My travel/shave routine consist of shaving oil and a new disposable twin blade lubricated strip razor for each shave.
I half fill the sink with hot water and dunk and tap the razor after each stroke to clear the blade of oil/hair/skin cells.
WalMart sells a 2 oz. bottle of shaving oil for less than $3.75, and
I use this along with a new disposable twin blade lubricated strip razor(Good News type) but usually purchase the cheaper Target/WalMart generic version, usually 12 for less than $2.50.
In the past I have been able to make a disposable razor last for quite an extended period of time but as I get older I like to start fresh with each shave to minimize cuts and irritation to my face due to a dull blade.
My system addresses the issue of size/weight and minimal cost for a backpack traveler like me.

Somerset's Original shaving oil and Gillette Mach 3. No problem of clogging with warm water and a drop of soap in the water.

Nancy Boy Signature Shave Cream or Nancy Boy Replenishing Shave Cream

Best I have ever used and I have tried all kinds of creams, soaps, oils, etc.

They sell a 2oz travel size as well as a full 6oz size.

I like Dr Bronners for showering and hand washing travel items, but I din't find it to be good for shaving. I can get an OK shave from regular shaving cream.

After reading various travel sites, i decided to give the Pacific shaving oil a try. I wasn't particularly optimistic about a little oil being effective.

I am happy to report that I am enjoying shaving with it it after showering. I find that it works best if i put some water over the area to be shaved just before applying the oil. It takes 8 drops for me.

I use the cheap disposable single blade razors.

I've been a wet-shaver for decades and use a brush and soap. For travel I use my Simpsons Wee Scot and a Valobra or similar shave stick; both fit well in their own small prescription bottle with small holes drilled for air flow to dry. I also use a double edge razor and since those blades are not allowed as carry on, I also pack a disposable in case I can't find DE blades quickly at my destination ( or send blades to my hotel in advance with my name and check in date asking to hold for arrival).
Since TSA will always check my bag with a DE Razor, I keep that in my quart liquids bag so they don't have to open my bag needlessly.

I have tried shaving creams and gels, but I find that oil works best for me. Any decent quality oil will work. I first tried Shave Secret, but I have found plain almond oil works best for me.

Regarding the frequent comments about the razor clogging with shave oils - the trick is to wash out the razor several times during a shave. I sometimes use a mug of hot water for this purpose. It keeps the razor wet and rinses it each time you swish it around in the mug.

As far as razors go, I use a Gillette Fusion ProGlide at home, but use a normal Gillete Fusion while traveling.

Just ordered the Merkur travel razor. [1] Finally I'll have a full dopp kit ready to go at all times. I don't really know why, it's not like I could take a trip without planning and scheming for at least a week beforehand. I'm not exactly known for my spontaneity...

Just as a quick report, the Merkur is just as excellent as I expected. It's insanely compact, comes with a rather elegant leather case with snap closure and gives a really good, medium to aggressive shave. It's rather light but not overly so and surprisingly well balanced. The two-part handle is hollow and the parts can nest together when not in use. I might end up buying a regular model to complement my Mühle-made Edwin Jagger at home.

It's true that DE shaving is not ideal for air travel. Luckily the blades are pretty easy to buy at most destinations. Also, my most typical travel scenario is a few nights domestic bus or train trip to see my family or friends. It's a nice luxury to be able to have that familiar shaving experience on the road.

DON'T

The best solution is don't shave. Grow a beard.
Works for me.

Enjoy the video which went viral.

I sport a beard and it makes things easier since I only need to shave my neck and very little of my cheeks. My skins is so sensitive I use Shave secret oil and fusion pro-gluide at home. When traveling I use that same type of retractable trac-II blade system if it is only for a few days other wise the fusion will have to go with me.

Shave sticks (and a cheap badger brush) are where it's at. A solid bar of shaving soap molded into a small cylinder. I've kept a Boots brand one in my dopp kit (with a $10 Tweezerman brush) for a couple of years now and haven't come close to using it up.

Maybe not as compact as Pacific Shaving Oil or Somersets, but the quality of the shave is much improved. Especially if you're shaving with a cartridge system which, as a carryon traveler, you would be.

For about 9 months now I have been using a shaving package as follows:
1. Homemade shaving oil in small plastic bottle where you squeeze the drops out. (I think it used to be a Murine bottle.)
2. Homemade shaving lotion in small plastic bottle with a flip top lid.
3. Disposable safety razors that come in packs (4, 6, 8, etc.) like you can find in Walmart and other stores.

For the shaving oil, I watched some Youtube vids and read some internet posts. In my case, I used sesame oil (not the type on your Chinese dish food!) with peppermint essential oil. Used about 1/2 ounce sesame and about 12 drops of essential oil. You can experiment with this and create what you like. Big advantages to going this route. First, I feel better using the oil versus the usual lather spray. Second, once you already have your oils, your cost is lower over the long run. Third, your weight/volume is very much less. You only need 4 to 6 drops for shaving. Works best right after shower.

For the lotion, I use a mixture of vodka (yes, that's right, Vodka!) and an essential oil. In my case I chose lavender. Just like the oil, you can use any essential oil you want at any strength that works for you. I suppose you could use other alcohol, like gin. YMMV.

Now for a bit of humor for you ladies in the non-shaving category. If you are single and want to attract a real man, get a bottle of Hoppe's Number 9 gun bore cleaner. Men will recognize this attractive smell from over 200 yards away! Just a few drops behind each ear and you are set! But, be ready for men to flock to you! Heh, heh.

I have both of these and I like them very much. So far I have really only been using the Valobra. I have had it in my dopp kit for a couple of years and have used maybe 1/3 of the stick. I am not sure how they would do for sensitive skin, or if they offer a version specifically for sensitive skin.

I also have a Taylor of Old Bond Street jar of the sandalwood which I like very much. I've been thinking of packing some of that into a small jar or tube. You could put some of that into a go tub very easily and without a big mess. I know they offer a sensitive skin formula.

Don't want to hijack this thread, but...

Anyone have any recommendations for a good travel electric shaver? I have an old Norelco triple rotary which is on its last legs. I'm going to need something for trips longer than two weeks, so I'll need to recharge (or replace batteries). Looking for something lightweight primarily (including charger), but that will hold a decent charge. The USB shavers from Braun and Shavetech look interesting. I know that Panasonic makes great shavers, but they all seem to be bigger.

I wet shave and prefer to use Wilkinson Sword (Schick) razors. I use 'Somerests shaving oil'. A 15ml bottle will last me 3-4+ months - using 3 drops each time. You can always de-cant it to a smaller (5ml?) bottle.
