Materials & Care


900D Polyester Fabric


Light in weight | Tough | Water-repellent

We use 900D high density polyester as urban collection's outer shell. The fabric itself is water-repellent coated. The special coating allows your bag to stay water resistant by delaying water absorption through the fabric.

Note: ‘water resistant’ is not ‘100% waterproof’.

Also, the high density fabric features its durability and keeps the bag in a good shape all the time. In a completely new condition, the bag might be a little bit stiff. It will get softer and more comfortable after few uses!

420D Crinkle Nylon


Extra lightweight | Sturdy | Impermeable

Nylon itself is water-resistant, so if water or any other liquid falls onto it, you can expect it quickly roll off the surface and dry quickly. This property makes nylon the perfect fabric for outdoor packs. This crinkle nylon also features its flexibility in bending, minimal weight and very durable nature.

Note: ‘water resistant’ is not ‘100% waterproof’.

To keep your bag clean and fresh all the time,

  1. We suggest you to wipe the bag with cool water, then air dry it after every use.
  2. Mild soapy water and soft-bristled brush can be applied for stubborn stains.
  3. Washing machine, detergents and solvents are not recommended as they can damage the protective coatings on the fabric.
  4. There is a reusable non-woven bag included in each pack item It is for you to keep the bag away from dust and direct sunlight if you’re not going to use it in a short period of time.
waterproof nylon zip


Waterproof | Smooth | Matte finish

This nylon zip is coated with Thermoplastic Polyurethane (TPU) which prevents water or other liquid from penetrating under normal use. Unlike the traditional way, we install the zipper 'inside out', so as to maximise the result of protection. The matte finish also gives a sleek and smooth appearance.



brushed fleece


Warm | Cosy | Mid-weight

You can find our hoodies incredibly soft and comfortable for all-day wearing. It is because our mid-weight fleece (27% Cotton, 70% Polyester, 3% Viscode) has gone through a brushing process during production. Back of the fabric is brushed to loosen the fibres and create a nap which offers a warm and plush feel. 

Washing Instructions: Machine wash cold, inside out, with like colors. Do not bleach. Do not tumble dry. Do not iron directly on design.

combed ring spun cotton


Soft | Refined | Comfortable

Ring spun cotton is made of smoother and longer yarn, compared with regular cotton. The term “ring spun” means that the yarn goes through a special spinning process that’s designed to thoroughly soften and straighten each fibre. It has a result of softer, more refined fibres.

COMBED AND RING SPUN COTTON, the kind that AmSTRONG is using, is much softer. After the spinning process, the cotton fibres are combed through to remove impurities and short fibres while ensuring it stays soft to the touch.

Fewer impurities mean a smoother (less stiff and scratchy) surface which offers you maximum comfort!
