Converting to Daypack

  1. Lay the shoulder straps flat so you can have the chest strap right way up. The beige colour webs should be at the top.
  2. Clip the balance pockets together using the side buckles.
  3. Clip the adjustable spring clips to the matching beige 20mm web loops at
  4. the top of the pockets. Clip the hooks to the matching grey 15mm web loops at the top of the pockets.
  5. Put the pack on and adjust the settings of the top and bottom webs in their respective buckles so that the chest strap sits at a comfortable height across your chest.

I found none of the usual sore spots (shoulders, hips, upper back) when I loaded the Liquid Agility with 35 pounds for a 20-mile day, as compared to virtually any other traditional internal frame pack. I'm rather convinced that decoupling shoulder and hip belt movement from the load bearing suspension components has a significant impact on muscle fatigue when carrying weight for long days. The front pocket system, which is integrated with the suspension, greatly improves the maximum load carrying capacity of the Liquid Agility pack. It carries a 30 lb (14 kg) load in outstanding comfort relative to most 30 L-range internal frame packs on the market.

Ryan Jordan. review.

I am extraordinarily pleased with my Aarn Liquid Agility pack. I recently took a 6 mile / 5 hour hike that had an average slope of approximately 25 percent and a maximum slope of 60 plus percent. I was carrying roughly 17 pounds in the pack. At the completion of the hike when I removed the pack, I had no sore spots and no aches in the back or shoulders. During the steepest portions of the climb I was using my hands pretty much continuously. There was no binding or pulling from the pack on either my shoulders or arms.

I used the optional Balance Pockets on this hike. The convenience offered by being able to access my stuff (glasses, GPS, maps, snacks, etc.) without removing my pack was a huge plus. I took advantage of the internal pocket and zip opening for a hydration pack, carrying 3 liters of water with electrolytes with me. It was nice to have my fluids so easily available.

In summary, with the pack and Balance Pockets I was able to walk upright with an easy movement. I had uninhibited freedom to use my hands and arms. I arrived home unstressed from carrying the pack. As a bit of frosting on the cake, getting off and on with the pack was easier than with either my day pack or bike pack. The Balance Pockets on the front make on and off of the loaded pack a bit like putting on a coat.

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

I do not have the coordination anymore to master this simple sequence

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

My 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.

Having the right equipment can make the difference between an awesome time and a rough one. Let's do it right.

Not a recommendation.
Get outside.

Some of the best things in life happen outside; the pre-dawn ascent, the post run coffee, the all day ride, the late afternoon dive and drinks around a fire to close out the day. We try to spend as much or our time doing these things with the people we love and think you should too.

the right gear

We work to have the right tool for the job which lets you shop less and get outside more. That is what Peak Outdoors is about.

Paddling Sebago? Check.

Skiing Tucks? Check.

Riding Huts and Trails? Check.

You get the idea.
