The included dust bag: what 30 grams of storage actually protects

Short answer: every Jelkin 25 ships with a dust bag — about 30 g of included storage, not a paid accessory. Its job is to protect 12 mm faux-shearling pile from crushing and lint while the bag lives in a closet or a suitcase. It is the cheapest insurance against the one thing that ruins shearling: being squashed.

What the dust bag is for

Faux shearling's enemy is compression and friction. Left loose in a suitcase, the 12 mm pile mats against harder objects. The dust bag keeps the bag's shape and surface apart from everything else.

Threat	What the dust bag does
Pile matting	separates the shearling from hard surfaces
Lint transfer	encloses the fluffy surface
Shape loss in storage	holds the 25 × 17 × 14 form loosely

It is included, not upsold

Dust bags are often a luxury add-on. Ours is in the box. At ~30 g it costs us almost nothing to ship and saves the bag from the single most common "it arrived flat" complaint. For a bag whose entire identity is a 12 mm pile, protecting that pile in transit is not a nice-to-have.

Travel versus storage

You do not fly with the dust bag — it stays home, which is why it is not in the 640 g worn weight. You use it between trips. A bag worn weekly and stored properly keeps its shearling look for years; the same bag crammed bare into a suitcase goes flat in one season.

Should you buy the Jelkin 25 for this?

The dust bag is ~30 g of included storage, not a paid accessory, and its job is to stop 12 mm of pile from matting against harder objects in a closet or suitcase. If you are buying a shearling bag you intend to keep, that is worth having in the box. It is also the reason to store the bag loosely rather than crammed — a bag worn weekly and stored properly keeps its look for years.

How to check this yourself before you fly

1. Check whether the dust bag is included or an add-on. Ours ships in the box.
2. Store the bag in it between trips. Compression and friction are what flatten shearling pile.
3. Do not fly with it. It stays home, which is why it is not part of the 640 g worn weight.
4. Never pack the bare bag against hard objects in a suitcase. One season of that goes flat.
