I’ve seen many examples of wrapping the cord around zipper pulls to make them silent – but it will be really silent, if wrapped from both sides of puller.
The only restraint – cord must be thin enough to come through the hole three times. So 550 cord is inappropriate.
Poor man’s substitute for quick attach tri-glide buckles and for G-hooks
Driven by the idea to save money and simplify logistics, I made a pair of concepts of dirt-cheap analogues of quick-attach ladderlock buckles.
The task is – to connect two webbing loops (for example, attach/detach compression straps on the backpack)
The solution – cord loops, locked with
2) the strap itself
Backpack shown utilizes the previous concept, expanding zippered bag/ pack entrance – color marking sheme is similiar to linked post.
Traditional contracting rucksak mouth and modern clamshell zippered pack entrance – both have tradeoffs. Pack entrance shown below combines them and therefore inherits their advantages and disadvantages.
Details are somehow explained below but would be much more obvious in prototype.
Some means to join parka and sleeping bag in one already exists and is known as “elefant leg”. But this solution suffer from tightness, as volume of resulting sleeping bag is the same as parka’s. More volume needed, and it is possible with frontal insert, look at the sketch.
Frontal zipper on parka embed the frontal flap on the “tail” from left and right sides (look A and B). And additional bottom zipper on parka connects with its vis-a-vis around the tail (look C). There is a little detail not shown on sketch, a kind of face cover on top of the flap.
What is the idea?
To join two things in one.
What is the difference?
More inner space.
What is the advantage?
Less overall weight of two things.
What are the disadvantages?
Redundant weight of standalone parka.
Moisture trapped in parka.
