Why It’s Special

All good ingredients

We left out questionable ingredients like aluminum and synthetic fragrances, as well as baking soda, which may be irritating for some skin types.

Eliminates smelly bacteria

Probiotic Enzymes absorb odor, while Hops tame odor at the source, leaving you feeling ever so fresh.

Swipe on, stay dry

Silica, Tapioca Starch, and Diatomaceous Earth absorb excess moisture, so you can stay protected from midday funk and prevent your clothes from getting stained.

Unscented protection

Instead of including natural essential oils for scent, we opted for a fragrance-free formula that’s extra gentle while protecting against odor.

Q: What is the difference between Forest Fix and Hoppin’ Fresh or Base Layer?

A: All three contain the same aluminum and baking-soda free base formula! Forest Fix offers a woodsy scent, topped with bright citrus and subtle spice, while Hoppin’ Fresh is bursting with crisp, cool Eucalyptus and Peppermint.

Base Layer is unscented, making it a favorite for sensitive skin types.

Q: Will this stain my clothes?

A: Odor and stain protection—yes please! Base Layer is non-staining, so wear with confidence. 

Q: Is this product pregnancy safe?

A: Base Layer does not contain any ingredients that are commonly avoided during pregnancy. That said, we always recommend checking in with your healthcare provider about ingredient lists.

Q: How do I recycle this product?

A: Recyclable packaging for our stick deodorants is a top priority for us, and a project that we already have in the works.

In the meantime, our deodorant sticks (and most like ours on the market, sadly) can’t be recycled in typical neighborhood recycling programs.

    I highly recommend the Ursa antiperspirant for anyone looking for a reliable, skin-friendly option. After trying numerous brands, I’ve finally settled on this one due to its gentle formula that doesn’t cause any rash or irritation under the arms. What’s more, it leaves no stains on clothing and effectively neutralizes odors without any overpowering scents. I used to be a loyal user of Lab Series, but since they’ve changed their ingredients, their products just haven’t been the same. Ursa has proven to be a superb replacement, delivering excellent value for the price. I’ve stocked up for myself and even introduced it to my daughter, who has also made it her go-to choice. Trust me, you won’t be disappointed with this antiperspirant!

    Works well and doesn't leave marks on my clothes. Wish they'd make a travel size in this one!

    The only deodorant for me!

    I am a very active person with very sensitive skin. I've tried just about everything on the market and base layer is the only thing product I have encountered that does the job and doesn't leave my underarm irritated. Base layer is the best product on the market.

    This is the only natural deodorant that actually works. It fully deodorises and has no discernible odour of its own (I find the fragrance in natural deodorants often seems to accentuate and worsen BO.)

    Love the huge size - gets your pit in one swipe, and lasts for ever. Product has great glide, no tugging. No marks on clothes. Just bought for my 11 year old as her first deodorant, and am thrilled to save her from 20+ years of trying rubbish ones. 10/10 no notes. Oh wait - please bring back the travel size!

    The best

    My new favourite deodorant.. I have used all natural deodorants before, but I find that they either leave white marks on my clothes, or they leave my armpits sticky. This deodorant is absolutely the best.
