Overview
Armed with NEMO’s top-performing OSMO™ fabric on the fly, Mayfly OSMO™ is a notably durable backpacking shelter for adventurers ready to hit the trail. A proprietary composite fabric, OSMO is made from 100% recycled polyester and nylon yarns and scores 4x better in water repellency than standard tent fabrics — all while stretching 3x less when wet. OSMO fabrics meet fire retardancy standards without the use of added chemicals and are treated with PFAS-free waterproofing.
Paired with the OSMO fly is a super-durable ripstop tent floor that can withstand the not-so-precious treatment that comes with life on the trail. Mayfly OSMO’s massive doors and generous headspace, however, feel anything but rough — there’s ample room for two to comfortably sit side by side.
Featuring NEMO-exclusive Elements™ hardware, this semi-freestanding tent offers an easy, intuitive setup that’s highlighted by the Axial™ corner anchors, which allow for connection and adjustment in one streamlined piece. A Divvy Cube™ stuff sack completes the package for efficient storing and splitting the weight with a friend.
- bluesign® approved OSMO fly meets strict ecological and chemical requirements and has been produced with a minimum impact on people and the planet.
- High-performance, high-strength OSMO™ poly-nylon ripstop fabric has 4x longer lasting water repellency and 3x less stretch when wet. OSMO fabric is made from 100% recycled yarns that are PFAS-free and meet flame retardancy standards without the use of added chemicals.
- Super-durable 68D PU ripstop floor withstands rough treatment on the trail and helps your tent last even more seasons.
- Massive doors and generous headspace allow for side-by-side seating.
- Divvy Cube™ rectangular stuff sack allows you to split the weight with your partner, but stows more efficiently in your backpack.
- Hubbed, pre-bent aluminum poles with a high-arching main pole to significantly increase volume at the head and foot ends.
- Color-coded webbing and NEMO-exclusive Axial™ corner anchors create a smooth, intuitive setup experience.
- Tapered floorplan saves weight while giving backpackers space where they need it most.

good product
Effectiveness:
This serum focuses on brightening, uneven tone, and early signs of aging using two stabilized forms of vitamin C plus supportive antioxidants. With consistent use, it can help improve overall radiance and reduce the look of dark spots gradually rather than delivering fast, dramatic fading.
Texture & Application:
Lightweight, silky, and smooth. It spreads easily and absorbs quickly without feeling greasy or heavy. The airless pump helps keep the formula stable and prevents oxidation, which is important for vitamin C products.
Key Ingredients Performance:
Vitamin C (two stabilized forms) supports brightness and antioxidant protection
Kojic acid ester helps even skin tone over time
Oryzanol (rice bran antioxidant) helps enhance brightening effects and supports skin defense
Overall, it’s a gentler vitamin C approach compared to high-strength L-ascorbic acid serums, making it more suitable for sensitive or beginner users.
Skin Feel / Finish:
Leaves a soft, natural finish with no sticky residue. It layers well under moisturizer and sunscreen and doesn’t pill when used correctly. Suitable for daily AM or PM use.
Durability of Results:
Improvements are gradual—typically noticeable after several weeks of consistent use. Best results come with daily sunscreen use since vitamin C works synergistically with UV protection.
Value:
Very strong value for a budget-friendly serum. It delivers multiple brightening ingredients at a low price point, making it accessible for everyday skincare routines.
Overall:
A gentle, affordable vitamin C serum that prioritizes steady brightening, antioxidant support, and skin tone improvement over high-intensity results. Best for beginners, sensitive skin, or anyone wanting a simple daily glow-boosting step.

Amazing Vitamin C at an Affordable Price!
This Vitamin C serum from Good Molecules is honestly one of the best I’ve tried! The texture feels so smooth and lightweight on the skin, it absorbs quickly and leaves my face feeling hydrated without being sticky. It’s super effective for fading acne scars and dark spots, and I always notice extra brightness and glow the next morning after using it.
What makes it even better is how affordable it is compared to other Vitamin C serums—such great quality for the price! Plus, the bottle lasts a long time since just two pumps are enough for the entire face. Gentle scent, hydrating, effective, and budget-friendly… I couldn’t recommend it more

Fantastic Fragrance Free Vitamin C
Really nice Vitamin C product. It goes on nicely without any off putting scent. I tried this one after trying another Vitamin C serum my dermatologist recommended, but the consistency and smell of the other one makes this one a dream to use in comparison.
Instead of a dropper, it is dispersed using a pump. The consistency is thin, but not watery. It does not leave my skin feeling sticky. I love not having it drip all over my face. Leaves a nice glow without being shiny.
Time will tell how effective it is at fading brown spots, but as with the other Good Molecules products, this is a great product for a great price.

Great buy and a have to try
This is a very nice vitamin C serum/cream. It spreads nicely, so you do need a lot. A little really does go a long way. I wash my face, apply serums, and then apply this on top before my moisturizer. It doesn't pill up at all for me. In fact, it layers really well. It's dry time is fairly quick, and it's a GREAT value for your money. It's also not oily at all.
I've been using it for over a week now and I can tell my complexion is brighter and the one dark spots are s bit lighter. I'd say it's pretty effective.
