MuskOx was founded to create rugged, timeless American menswear that supports wildlife conservation. They focus on ethical manufacturing in Portugal (known for the world's best flannel mills) and donate $5 from every flannel purchase to the Alaska Wildlife Conservation Center to support wolves, bears, and bison. When you buy this shirt, you are supporting the wild.
Rated "Best Heavyweight Flannel" of 2025 by GearJunkie
The MuskOx Grand Flannel in Charcoal Gingham is the definition of "rugged yet refined." Rated "Best Overall Flannel" (2023-2024) and now the "Best Heavyweight Flannel" for 2025, this shirt proves that you don't have to sacrifice style to get serious warmth.
We selected this specific pattern for the Kempain Family Outfitters Mercantile because of its versatility. The classic Charcoal Gingham check is sharp enough for a casual office or holiday dinner, but the construction is 100% field-ready.
Why It's a Customer Favorite:
- The "Go-Anywhere" Pattern: The Charcoal Gingham strikes a perfect balance. It pairs easily with dark denim or chinos for a clean look, but hides the grit of a day’s work just as well.
- Heavyweight Warmth: Clocking in at a massive 8.9oz per square yard, this is two times heavier than the average flannel. It provides reliable warmth without the bulk of a jacket.
- Double-Brushed Comfort: MuskOx brushes the fabric on both the inside and outside. You get a crisp, structured look on the outside with a blanket-soft feel against your skin.
- Ethical Craftsmanship: Expertly woven in Portugal from 100% ethically sourced cotton.
The Kempain Promise: This is the shirt you grab when you need to stay warm all day but still want to look put-together when you walk through the door at night.
