This is Made from sustainable upcycled coffee grounds infused fabric, O5-T is stain & odor-free, takes on any occasion. And this is a fresh crowdfunding thing on the Kickstarter website. 

We commute, we attend meetings, we workout, we sweat, and we get spilled by coffee. On a typical day, we encounter all kinds of scenarios that oftentimes are out of our control. If only there’s an all-purpose t-shirt that can do it all.


That is, however, not a reality. At least not yet. Here are a few problems we have with conventional t-shirts.


● Gym shirts are not exactly office-friendly


● Shirts would start to smell once they get sweaty


● Stains are hard to remove


● Clothes always take up the majority of your luggage space when traveling


● Color fades and fabric pills very easily 

We decided to put matters into our own hands and developed the all-purpose O5-T to put these issues to rest. Featuring dual blend fabric covering the ins-and-outs of the t-shirt, and combining advanced sustainable material and cotton-like texture, O5-T allows you to feel free no matter the occasion.

O5-T is designed with all these requirements in mind. The inner layer offers the performance of active wear, providing quick moisture wicking and odor repelling features thanks to the coffee grounds infused yarn.

The outer layer retains the soft cotton-like texture while still offering stain resistance based on the patented technology of dri-release. From formal settings to outdoor adventures, O5-T can do it all.

Unlike your average activewear that screams “I’m going to the gym” with excessive use of mesh and reflective material, O5-T blends fleece to give the fabric a cotton-like texture, giving you a more subtle look.

The dri-release patented technology essentially blends a combination of hydrophobic (water repellent) and hydrophilic (water-absorbing) fibers together, providing 400% faster-drying speed compared to cotton, 100% faster than polyester.

And because this technology is not a surface coating. Instead, it's woven into each thread of the yarn; it has a permanent effect and will not be washed out over time.

O5-T is thoroughly coated with a layer of nano-coating using the latest rotary screen printing technique. It allows an even more close-knit connection with the fabric, that simply lasts longer.

Unlike waterproof coating or waterproof spray that loses its effectiveness after a few washings, O5-T retains its performance even after intensive use. 

We put coffee grounds into extreme high pressure and low-temperature conditions to make it into S.Cafe® nano coffee pellets. These pellets are then melted and infused into the yarn, increasing the surface area thanks to the coffee ground’s physical characteristics. The end result is a natural, toxin-free, and durable fabric.

Coffee grounds are collected from local coffee shops and plastic bottles are sourced from local recycling centers. These “waste” are upcycled and made into something of much higher value.Every t-shirt made means one cup worth of coffee ground and 5 plastic bottles reused. We make sure that we’re making the minimum impact on our environment.

The production process of the O5-T conforms to bluesign® and GRS standards, making them far more sustainable and energy-efficient to produce when compared to other vendors.

Conventional odor repelling fabrics rely on secondary processing of dipping in chemical mixtures. The chemical compound that adheres to the surface of the fiber would be washed away fairly easily and causing harmful impacts to the environment, and in some cases, allergy to the skin.

O5-T achieves its odor-free through the physical characteristics of S.Cafe® yarn. Taking advantage of the countless tiny pores on the surface, O5-T can trap the odor particles and eliminated them. What's more, its effect is permanent. Just rinse it with water and it's ready to rock and roll again.

The surface area of 100 grams of S.Cafe® pellets is equivalent to the size of a football field. The bigger the surface area, the faster moisture evaporates. It only takes a few seconds for the sweat to pass through the fabric, allowing heat to be transferred, giving you this cool and breezing sensation.

Through the quick-drying effect of the S.Cafe® yarn, and the performance of the dri-release fabric, you get the best of both worlds - A moisture-wicking performance beast.

The majority of sun protection fabrics rely on the post-processing of dyeing in chemical mixtures. Because of the coffee ground's porous nature, the uneven surface of S.Cafe® yarn can easily scatter the UVA/UVB light. 

Less is a lot more than you think. O5-T offers you a reality that requires no more frequent laundry, prevents unnecessary buying, and allows you to pack smart and travel light. It’s a go-to everyday wear that happens to be quite environmentally sustainable.

● Odor Free: Remove odors and never decline in performance.

● Stain Repellent: With a layer of nano-coating, anything splashed won't stay anymore. Just simply rinse off with water if you get a stain.

● Quick Drying: Dries 40% faster than regular clothing after you dunk it in water.

● Moisture Wicking: Wick away sweats from the skin fast and keep dry in only 0.4 sec.

● Super Comfy: Breathable cotton-like shirt you can wear all day long.

● UPF 50+ Sun Protection: Sunlight got nothing on you.

● Abrasion Resistance: O5-T is excellent in its abrasion resistance. It's up to level 4 out of 5 based on the ASTM D3512-2010 Standard.

● Last Forever: Retains its performance even after intensive use.

● Eco-friendly: Produced according to bluesign® standards for sustainable materials and production.

● Easy Care: Stay fresh longer and less laundry in general. 

If you had to pick just one item from the closet, O5-T should be on the top ones of your list. It’s your dating shirt, your camping shirt, your favorite shirt that can be worn for days, it is all you need to pack on a weekend trip or the outdoor adventures. 


If a piece of garment can last, then there’s one less reason to buy new clothes. O5-T has gone through rigorous testing to ensure its durability. We believe that with O5-T, there won’t be a need to buy more clothing in the foreseeable future.

Every run of machine washing takes around 8 gallons of water. With O5-T, you’ll be able to save water and limit the amount of time you have to spend visiting the laundry store.
You can’t go wrong with the basic T-shirt. Classic crew neck design and unique asymmetric hem flatter your shape and form. Reinforced inner stitching makes it tougher and more durable.

Unbutton the shirt to show off a little bit of your achievement at the gym. The Henley shirt design features a slightly narrow and symmetric hem for extra comfort. The stitchings are hidden beneath to give it a seamless look. 

Garments may vary due to design and manufacturing differences, so the measurement difference between your t-shirt and O5-T may be ±1 inch (±2cm). If you’re on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If your measurements for chest and waist correspond to two different suggested sizes, order the size indicated by your chest measurement.

Using the same dual blend fabric, you can expect the same amazing performance from its t-shirt counterparts. Our testings have shown that the towel is capable of absorbing 100ml of water within seconds.

Design And Prototype 

The creation of O5-T stems from our desire to pursue perfection. We wanted a piece of clothing that can be worn on any occasion, any moment on the same day. We began to conduct surveys to get the real opinions from the crowd. 

We want to deliver a product that checks all the boxes in every aspect. All our products are made in Taiwan, and we’ve joined hands with sustainable factories here.

 After several prototyping and the thorough testing, we are now ready for mass production. Hopefully our O5-T can deliver a whole new T-Shirt experience for all of you backers.
