bag/container for work shirts

Most of the time I drive in Monday, take everything for the week, and return the dirty clothes on Fridays drive in. If I want to ride more I just roll my shirt/trousers and put it in my rucksack..doesn't get badly creased and my pack is weatherproof. 

I use a Henty Wingman suit carrier. I take 6 shirts at a time and hang them at work.

I know theres a company that makes bags for carrying suits on a bike. Might be worth a google to see if they do a smaller version for shirts?

I roll up the shirt and also use a compression bag like this

This removes all the air from the clothes in the bag and so they take less space in a rucksack or pannier

Used this for years. It comes with a stiff removable plastic sheet and instructions on how to fold for that shop look. Great for holidays too. Can easily fir 2-3 shirts, or shirt and trousers. Nowadays I use the sheet to fold a shirt, then roll it up and place in a small decathlon frame bag. Trousers stay at work, changed every few weeks.

Also depends on what shirts you wear, non-iron definitely crease less when folded or rolled than a normal shirt..

Totally agree with the rolling: I fold it "shop style"  (do shirt up, lay it face down, fold arms in, fold body/sides in, bottom third up, top third up - only every other button done up if I'm being lazy - but always with the collar fastened), then roll it up (you can afford to do it quite tightly - too loose and creases form!)...laid at the top of the rucksack or pannier, no real issues.  - Also agree that rubble sacks are the best rucksack/pannier liners you can get: cheap and tough, waterproof, last ages.

I had one of the first shirt shuttles years ago (in fact I think I bought it at The BIke Show...), and I found it creased shirts far more than it protected - and took up massive amounts of room in my pack!

Do you need to shuttle shirts back and forth?  I get my shirts washed and ironed for a quid each, just around the corner from the office, then keep them in a cupboard at work. They never need to go near a bike.

I use the car on the days when I can't cycle.

Failing that (i.e. I forgot!), I just fold the shirt neatly and put it flat in rucksack. Never creases enough to notice.

Rubble sacks - fold shirt, place in one corner of the rubble sack and fold rubble sack to fit,  Makes a reasonably taught package that survives an hour and a half in a pannier, and is waterproof, and cheap.

Another tip to add to the collection:

When folding the shirt, fold one of those dry cleaning bags (very thin plastic bag that covers suits / dresses / etc. when they return from the dry cleaner) into the shirt as you fold it.  Allows the shirt to slip, rather than wrinkle as it moves around.  For extra protection, once shirt is folded, fold another dry cleaning bag around the outside of the shirt and then place the whole lot into a plastic bag that is as close as possible to the shape/size of the folded shirt.

Whenever I travel (and when I used to commute by bike), I always fold a dry cleaning bag into my shirts.

I can 2nd rolling; lay shirt over sofa arm overnight.* Fold vertically down the front, and into the plastic bag for 20 minutes to work, very little time to crease.

*assuming pet and small humans cannot interfere. 

For 10 years I commuted every workday with a clean shirt in my rucksack.  I never resorted to clever containers, nor did my fussy employer ever complain I was crumpled.  The answer is not to fold your shirt but to roll it gently into a tube-shape and put it on top of everything else in the bag.

( I won't mention the morning I forgot to zip up the bag and it rained torrentially all the way to work.)

I’ve used the shirt shuttle (rigid plastic box with a polystyrene centre block) with some success. Although it was only slightly more effective than folding around a magazine and putting it in a carrier bag.
