The backpack straps are not detachable, so they never get lost: they fold into the back pocket. Only the padded shoulder strap comes off.

Side by side

Made to be used, not babied

Next to a typical mass-made ITA bag, here is what the 3-Way Cotton Backpack 15" does differently.

Feature

3-Way Cotton Backpack 15"

Generic mass-made ITA backpack with thin PU straps, for comparison — Flimsy, thin straps

Typical dropshipped bags

Window

Scratch-resistant 0.8 mm TPU window for everyday use

Thin PVC that scuffs and goes cloudy

Structure

Firm foam body that stands up on its own and protects your laptop

Flimsy, slumps when you set it down

Zips and hardware

Heavy-duty YKK-grade zips, metal D-rings and clasps, strong buckles

Light zips and hardware that snag or snap

Fabric

12oz heavyweight cotton

Thin fabric that wears through

Inside

Structured, thick polyester lining

Thin lining that tears

Anti-theft

Anti-theft pocket in the pin window

Zips anyone can open in a crowd

Hook and loop

Strong hook and loop on both pin pads and the laptop strap

Weak hook and loop that lets go

Attachment points

11: 7 D-rings (4 in the window, 1 on the strap, 2 on the sides) and 4 clasp zips

A loop or two, if any

We make small batches, not tens of thousands, so every bag can be built properly.

Pin it once

Build it once, carry it everywhere

Lay your pins out on the pad at home, then slide the whole display into the window in one go. Swap pads, swap looks.

Pin layout shown is illustrative

Made for everyday, made like you

Not just for cons. Shift it between three carry modes and use the window for storage or pins, so it's as loud or as quiet as you are. Two hook and loop pin pads, 24.5 × 28 cm each, swap in one go.

Small things that add up

Up close

Water-resistant zips

Cotton Convertible ITA Bag 15", black: close-up of the anti-theft lobster clasp on the zip pulls

Clasps on the zips

Lobster clasps hook the pin window's zip pulls together, so the window is harder to open in a crowd. Metal D-rings and clasps throughout.

Cotton Convertible ITA Bag 15", black: D-rings inside the clear window holding charms

Seven D-rings for charms

4 in the window, 1 on the strap and 2 on the sides, for keychains, charms and plush.

Cotton that handles a con weekend

12oz heavyweight cotton and heavy-duty hardware. Water-resistant zips help keep rain off your pins and tech; the cotton body is fabric, so it isn't a waterproof bag.

Made to stay clear

Scratch-resistant 0.8 mm TPU stands up to everyday knocks from keys, pins and bumps, so it keeps its clarity without babying. 21 × 23.5 cm visible.

Designed for everyday use. Deliberate scraping on rough surfaces like concrete or brick can still mark it.

Hang charms by the window

Clip keychains and charms onto the lobster clasps around the window.

Rearrange without unpacking

The window zips open on three sides, so you can reach in and move pins and charms around.

Full description

🎒 1 bag -3 modes. Scratch-resistant pin display for everyday use. 2 pin pads . Tear resistant cotton made to last.

Every day is different and now your bag's style and theme can change with it.
This is the 10th collection of our Everyday Ita bag series. 10 years, 40+ campaigns, 10,000+ bags. We know exactly where ITA bags fail because we've been fixing those problems with every generation. The 15" 3-Way Cotton Daily ITA Bag is everything we've learned, built into one bag.

The 15" 3 in 1 ITA Bag v4 switches between three carry modes, the backpack straps tuck away completely and the shoulder strap detaches when you don't need them. No bunching. No creasing. No digging around.

Backpack: EVA foam straps (yoga-mat grade). Breathable, reinforced edging, triple-stitched at every stress point. Comfortable even fully loaded.

Laptop Bag: Tuck the backpack straps away and remove the shoulder strap for a clean, minimal carry. A padded sleeve with a hook and loop strap protects up to 15" devices or A4 documents. Your laptop stays put even when you're moving.

Shoulder bag: Detachable padded strap, adjustable from 98 to 140 cm (38.6 to 55.1 in). An anti-theft pocket inside the pin window keeps your phone, wallet or transit card close.

💡 Minimal mode: Want to lose the pins for a day? Pull out the pin pad and use the front window as a see-through pocket for everyday accessories.

Care: Wipe the window and body with a soft, damp microfibre cloth. Avoid resting the bag window-side down or sliding it against hard or sharp edges, as pressure from pins behind the window can cause scratches.
