Introducing... Your Favorite Shirt

Let's face it, nobody really likes dress shirts. They tend to be pretty stiff, easily wrinkled and very unforgiving... especially if you're a big and tall guy sitting at a desk all day.

Newton's First has created your new favorite button up, blending classic design with modern engineering.

The Isaac Shirt looks and feels like a classic Oxford shirt, but we packed it with plenty of performance features to help keep you looking crisp, staying dry, and feeling comfortable.

Why Big & Tall Men Love This Item

Better shoulder placement and tapered sleeves for a cleaner silhouette that resembles a custom made shirt.

Underarm gussets to keep your shirt from riding up when you raise your arms.

Underarm venting to help your body breathe.

Longer body for better coverage and a "stay tucked in" fit.

4-way stretch provides unparalleled freedom of movement and all-day comfort.

Wrinkle resistant fabric keeps you looking your best all day, no matter how rough the day is.

Moisture wicking properties help you stay dry, even when the heat is on.

Product Size Guide

The Isaac Shirt is true to size, with plenty of room in the torso. Due to the stretch of the fabric, men with bigger bellies should be able to wear this comfortably.

The sleeves of the garment are fitted for a more tailored look. This may require a little adjustment period for men with bigger arms, but the stretch of the fabric keeps the garment feeling comfortable while showing off your biceps.

This garment comes in a Tall size, which adds an additional 2.5" to the length of the garment and 3" to the length of the sleeve.

Travis L.

I bought a Lululemon “Oxford” shirt last year in 2X. It didn’t fit and I returned it. This shirt feels just like the Lulu shirt but it’s true to size and cheaper. Wish they had more colors I’d buy them all.

Alex R.

Great fit. No baggy arms like other button ups. Great shirt.

Darren S.

As a fat guy I hate wearing button downs feeling like the buttons are about to pop off when I sit. Don’t even think about it with this shirt. Game changer.

Adam J.

Feels like a soft Oxford. Plenty of stretch. A little heavy but very comfortable.
