The back panel of the Ski Touring pack

The back panel is probably the most interesting part of that pack. Since it is an ultralight children’s pack, I added a shoulder strap’s height adjustment option to let the pack grow with the owner.

The back panel also contains a padding sleeve with a hook and loop tape closure to be able to add a foam pad and some more structure is required.

The daisy chains will be taking some serious load when the pack is full and skis are hanging on its sides. So the daisy chains will need to hold under strain. The achieve that, the pack’s fabric is carefully strengthened along the daisy chain. In the following pictures, the daisy chain is blending with a folded seam. It also is the point where the padding sleeve is sewn into the back panel, which backs the fabric without any specific weight penalty. Nonetheless, the seam is sealed and hidden with a strip of VX21 RC, which also adds strength to the bartacks, totaling the layers of fabrics to 3 behind the webbing.

The rest of the back panel is relatively simple. Thee is a thin layer of closed-cell foam and 3D mesh on the lower part, decorated with a mountain-top pattern.

The shoulder straps lower attachment is a standard load-bearing triangle and webbing designed to use with a nylon ladder-lock buckle. A lightweight hip belt is also important, since the pack loaded with skis would have an unusually low center of gravity. I added a removable gear loop on the hip belt

There you have it! These were the most important details of the pack’s back panel.

Since you read it until the end, here are a couple of bonus pictures that did not make the cut.

Have a great day!

The Ski Touring Pack

When a friend asked me to design a pack for his young son, I knew I had to give it a try. Little did I know that I would be designing an ultralight Ski Touring pack for a young outdoor aficionado! I mean, what a responsibility!

I wanted to experiment with the ski attachment options and figured I could design the side compression straps with the option to run them across the pack. My original intent was to either hang one ski on each side of the pack attached with the compression straps in a standard configuration or secure the pair to the front of the pack with one side of the compression straps reaching to the other side. Eventually, the choice would befell the future owner of the pack.

Apart from this little experiment, we designed the rest of the pack together, and settled on two front daisy chains and a relatively big zipper pocket. There are also some low-profile side pockets on each side for commodity, but since the main idea is to carry skis on the sides, the pockets are not a main feature. I just find that the weight penalty is small enough to warrant the extra functionality when you need it. Here are some more photos of the complete pack body.

The idea for the shoulder straps was to make a set of test straps first and try the fit, since I was not very confident fitting straps to a child on the first try. Since children grow fast, I wanted the pack to grow with him. Otherwise the pack won’t be useful for very long.

In order to keep this simple and as lightweight as I could, I thought the shoulder straps could attach to a daisy chain instead of being permanently sewed onto the back panel. That way I can add additional daisy chains to allow for higher attachment points and I can make new straps when these ones get too small.

The weight penalty of the adjustable height shoulder straps is not negligible in this weight category, but can be later reduced when adjustment are no longer necessary. A set of “grown-up” straps can be permanents attached to the higher daisy chain and the attachment hardware and webbing can be completely cut-off then. In this scenario, the horizontal daisy chains would remain.

The shoulder straps themselves are actually quite small. In the pictures, these are test straps, which will eventually get replaced after a couple of trips, and are just a way for me to figure out how the wearer wears the pack. The construction is similar to my usual straps except these do not have an S-shape but rather a J-shape.

I can’t wait to see the pack getting some mileage.
