Choosing between POSH and jute

Most first-time shibari rope buyers face one decision before any other: natural rope or synthetic. At our shop the choice is POSH (synthetic) or Ogawa jute (natural). Both are 8 m, both cost €20 a rope, both work for the same set of ties.

This entry is the long version. The short version: jute is the fibre modern kinbaku standardised on and rewards a small amount of care; POSH is the low-maintenance practice rope you can throw in a drawer, and forgives a lot.

What POSH actually is

POSH is a synthetic rope engineered to behave like a natural fibre. It is not nylon, not MFP, not cotton, and it is not trying to be shiny. It has a matte surface, a slight fuzz, and enough tooth that a friction holds.

POSH comes in a wide range of colours. We stock natural, beige, brown, red, purple and dark blue. Our jute comes in one colour: jute. If you want another colour, choose POSH or dye the jute yourself.

The two-line mental model

The choice is like choosing a kitchen knife. Jute is the Japanese carbon-steel knife: it rewards care with feel and beauty, but it needs maintaining. POSH is the stainless-steel workhorse: it handles rough use, washes clean and asks little afterwards. Both do the same job. Pick the upkeep you would rather do.

Both cut. The choice is what you enjoy maintaining.

When jute wins

Feel. Jute is the fibre modern kinbaku standardised on from the 1980s. The older Japanese tradition is hemp, covered in jute vs hemp. Synthetic can approximate the feel of jute; it does not replace it.

Friction. The dry, slightly fuzzy surface of jute engages cleanly with other jute, which is what a friction hitch relies on.

Heat under movement. POSH is polyester and builds heat faster than jute when it moves quickly across skin. That makes friction burns easier to cause.

Aesthetics. Jute looks like the rope in the photographs and demonstrations you have been studying. Our brown and beige POSH get close, and whether close is close enough is a judgement only you can make.

Smell. Jute carries the dry, earthy smell of natural fibre and, when new, a faint batching-oil scent. Some people consider that part of its appeal. POSH has little smell of its own.

Care as a practice. Hanging the rope after each session, oiling it every couple of months, the slow softening over months of use. Some people enjoy that and some resent it. Only you know which.

When POSH wins

Water and sweat. POSH washes. You can take it through a humid practice session, use it in nature, wash it in a pillowcase on a cool delicate cycle, hang it to dry, and pull it out ready to use. You will not need to do it often: once or twice a year is normal. Natural rope does not tolerate that treatment well; frequent soaking and machine-washing shortens its life.

Practice volume. Synthetic forgives the rapid, repetitive tie-untie-retie loop that beginner practice involves.

Published strength figure. POSH ships with a manufacturer-published breaking-force figure. A breaking-force number is not a working load either way; suspension work applies a safety factor on top of it. We publish no equivalent figure for our jute because testing one natural-fibre sample cannot guarantee the strength of another.

Travel. Synthetic is harder to damage in transit. A piece of POSH at the bottom of a packed rope bag does not need the same airing-out as jute.

Recovery from neglect. Both fibres last well with reasonable care, but POSH tolerates inattention better than jute. A POSH rope picked up after a long pause is generally still workable. A jute rope after the same pause may have stiffened and set into its stored shape, and wants inspecting and conditioning before it goes back into use.

What POSH does not forgive

Everything above is POSH being tolerant, so here is the one thing it is not tolerant of: heat.

Do not store it near a radiator. Do not tumble dry it, even on low. And do not run it fast across a hard surface that will heat it, because a rapid pull against a metal carabiner can do exactly that. What you get is a glazed or fused patch, and unlike almost everything else on this page, that does not reverse.

Jute has no equivalent single weakness. It has a slower, more general one: it dries out, fuzzes, thins, and eventually stops being a rope you would suspend with. Which brings us to how each fibre ends.

They fail differently, which matters more than how long they last

Neither fibre has a lifespan you can put a number on, and anyone who gives you one is guessing. What they have is different failure modes, and knowing which to watch for is the actual skill.

Jute gets retired due to hairiness made of broken fibre, thinning against its own unworked sections, one strand riding proud of the other two, and a brittleness that oiling does not fix.

POSH gets retired due to kinks that do not come out with gentle flexing, glazed or fused patches, and cut strands.

Both get retired on inspection. Rope care covers what to look for and when a rope stops being a suspension rope.

Breaking in

Jute and POSH both soften with use, but POSH has a shorter and simpler break-in.

New jute is stiff, because of the twist and the batching finish. Ours is cleaned and hand-finished before it ships so it arrives ready to tie with, and it keeps softening over the first weeks you use it. Breaking in new jute covers what changes.

POSH also arrives ready to tie with, but it can feel firm at first. Regular use loosens it without oil or wax. When it no longer holds itself stiff and bends under its own weight, it is broken in.

Why we sell them at the same price

Several EU rope shops price synthetic below natural and treat POSH as the budget option. We do not.

We charge €20 for either rope at 8 m because the choice should be about what you enjoy maintaining, not about your budget. Some students prefer natural fibre. Some prefer synthetic. Both are honest first ropes. Pricing one above the other turns a feel-and-care decision into a budget decision, and that is not the decision we want our students to be making.

Diameter, briefly

We sell POSH at 5 mm and jute at 6 mm. In our handling the two feel close enough to work as parallel options. That is how we chose to stock our own two ropes, not a rule about synthetic and natural rope in general. Other EU shops sell POSH at 6 mm too; that is also fine. Full discussion in rope thickness.

What about JBO

Standard Japanese jute, including the Ogawa rope we import, is processed with petroleum-derived jute batching oil (JBO) before yarn manufacture. The oil softens the raw fibre and gives the spun yarn its cohesion. Our jute is hand-finished in Leuven. You may notice a faint scent when the rope warms up in use. It fades.

Some buyers prefer rope batched with non-mineral-oil alternatives. Two German suppliers worth knowing about are AMATSUNAWA, whose material on soybean batching is the EU reference, and KOUMANAWA, who also sell JBO-free jute and publish good conditioning documentation. Both ship to the Benelux. In the meantime, our jute is petroleum-batched and Belgian-finished. Full chemistry in JBO and batching oils.

What about hemp

Hemp is a separate natural-fibre option we do not stock. Full comparison in jute vs hemp.

Recommendation, for a first rope

If you have no preference, the question to answer is which knife you enjoy maintaining. If oiling and hanging a rope sounds like part of the practice, buy jute. If it sounds like a chore, buy POSH. They cost the same here and they tie the same ties.

If you are at a class with an instructor, ask them. Their answer is informed by what you specifically are likely to do with rope.

What we actually do

Ogawa jute and POSH, both cleaned and hand-finished in Leuven, hand-packed and usually dispatched within two working days.

EMT shears are bundled free with every kit and sold standalone for €8. The starter kit (three 8 m ropes plus shears) covers everything an introduction class will ask for.
