less muscle mass on one side of my back than on the other. Being able to customise the frames separately means it is the first pack that really fits like a glove."

Hamish Alkman, Limoges, France

“I had no aches or pains in shoulders or hips despite unfamiliarity with carrying a heavy load. The pack moved with me and didn’t prevent or hinder natural body movement. The precision shaping of the hipbelt made it so comfortable. The Balance Pockets worked well to balance the weight distribution. A very impressive performance, certainly the best pack I have used. I am selling my highly-rated NZ backpack so I can purchase an Aarn Bodypack.”

Paul Moreham, Christchurch, NZ

“I used Effortless Rhythm on the Copeland Pass crossing. This is really quite amazing. I was able to walk with it for 3 days and remove it at the end without a single sore spot or any indication that I’d been wearing a pack at all."

Julian Maclaren, Christchurch, NZ.

" For the past 7 years I've worked as a guide and national park ranger on the Overland Track in Tasmania. I walk literally thousands of kilometers carrying heavy packs every year as part of my jobs and have used and have trialed a wide range of different pack makes and models. I've just returned from an eight-day ranger shift trialing Effortless Rhythm with Balance Pockets and Pacerpoles. Both the pack and poles have far, far surpassed my expectations. I was carrying around 30kg for the first couple of the days and was truly impressed by the comfort and freedom of movement allowed by the pack - the Effortless Rhythm is aptly named! The Balance Pockets are an excellent innovation, of which I was skeptical to begin with. Initially I found the pack slightly awkward to put on with these full, but soon got used to it and found the benefits far outweighed any slight inconvenience. Having the weight central to the body meant the pack felt like it was part of your body, walking as if I wasn't carrying any weight at all, and were great for balance. The Pockets also meant that I could have all my essentials and equipment close at hand and could do so much more on the move. With the weight in the pack neutral to the body even with large weights I found I conserved so much more energy and there was much less strain on my body. I have not tried found or used any other pack that could match this. The design of the poles was similarly impressive. Walking using poles with hands in a neutral position is excellent. My hands stayed comfortable after using the poles all week and they were far more energy efficient than other poles I have used.

From the first day all I could do was rave and I have had many people over the week, both guides and other walkers, express interest in both the pack and poles. I can't recommend this equipment highly enough and it would be a privilege to trial and recommend you equipment to clients and other walkers."

Nick Tyson, Cradle Mountain National Park, Tasmania

" I initially purchased the Sport Balance Pockets, but once I had seen the attention to detail and quality build I was convinced to put aside my 'leading name brand' pack and move to an Aarn Bodypack. I purchased the Effortless Rhythm to complete the system. The first impression was that this system is designed by people who had spent a lot of time thinking about carrying loads. The pack is a clean highly functional design with everything knitting together to make a complete highly efficient system. All other packs you may haul on your back, but this one you wear like a coat it is so comfortable. This system is the only one that I have found that truly allows you to get a 'perfect fit'. When wearing the body pack I was outright amazed to have no pain in the shoulders, back, or hips even after hours of hard tramping. Couple this with a huge increase in walking efficiency and the advantages of this system really come into their own. I have been tramping for over 30 years, carrying loads around 35 - 40kgs at times. I have been involved in Search and Rescue and have tried a wide range of different gear. Nothing at all that I have seen, tried, or owned previously comes anywhere close to the quality, design, and outstanding common sense system that Aarn delivers."

George Turner. Nelson, New Zealand

Auyuittuq Pass Expedition, Baffin Island

" Despite all my efforts to minimize pack weight, my pack was over 30 kg. You can’t say it was pleasant to carry; initially all our sacs were far too heavy to lift onto our backs alone, so we always stopped by rocks where we could sit and slide out of our sacs. I became more and more converted by my low-loader, front Balance Pockets and all (nicknamed ‘Boobs’). Canadians are so traditional …… I endured endless grief about my odd sac, but occasionally with the sun to the side I would glance at our shadows and sure enough there was a bunch of hikers hunched forward under their loads except for one short guy who seemed to be standing upright... Smugly I remembered my 20% energy saved! When I first tried the Effortless Rhythm I was not sure how much difference it would make, but swapping back to a traditional sac (I carried a few peoples’ sacs across a few rivers) it was instantly obvious that the Aarn’s claim about posture was correct. In addition, the load was kept very low and compact — great for crossing moraine and rivers and definitely the most stable sac on the trip."

Tom Sibbald, Windermere, UK

Troubleshooting

PROBLEM

CAUSES

SOLUTIONS

Sore Shoulders

Pull back force on shoulders from weight behind

Add Balance Pockets, or if using them, put more weight in them and loosen front shoulder strap webs

Too much weight on shoulders

Loosen front shoulder strap webs

Hipbelt has slipped down

Raise hipbelt & retighten &/or shorten

Balance Pockets are pulling down on bottom of shoulder pads

Increase back length: Pull up on navy top back panel web

Bodypack is too hard to put on

Incorrect technique used

1. Loosen hipbelt webs before putting the bodypack on for the first time.

2. Follow this sequence: Place hands underneath Balance Pockets; grab hold of hipbelt center buckles, lift both Pockets & hipbelt up to the right height; clip center buckle together & tighten the tension web loop at top and bottom to get an even pressure at the top and bottom of the hipbelt

3. When taking the pack off, before releasing the hipbelt center buckle, loosen the side buckles. With familiarity, you can release the 2 tensionlock buckles on each side with each hand simultaneously, by pulling the buckle ends up. Now you have set the pack up to be easy and quick to put on next time

You’re having issues with making adjustments

Substitute Universal Balance Bags for Balance Pockets. These quickly and easily attach after you have put the pack on

Pack leans to one side

Your pack will lean to one side, like any brand of pack, if you have the shoulder straps and/or hipbelt adjusted unequally on both sides, or you have loaded the pack unevenly.

First check that the top stabilizer straps are equal length and the front shoulder strap webs are also equal length. Now check that the hipbelt parts are adjusted to equal length and angle on both sides of the center base plate and the side tension adjustors (cord or web) are of equal length both sides. Now with all these adjustments made, check that the hipbelt ends are sitting at a similar position on each side of your pelvis with the pack on. Finally, check that your U-Flow movement (the movement when you lift one shoulder), is equal on both sides. With everything centered, including the load, there should be no reason for your pack to lean to one side.
