I Thought Athletes Just Slapped Their Name on Products - Then I Saw What Tatum and Bellingham Actually Did With Onside

By Marcus R. July 26, 2026

I've seen a hundred athlete "collabs."

Usually it's a logo slapped on a bottle and a paycheck.

Onside felt different the moment I looked into it.

1. This Wasn't a Weekend Photoshoot

Jayson Tatum didn't just show up for a launch event — he spent close to three years testing formulas at home, giving feedback on scent, texture, and performance before anything hit shelves.

2. Two Elite Athletes, Two Different Worlds, One Standard

Boston Celtics forward Jayson Tatum and Real Madrid's Jude Bellingham don't share a sport, a continent, or an offseason.

What they share is a routine built around movement and a brand that was designed around exactly that.

3. Built for "Skin in Motion"

The aluminum-free deodorant uses magnesium hydroxide for odor control, tapioca starch and baking soda to manage moisture, and shea, niacinamide and jojoba to keep skin from feeling stripped.

Nothing about it reads like a gimmick built around two famous names

4. It Works Beyond the Highlight Reel

The real test for a deodorant isn't the sprint or the match. It's the flight after, the press conference, the commute the parts nobody films.

5. Under $20, Not Behind a Velvet Rope

Despite the star power, every hero product is priced under $20 accessible, not a luxury flex.

Finally no burn

"Switched from a baking soda deodorant that literally left a rash under my arms. This one doesn't sting, doesn't itch, and still does the job by end of day. Wish I found this two years ago."

Actually works past noon

"Was skeptical because every "natural" deodorant I've tried quit by lunch. Went through a full workday plus the gym after and still smelled fine. Not gonna lie, I sniffed my pits like an idiot to check."

Got this for my husband

"He's picky about smell and skin stuff so I wasn't expecting much. He's used it two weeks straight now and hasn't gone back to his old stick once. That alone tells me it's a keeper."

No white marks on shirts

"This was my main complaint with every other natural brand, chalky streaks on my black shirts. This one goes on clear and doesn't leave that weird sand texture either. Small thing but it matters daily."

Skin finally chill

"Have sensitive skin and most deodorants make me break out or burn after shaving. Zero issues here. Just wish it came in a bigger size honestly because I go through it fast."

Smells like a person not a candle

"Got the Santal Leather one and it's subtle, not overpowering. Doesn't clash with my cologne which was always an issue before. Feels like it's actually working with my skin instead of masking stuff."

Didn't expect to care this much

"Bought it on a whim during a sale. Didn't think a deodorant could make me write a review but here we are. It just quietly does its job all day, no drama, no smell breaking through."

Long shifts, still fresh

"I'm on my feet 10+ hours at work and sweat a lot. This held up way better than the drugstore stuff I used before. Only bought it for the ingredients but staying for the results."
