Topo Designs · Block Bag 3.5L

Notebook at the back, change at the front: a small square bag that holds its shape.

At the market, you grab your change one-handed from the Block Bag, a small square crossbody bag, in one of the zipped pockets on the front, your phone in the other, and the bag stays put against your hip. At the back, the main compartment lined in yellow takes a notebook or a paperback, your keys hanging from their clip: 3.5 litres of recycled nylon ripstop that hold their shape. The notebook and the phone, not the jumper.

Small things at the front, the notebook at the back.

To scale

A little wider than an A4 sheet, a little taller than a phone standing upright.

19.1 cm tall, 26.7 cm wide, 6.3 cm deep: a small square that holds its shape.

What fits inside

3,5L

3.5 litres, well organised: the notebook at the back, small things at the front.

The main compartment, lined in yellow, takes a notebook or a paperback; inside it, a zipped pocket and a key clip. On the front, two zipped pockets with mesh pockets keep small things apart from the rest.

  • A notebook, in the main compartment
  • Your keys, on their clip inside
  • Your wallet, in one of the front pockets

Inside and out

The Block Bag packed before your eyes: the main compartment, then the front pockets.

Topo Designs

A sewing machine in a Fort Collins basement, in 2008.

Since 2008

Jedd Rose buys a sewing machine and sews the first bags in his basement in Fort Collins, Colorado; Mark Hansen asks around for people who can make them.

Tough and simple

The two founders wanted gear like the kit they grew up with: tough, practical, classic, the opposite of throwaway and overcomplicated. The same bag goes from the city to the trail.

Guaranteed, repaired

Topo Designs guarantees its bags against defects in materials and workmanship for a reasonable lifetime, excluding normal wear, accidents and lack of care, and would rather repair than replace. For a bag bought from Eiken, the claim goes through us.

Eiken's take

Why we chose it
Two zipped pockets on the front, a key clip and a shape that holds: a small crossbody bag where everything has its place.
Worth knowing
6.3 cm deep: the notebook, your wallet and keys, not a water bottle or a jumper.
Who it's for
From the morning commute to days on the road, for anyone who likes to know where everything is. For a soft bag that folds away at the bottom of a suitcase, look at the Moonlight instead.

Baptiste, Eiken

Questions

What are the dimensions of the Block Bag?

19.1 × 26.7 × 6.3 cm (height, width, depth), for 3.5 litres.

What fits in the Block Bag?

A notebook or a paperback in the main compartment, your keys on their clip inside, your wallet and small things in the two front pockets.

Is the Block Bag waterproof?

No, it isn't made for rain: in steady rain, water eventually soaks through its recycled nylon fabric. Put your phone in a pouch.

How do you wear it?

On an adjustable strap: across your chest with the bag on your hip, or simply over one shoulder.

Block Bag or Moonlight Crossbody Bag?

The Block Bag, 3.5 litres, is a small square bag that holds its shape, with two zipped pockets on the front. The Moonlight, 4 litres and 160 g, is a soft crescent in PFC-free water-repellent ripstop.
