Carry-on luggage and men's underwear, a packing list

Short answer: For carry-on luggage, three to five pairs of bamboo underwear are enough if you wash along the way. They are soft, take up little room and dry fairly quickly, so your bag stays light. Here is a simple packing list that works for business trips and weekend breaks.

How many pairs to bring

A good rule is one pair per day for up to three days, then wash in the sink in the evening. For a week away, five pairs is a safe starting point, so you are never caught short by a delay. Add one extra pair if you plan to exercise or expect warm weather.

Bamboo underwear in a small bag

When space is tight, the fabric matters, because thick cotton fills a cabin bag quickly. Underwear made of bamboo is usually thin and flexible, so it can be rolled tightly and tucked into corners. Look at bamboo underwear for men in a fit you already know, so you are not experimenting while travelling.

Fit on a long travel day

After eight hours in an airline seat you notice every hard seam and every waistband that is too tight. Choose styles without inner labels, and wear them for a full day at home before they go in the suitcase. If they feel good at your desk, they usually feel good at the airport too.

Washing in the hotel sink

A pair washed in the evening is usually dry by morning if you hang it with air around it. Use a little mild soap or hotel shampoo, rinse well and roll it in a towel to press out the water. Avoid the radiator, since strong heat can wear on the fibres, and always check the care label.

The right pair for the road

Bamboo boxer briefs in a short or mid length suit most occasions, under a suit as well as with jeans. Pick dark colours for a long trip, since small stains and wash marks hardly show. Stick to two or three identical styles, so you can switch without thinking about it.

One more layer when it gets cold

If you are heading somewhere cooler, a thin layer under your shirt adds almost nothing to the load. Long sleeve models work as a base layer and as a relaxed top in the hotel room, so they do two jobs. You stay warm without an extra sweater, and rolled up they take almost no space.

Socks and small things

Socks follow the same logic: bring one pair more than you have sets of underwear, and choose pairs that can dry overnight. Stuff small items into your shoes to use the space. A small laundry bag keeps worn clothes apart from clean ones and keeps your luggage tidy for the whole trip.

A checklist before you zip up

Before you close the bag, count the pairs, socks and the extra layer, and put one set in your handbag in case the suitcase goes missing. Then check that you have something to hang things on in the bathroom. That covers the essentials, and the rest of the trip can take care of itself.

Frequently asked questions

How many pairs of underwear should go in a carry-on

Three to five pairs are enough for most trips if you wash along the way. Choose thin fabric that dries quickly, and bring one extra pair in case of delays.

Can I hand wash bamboo underwear in a hotel sink

Yes, lukewarm water and mild soap work well. Rinse thoroughly, roll it in a towel and hang it with air around it, and it is usually dry by the next morning.

Should I roll or fold the clothes

Rolled usually takes the least space and is gentler on seams and waistbands. Tuck the small rolls into corners or inside your shoes to make the best use of a carry-on.
