The Khaki Rothco M-65 Field Jacket is a heavyweight winter jacket for men, made from durable cotton-poly twill with a removable quilted liner, four snap-flap pockets, and an adjustable hood, designed to keep you warm and dry in cold, wet conditions.

Winter Jacket for Men: Rothco M-65 Field Jacket in Khaki

When temperatures drop, most jackets fall into one of two camps: warm but bulky, or lightweight but useless in real wind and rain. The Rothco M-65 Field Jacket in Khaki avoids both problems. It’s built on the same military field-jacket pattern that’s been trusted for decades, finished in a neutral khaki tone that works over a suit as easily as it does over work boots and denim.

Winter jacket for men is a genuine Rothco-spec winter jacket for men, not a thin fashion copy. The heavyweight cotton-poly shell, removable insulated liner, and storm-flap closure are all built for actual cold-weather use, not just cold-weather looks. Below, you’ll find the full details on materials, warmth, fit, and care, plus honest answers to the questions men ask most before buying a winter jacket for men.

Why Khaki Is the Most Versatile M-65 Colorway

Khaki sits in a sweet spot other colors don’t: darker and more rugged-looking than tan, but far more neutral than olive drab or camo. That neutrality matters more than people expect. Cold-weather safety guidance from the Centers for Disease Control and Prevention emphasizes wearing proper insulating layers in winter conditions, and a khaki field jacket is easy to layer over a sweater, flannel, or dress shirt without looking mismatched, whether you’re headed to a job site or a weekend outing.

• Closure: Zip-front with a snap-down storm flap to block wind and rain
• Cuffs & waist: Adjustable button cuffs and a drawstring waist for a draft-free fit
• Color: Khaki, a neutral tone that pairs with work, casual, and semi-dressy outfits alike
• Sizing: True-to-size military cut with room to layer heavier winter clothing underneath

Built for Real Winter Conditions

A winter jacket only earns the name if it actually blocks wind and holds heat. The M-65’s storm-flap front closure and adjustable hood, cuffs, and waist all exist to seal out drafts, while the removable quilted liner adds a dedicated insulation layer for the coldest months. Layering guidance from outdoor-focused publications like Backpacker Magazine consistently points to winter jacket for men kind of shell-plus-liner system as more adaptable through a full winter than a single fixed-insulation coat, since you can adjust warmth day to day instead of overheating or freezing in one fixed setup.

An Adventure Jacket That Doesn’t Look Like One

A lot of “adventure jacket” marketing leans hard into technical fabrics and bold branding. The Khaki M-65 takes the opposite approach: proven field-jacket construction, dressed in a color that doesn’t scream outdoor gear. Adventure and travel gear editors at outlets like Huckberry have repeatedly highlighted classic military-inspired field jackets as some of the most durable, low-maintenance options for men who want one coat that covers travel, work, and weekend trips without needing a separate “technical” shell. Style guides from The Manual and GQ echo the same point: a well-cut field jacket in a neutral tone reads as intentional, not tactical-costume, which is exactly the gap khaki fills between olive drab and camo.

If you’re comparing this winter jacket for men against dedicated hunting or expedition outerwear, retailers like Cabela’s and gear roundups from Uncrate are useful reference points for what “adventure-ready” typically means in terms of pocket layout, closures, and liner systems, most of which the M-65 already covers as standard equipment rather than premium add-ons.

Khaki M-65 vs. Other Rothco Field Jacket Colors

Fabric, Fit & Care

The khaki shell is a heavyweight cotton-poly twill, chosen for its resistance to tearing and general wear-and-tear over a full winter season. For care, general clothing-maintenance guidance from sources like The Spruce recommends washing heavier twill fabrics cold, skipping high heat in the dryer, and re-treating the shell with a water-repellent spray periodically if you’re wearing it through wet winter weather often. Wash the removable liner separately from the shell for best results.

Fit follows the same true-to-size military cut used across the M-65 line: roomy through the shoulders and torso for layering, with adjustable cuffs, a waist drawstring, and a two-way front closure so you can dial in warmth as temperatures shift. If you plan to wear it over a heavy sweater or thermal base layer for deep winter, sizing up by one size is a common recommendation.
