Irish Spring has been in American showers since 1972, and there's a good chance the first bar of soap you remember was green and white and smelled like a very clean field. So is it any good? For what it sets out to be, yes. It's real soap, it's cheap, and you can buy it anywhere at any hour. Whether it's the right bar for you depends on how you feel about a strong fragrance and a couple of dyes.
What's actually in it
The current US Original bar is true soap, not a synthetic detergent bar. The label lists soap made from plant fatty acids first (sodium laurate, linoleate, oleate and palmitate, if you like the long names), then water, glycerin and fragrance, with a little flaxseed oil further down. Then come the things that make it look like Irish Spring, titanium dioxide for the white swirl and two dyes, Green 8 and Green 3.
Some international versions of the bar list sodium tallowate, which is soap made from beef fat. If that matters to you, read the label on the box you're holding, because formulas vary by country and change over time.
The smell
This is the whole personality of the bar. It's strong, it's fresh in a specific and instantly recognizable way, and it lingers. Fans love exactly that. People who don't like scent hanging around after a shower tend to find it a lot. If fragrance is a problem for you, this isn't the bar.
Is it antibacterial?
The Original bar isn't. It's sold as a deodorant soap, which is a description of what it's for rather than an added germ-killing ingredient. Some Irish Spring products are labeled antibacterial, and you can spot them by the Drug Facts panel on the package. For everyday washing, the FDA has said there's no evidence that consumer antibacterial soaps work better than plain soap and water anyway.
Where Irish Spring wins
Price, for one. At $6.39 for eight bars at Target, it's well under a dollar a bar, and nothing handmade is going to touch that. Availability, for another. Every grocery store, drugstore and gas station seems to carry it. And it's consistent. The bar you buy today is the bar you'll buy next year.
It has a second career outdoors, too. A lot of gardeners hang it in mesh bags or shave it around plants, which we covered in what Irish Spring soap repels.
Where we'd make a different case
We make our soap by hand in small batches with organic oils, and we'd rather a bar smell like bergamot and burnt lumber than like a commercial. You can also get one of ours with no scent and no color at all, our Castile Soap, and as plain as a bar gets.
We cost more. That's the honest trade, and the table above lays it out. If you love Irish Spring, keep buying it. If you've started reading labels, or you're curious what a bar made by people instead of a plant feels like, the men's bars are a good place to start. And if you want the bigger picture, we compared six bars side by side in the best bar soap for men.
