Building one panel at a time

There is something to be said about simple designs. In this case, building the Slumber pack as a very simple “brick” shape made the construction of each panel a breeze, and completely independent from one-another, at least until the final assembly.

The Slumber Pack

The ABC Slumber is a 20+ liter pack designed for short overnight hikes, while carrying limited supplies, and maybe a bivy and sleeping bag combo. It’ll fit a deflated sleeping pad (which can be strapped on-top or below the pack), a good 2 liters of water, some warm layer(s) and rain protection. And of course, a small first aid kit, because you should never hike without one!

On this version, the main body is built out of X-Pac LiteSkin LS07. It’s not the most abrasion resistant fabric, but it offers good protection against the elements for a lightweight laminated fabric. For better wear resistance, the pack is reinforced at the most exposed parts with low denier non-coated Cordura. Here are some more specifications:

Specs sheet for my fellow gear junkies

The design relies on using a sleeping bag inside the pack as padding and therefore does not necessarily need a foam pad to protect your back. If you need to protect your back better, I’d recommend using a 10mm high quality closed cell foam (for example Evazote EV50) cut to dimensions.
