    Does this beat Anthony Invigorating wash in the long last smell
    Scent: Seagrass & Driftwood, Size: 32 Fl Oz (Pack of 1)
    Anthony Invigorating wash (check out my review of that) has a very strong pine scent to it and is a very long lasting smell. How does Cremo's products stand up to it! I put deodorants, shampoos, and body washes through the same rigorous tests. I run 14+ miles 4-5 times a week, swim 20+ lengths (or laps) in a junior Olympic pool 3 days a week, use a Sauna 2-3 times in fifteen minute intervals 4 times a week, and use weights 4 days a week. All of these body washes and shampoos that I try out not only go up against Anthony's but also getting rid of that chlorine smell. I always will finish a product before reviewing it I'll be honest here as always, the Blue Cedar and Cypress at first whiff smelled weird. I can't explain the 1st whiff smell though you have my warning. I thought this was going to be my least favorite of the 3 different Cremo products (bourbon and oak, seagrass and driftwood, and this one) that I received. I have the policy to use all the products up in their entirety, so you don't have to. After using it up, I actually like the smell of it. The cedar smell comes out once applied. I actually use this with Anthony Blue Sea Kelp Body (check out my review of that). This goes great with it. So on my buy, borrow, or bury review rating system, this is a buy. The issue I have with it, is that Cremo products don't seem to be that moisturizing their smells are good and lasting. This beats the off the chlorine smell of the pool and works great in combination with Anthony's. Try it out, just get past that initial smell, you won't be disappointed. Now for Cremo's seagrass and driftwood. The First smell test of it is very pleasant. It's once you've put it on does that wood smell really come out. The smell is good and does last long though the issue I have that it is not moisturizing. This goes great with Anthony's other 2 products that I have viewed (please check those out). So on my buy, borrow, or bury rating scale, this is a buy. If they could make their products more moisturizing it would be fantastic. I'll be back here to review the Bourbon and Oak, I have not finished it yet though it's probably going to be my favorite of all the 3 Cremo products I've tried out. Please check out all of my other reviews!

    Great buy!
    Scent: Palo Santo, Size: 16 Fl Oz (Pack of 2)
    This is my favorite brand and the lather is second to none! The smell is amazing and the quality is worth the extra price. It leaves my skin feeling moisturized and soft.

    FINALLY. THIS IS ACTUALLY WHAT YOU WANT.
    Scent: Seagrass & Driftwood, Size: 32 Fl Oz (Pack of 1)
    I’ve tried all of the soaps. All of them. Molten brown sucks, 18.21 sucks, Blackwood sucks, and brickell sucks. All I wanted is a premium soap that doesn’t suck. All I wanted is to feel good and smell good. I work in kitchens, so I’m not some desk monkey needing to wash off the stale air, I have to actually clean myself. I don’t even know how these soaps stay in business, you might as well be using Irish spring and save the money. Nothing moisturizes, I’m always left with dry skin, or the smell lasts all of 6 minutes. Until now. This stuff is actually the luxury brand I’m swearing by. It lasts on my skin, it lathers well, it cleans well, and it doesn’t give me itchy skin just to smell nice after a shower. Also, it doesn’t cost $36 per bottle like molten brown does for 2 teaspoons of soap with gold flakes in it that smells great for 6 minutes. It’s cheaper, and you get more.

    Long Lasting Scent
    Scent: Bourbon Oak, Size: 16 Fl Oz (Pack of 2)
    I've tried dozens of different brands of body washes and have had various objections. This is the best by far in every metric. First of all the scent. Bourbon & Oak. I'm not convinced that it smells like bourbon OR oak. It's definitely a warm musky scent and I would say it tends more towards a creamy spice with a strong low note. Longevity: My job is about 50 percent physical throughout the day and I tend to shower only at night when I get home from work. This is the only body wash whose aroma not only lasts through the rest of the evening, but well into late morning the next day. I would even say that physical activity brings out a very smooth and subtle character. This is the first time I've ever been able to smell a body wash the next day. It was surprising and pleasant. As for moisturizing, my skin feels smooth but without the oily residue that I typically associate with moisturizing products. If a product lives up to my expectations I tend to leave a simple review and fair rating. For products like this that exceed my expectations I try to leave a more detailed review that highlights its strengths. I will most certainly continue to use this brand and experiment with the different scents available. 10/10 would recommend.

    Please do NOT reship items like body soap that have been returned
    Scent: Seagrass & Driftwood, Size: 32 Fl Oz (Pack of 1), Scent: Seagrass & Driftwood, Size: 32 Fl Oz (Pack of 1)
    So I've purchased this twice now, I love the scent and I love how it lathers up, overall very happy with the produce so long as I get a product that wasn't previously returned. The 2nd order I received, it was clear that someone had replaced the soap in the bottle with some other kind of liquid and returned it and I got it. First off that has to be dangerous and hazardous. As you can see from the pictures, something is wrong with this product. The first product I got had a clean scent, was clearly a body soap liquid. The 2nd product I ordered was more water, smelled had virtually no scent at all. Unfortunately I had already poured it into my soap dispenser so it's now not returnable. PLEASE DO NOT SHIP OUT RETURNED ITEMS!! It's dangerous
