We spend a lot of time curating our daily rotation: the right watch, the right fragrance, the right skincare regimen. Yet, most men overlook the small, habitual things. Chewing gum is usually an afterthought, grabbed in a checkout line. But Underbrush Gum by Nathan & Sons is making a strong case for turning this mindless habit into a functional part of your grooming routine.

A tool for facial definition

There is a reason this gum has quietly become a favorite among the aesthetic-focused crowd. Unlike the soft, mass-market options that lose texture in minutes, Underbrush offers a noticeably stiffer chew.

It functions as a low-impact resistance tool. While trends like “mewing” often overcomplicate things, the logic here is straightforward: engaging your masseter muscles leads to better tone. I’ve found it to be a simple, analog way to work on facial definition and jawline structure without adding a new step to my morning workout. It feels substantial, satisfying, and intentional.

Quality ingredients, zero synthetics

For the discerning man, the ingredients list is just as important as the utility. Most commercial gums use a base made of synthetic plastics and rubbers. Underbrush removes the synthetics entirely.

It is plastic-free, sugar-free, and formulated with remineralizing ingredients designed to support enamel strength rather than just mask odors. It feels cleaner because it is cleaner. It represents the same shift we have seen in natural deodorants and clean skincare: choosing a product that works with your body, not just on it.

The bottom line

We are in the era of optimizing the everyday. Underbrush turns a disposable commodity into a wellness investment. By setting up a subscription, you ensure your carry is always stocked without thinking about it. Use code SUBSCRIBE15 to upgrade your routine for 15% less.

Keeping your car interior clean sounds simple until daily life takes over. Between spilled drinks, muddy shoes, wet umbrellas, and sand from weekend trips, floor carpets can become a disaster zone in seconds. Standard carpet mats offer some protection, but they can only do so much when dirt and liquids make their way past the edges.

Swiss watchmaking at this price tends to split into two camps: watches that look the part but don’t show you anything, and watches that give you a window into the movement underneath. The Frederique Constant Highlife Heartbeat FC-310N4NH6B sits firmly in the second group. It’s down to $1,649 at Amazon, a $546 saving off its $2,195 list price, and the open-heart aperture at 6 o’clock makes it one of the more visually interesting automatics available at this price right now.
