I can breathe so much better.

Every spring I'd dread that heavy, congested feeling when the pollen came around, like I couldn't get a full breath. This year I actually made it through without that. The only thing I did differently was the L Max.

- Lucy B.

The first few days I wasn't sure I felt much. Then on day four—the magic day—I ran a 10K and realized my breathing just felt clear.

Kelly Y.

I PR’d my half marathon.

I PR'd my half marathon by 8 minutes on an extremely hilly route! And I did a 30-minute bike ride for brick training before the run.

- Kayla H.

I've been skiing my whole life. Climatic is the only thing that helped me perform better at high altitude in years.

- ANDY M

I can't explain how much Climatic has changed my breathing. I finally feel like I can take one huge deep breath on my rides without issues.

Kate M.

This is a game changer.

I used to cough for 2 days after running races, but with Climatic, I barely cough at all. I can breathe so much better during races, which have helped me keep my race times where they were a few years ago. Climatic is an exciting find for an aging (but competitive) athlete!

- Michelle K.

12/10

Honestly didn't expect much, but a few weeks in I just…felt better. Breathing easier, more energy, less foggy. It's become one of those things I don't even think about skipping anymore.

- Emily C.

    Love this!!

    My L Max refills are so helpful for travel. I will order two or three packs so I can easily throw it in my bag. My L Max helps my allergies SO much. I feel like my chest is clearer because my lungs are clearer.

    Positive results!

    I'm so pleased with how helpful L Max has been in reducing my congestion during this awful allergy season! I look forward to receiving my next refill.
