My small “carry-always” kit
This is the kind of kit that cuts the most waste with the least effort. Choose your own versions; I’m brand-agnostic. Well – almost. I like Apple, so many of the products I carry daily are Apple-related. Designed in California, manufactured in Asia.
1) Reusable earplugs (and/or noise-cancelling headphones)
Why: Planes, long bus rides, noisy hotel corridors, street musicians at 2 a.m. – whatever it is, noise erodes sleep and focus, and it’s more than an irritation.
How this cuts waste: Stop taking those “freebie” earplugs on planes and buses that you use once and bin. Bring one pair of high-quality silicone or foam earplugs in a tiny case. You’ll keep them for years and sleep better. I also carry over-ear headphones with a plug-in cable – many places still offer wired entertainment, and sometimes I need more noise cancellation than earplugs provide. I also want better sound quality when I record videos or similar content. And yes, I just learned Apple has released a new version of AirPods Pro with excellent noise cancellation, which might replace my 6-year-old pair.
Pro tip: Noise-cancelling lets you keep volumes lower, protecting hearing over the long term.
My rule: I never accept the airline earplug kit. I carry my own. It’s not a moral performance – it’s simply better.
2) Refillable water bottle
Why: Bottled water has a heavy environmental footprint compared to tap. One life-cycle study in Barcelona found impacts up to 3,500× higher in certain categories for bottled water versus tap.
How this cuts waste: You avoid single-use plastic bottles, reduce microplastic exposure from bottled water, and save money – a bottle can cost €0.50 or €4 depending on where you are. The product is the same; the price changes with location. When it’s safe, drink tap.
Pro tip: If you’re unsure about local water, use a small inline filter or purification tabs. Most airports now have refill stations, and in Europe, it’s common to find public taps and filling points.
3) A bunch of adapters
Why: So you’re prepared for the weird situations life throws at you. I live on the road and can’t carry heavy gear. My kit has two USB-C cables (actually three—my power bank uses its own cable; believe it or not, I like white cables and keep them clean), plus a small set of adapters so I can power my kit, charge what’s necessary, connect everything to my computer and phone, and go wired to the internet when needed. I also connect to the products I’m developing and manufacturing – useful for configuration and pulling logs. Different standards exist all over the world; adapters keep me connected to whatever life puts in my way.
My rule: Only the essentials – compact items that fit in my smallest Thule accessory bag. If there’s no room, I find another solution. Thankfully, USB-C is everywhere now, so that’s my central connector.
4) Mini SSD, USB stick, and microSD (with SD adapter)
Why: Offline is what I’m used to. I still need to save, check, develop, and move files. I often need extra space for very large files and RAW photos, and my laptop’s internal drive isn’t always the best option due to its limits. A small SSD fixes that – I carry a 500 GB Samsung drive. The USB stick lets me go old-school when needed (surprisingly often), and microSD cards let me interface with my products and transfer files when required.
Bonus: All of these come in mini sizes. I also carry a tiny USB smart-card reader.
5) Packable tote and/or pack bag(s)
Why: You know the story – bags of bags. Keep one tote and a couple of mesh produce bags in your daypack. They weigh nothing and they work for groceries too.
Reality check: Even paper bags need multiple reuses to beat plastic in many LCAs. Carry a durable bag that lasts, and repair it when it rips.
6) Refillable toiletry set (ditch hotel minis)
Why: Those cute hotel bottles are single-use plastic in disguise. Many hotels are moving to dispensers and bulk; policy in Europe is also shifting away from avoidable single-use formats. Your own refillable kit is cleaner and consistent. Also, I care about what goes in my mouth and on my skin, so bringing my own toiletries helps me stay healthy and control the footprint I leave behind.
Pro tip: Solid shampoo and soap bars don’t leak and last a long time. Refill where you can.
7) Universal charger and one good cable
Why: The EU standardised USB-C across most devices to reduce e-waste and simplify charging. One charger, one cable – less clutter and fewer random purchases. My adapter set helps here too. I also carry a small USB-C power bank with a single in/out port. My main USB cable has multiple USB-C connectors that I can pair with adapters as needed.
Impact: Electronics are a fast-growing waste stream globally; only about a fifth is properly collected and recycled. Don’t add to the pile with extra chargers and mystery cables.
8) Playing cards
Moomin playing cards from Moomin World in Finland, bought with my youngest son. Cards entertain, pass the time, and create quick moments of being together – on trains, in hotels, or anywhere you don’t have other “nice” things with you.
9) Laundry slip kit
A small natural (concentrated) soap (or a laundry strip) and, when hiking, a lightweight wash bag. A quick sink wash = fewer clothes in your pack (and likely fewer owned overall) and less need for hotel laundry bags or plastic wrap. The biggest footprint reduction comes from owning fewer garments and wearing them more. I avoid plastic-heavy clothing when possible; when I do own synthetics, I choose recycled materials built to last – and keep them going with a bit of design sense and a needle.
10) Notebook + pencil
Why not only digital? I do both. I write lists, sketch, and map next steps without opening a screen. It saves random scrap paper and, honestly, helps me think clearly. A small notebook is always handy. Writing by hand also gives my hands something to do and changes posture from the phone – which, unfortunately, is one of my most-used work tools, and I can’t just switch it off given the business I run across half the globe.
