Carl Friedrik has launched its first aluminium carry-on case – and we were among the first to put it to the test

On the flip side, for all the additional style points, it’s slightly less practical than the brand’s existing Hybrid model. While virtually identical in size, the Aluminium Carry-On offers 38 litres of capacity to the Hybrid’s 40, and is around half a kilo heavier. If you’re a strict carry-on-only traveller – even on long-haul trips – that marginal loss of space may matter. That said, it still feels impressively lightweight, and I was able to lift it into the overhead compartment unaided – which I can’t always do when testing suitcases.

A closer look at the details

One important – and neutral – point: aluminium will dent in a way that polycarbonate won’t, regardless of brand. Personally, I like the idea of a suitcase developing a unique pattern over time – a visible record of a life well travelled. After all, this is a buy-it-for-life purchase. After two of our three test trips, small dents had appeared in the shell. If that doesn’t appeal, you may be better off considering a polycarbonate alternative – see our favourites in our luggage guide.

The exterior

The cognac colourway goes perfectly with a classic tan leather handbag

Forged from anodised aluminium, this is Carl Friedrik’s most hard-wearing cabin case yet, with new steel rivets adding extra protection against knocks and bumps to complement the robust aluminium frame. As expected with this material, the case will develop a patina over time, developing into something richer with age – this is something I find rather romantic, like a well-loved leather handbag that softens with age.

There are three leather finishes available for the handles and accents – cognac, black and chocolate – all designed to pair with the brand’s backpack and briefcase ranges for a cohesive set. We chose the cognac, which goes well with a classic tan leather handbag – a truly versatile choice.

The interior

I packed comfortably for three nights in Milan and Paris: a couple of outfit changes, pyjamas, gym kit, a washbag and a spare pair of shoes. For warmer destinations where you’d prioritise packing lighter fabrics, you could likely stretch this to four or five days’ worth of clothing easily. I also lent the case to a colleague for Lisbon, who managed five days’ worth of packing with ease – and said she could have got in more. Ultimately, capacity will depend on how heavy a packer you are, but it’s ideal for a long weekend during the winter at minimum.
