Baggu is a San Francisco brand founded in 2007 around one idea: the standard reusable ripstop-nylon shopper, done in good colours and prints, folding into its own pouch. It grew into shorthand for the whole fold-up bag category — people say 'a baggu' the way they say 'a biro'.

Why did foldable bags become a fashion thing?

Plastic-bag charges and bans made carrying a reusable rational; Baggu and its peers made it aesthetic. Once the fold-up bag was something you chose in a print you loved, it crossed from kitchen drawer to outfit — and 'packable' became a quality fashion talks about.

What folds flat besides nylon?

String nets have folded to pocket size for a century, and knitted metal mesh does the same trick with more presence: no creases, no memory of the suitcase, and it springs back to shape. Nylon is lightest; mesh is the version that reads as jewellery when unfolded.

baggu, and the foldable bag

Some brands own a product; a few own a word. Baggu — the San Francisco label founded in 2007 around a fold-up ripstop shopper in good prints — owns "baggu" the way Hoover owns vacuuming. Its real achievement is bigger than the bag: it made foldability a fashion quality.

The trick Baggu pulled

The fold-up shopper existed for decades as a kitchen-drawer object. Baggu's move was treating it as a design surface — seasonal prints, collabs, colours worth choosing — so that the rational purchase (plastic-bag charges were arriving) became an aesthetic one. The reusable crossed into the outfit, and "packable" entered fashion vocabulary.

The foldable family tree

Baggu's nylon has ancestors and cousins. The string net folded to pocket size a century earlier — the original just-in-case bag — and the knitted metal mesh is the family's premium branch: it crushes flat with no creases and no memory, then unfolds into something that reads as jewellery rather than kit. Nylon wins on grams; mesh wins on presence and lifespan.

Choosing your foldable

Nylon (the Baggu lane): lightest, cheapest, printed — the errand workhorse.
String net: nearly as light, charming, but frays and mildews with the years.
Knitted metal mesh: the buy-once version — fold-flat convenience in a material that contains no plastic and outlives the other two combined.

Ours folds too

Tonsiba (£95) packs to the size of a rolled t-shirt and shakes back into shape — the foldable that also carries the evening. Hand-knitted brass, made to order, dispatched within 14 days.
