Small handlebar bag

I'm looking for a small handlebar bag to use on longer rides and see a lot of cheap bulky options out there. Any recommendations? 

I like my Revelate Egress.  Not the best as a stand alone bag but have never had an issue using it that way.

I've been using the Pinon Pocket from Wanderlust; easy on/off and good volume.  The pictures from the site are on a flat bar but I use mine mostly on Cowchipper drop bars as a stand alone bag.

The Revelate site explains that if you are putting their roll style/compression sack bag on drop bars to go with the large version and just roll/compress your contents down to fit.  Their small size is smaller, which would make sense, but it is also smaller in diameter, so it holds less stuff.  Thus the large advice.

The Salsa EXP compression sack style gets good reviews for easy on-off, versatility and drop bar friendliness with it's bar clamp harness system that holds the bag away from cables and fingers.

I use a Swift Paloma.  It's terribly overpriced but I like it.  It can hold 2 protein shakers and gym clothes better than a Revelate tangle bag.

how about this one? http://www.outershelladventure.com/shop/handlebar-bag 

I should receive one for my birthday next week. It's really easy to install and remove. Can can access your stuff with one hand while riding. It's expensive but gets good reviews on the path less travelled and off.road.cc

You can use it alone or with their stuff sack harness and bag for longer ride or bike packing

I like the side pockets on the Pinon Pocket....  The Egress does not have those, but it does have a padded inner pouch that you can remove.
