Mens raincoat trench coat styles are among the hardest outerwear categories to buy well off the rack. Proportion, sleeve length, fabric performance, and silhouette all compound into a purchase that too often disappoints in fit or in weather performance. At Germain Tailors, every coat in this collection is made to order from Olmetex Italian technical fabric, then cut and assembled by hand in Shanghai. The result is a tailored raincoat that genuinely fits the body wearing it and holds up in real rain, not just a light drizzle.

Two silhouettes, both built from the same Italian technical fabric and available in seven colorways, with full sleeve and body length adjustments on every order.
The Rider Raincoat by Olmetex is a long, belted coat with a substantial silhouette designed to sit comfortably over both tailored and casual clothing. Available in seven colors with optional body and sleeve length adjustments, it is the more formal and covered of the two options.
The Mac Raincoat by Olmetex is a single-breasted mac coat with a cleaner, more understated cut. The single-breast front keeps the detail level low, making it easy to wear without the coat competing with what is underneath. Available in seven colors with the same fit adjustment options.
Both are part of the wider outerwear collection at Germain Tailors, which also includes wool and cashmere coats for colder months.
The Fabric: Why Olmetex Sets These Coats Apart
Olmetex is an Italian mill that specialises exclusively in technical coatings. Not fashion fabrics that happen to be treated with a water-repellent finish, but engineered technical fabric where waterproofing is built into the construction itself.
Most mass-market mens raincoat trench coat options use a Durable Water Repellent treatment applied to the surface of a base fabric. DWR treatments are effective when new but degrade with washing and wear, so a coat that feels genuinely waterproof in the shop may perform considerably worse eighteen months later. Olmetex fabric is structured differently. The waterproofing is inherent to the fabric rather than a finish sitting on top of it, which means performance does not degrade in the same way under normal use and care.
Beyond waterproofing, the Olmetex fabric selected here achieves four properties that are genuinely difficult to combine: strength, lightness, waterproofing, and thermal resistance. Cheaper coatings tend to trade off against one another - heavier construction for more protection, or lighter weight at the cost of warmth. The Olmetex selection avoids that compromise, keeping the coat light enough to layer over a suit jacket without bulk, while still providing real weather protection in sustained rain.
For anyone comparing this to a standard treated cotton or polyester option, the distinction is most apparent in hand and drape. Technical coating fabric moves and sits differently. It feels structured without stiffness, and does not develop the crinkled texture that DWR-treated cotton picks up after repeated wear.
Rider or Mac: Choosing the Right Silhouette
Both coats use the same Olmetex fabric and the same construction approach. The difference is in silhouette, and that difference matters for how each coat performs across occasions and dress codes.
The Rider: Long, Belted, All-Weather Ready
The Rider Raincoat is a long, belted coat with a generous, enveloping pattern. It is designed to sit comfortably over a suit jacket or blazer without pulling across the shoulders or riding up at the waist. The belt adds visual structure and prevents the front from looking shapeless, a common problem with unstructured long coats that have lost their form by mid-morning.
The length and coverage of the Rider make it the more formal of the two options. It is the coat that works over a business suit on a commute, or over a sport coat for dinner in wet weather. The full-coverage front and the knee-length silhouette provide genuine protection rather than token shelter, which matters on a heavy-rain day when most outerwear gives up within the first hour.
The Mac: Understated, Easy, Versatile
The Mac Raincoat takes a quieter approach. Single-breasted and without a belt, the front is clean and uninterrupted. There is less going on in the detail department, which means the coat layers without drawing attention to itself. It does not take over an outfit.
That restraint makes the Mac coat the more versatile of the two for daily use. It works equally well over a tailored trouser and a roll neck as it does over jeans and a casual shirt. The silhouette reads as considered outerwear rather than as a specific formal statement, which is a practical advantage for a coat that will be worn across many different contexts throughout the week.
Which One Is Right for You
The Rider suits someone who wants a mens raincoat trench coat with formal weight: a piece that carries the occasion when worn over tailored clothing without looking like an afterthought. The Mac suits someone who wants something they can reach for every day without thinking hard about dress code. If the wardrobe leans formal, choose the Rider. If the wardrobe is mixed and the coat needs to work across all of it without effort, choose the Mac. In short, it is the difference between a coat that makes a statement and a coat that disappears cleanly into the outfit, and both serve a genuine purpose.
Getting the Fit Right on a Long Coat
Fitting a long coat is harder than fitting a jacket. A jacket that is slightly long in the body is a minor issue that most people live with. A raincoat that sits too long or too short relative to a man's proportions looks visibly wrong and affects how it layers over the clothing underneath. This is the reason so many men settle for a coat that fits through the chest but fails everywhere else.
Both coats here are available with sleeve and body length adjustments at no additional cost. Sleeve length can be adjusted by -6 cm, -3 cm, +3 cm, or +6 cm from the standard. Body length follows the same four-step range. For buyers with precise measurements, a full MTM option allows all dimensions to be specified from scratch.
This level of adjustment is unusual for outerwear available online. Most brands offer a single proportional cut per size, which means a tall man gets a coat that fits through the shoulders but falls short at the knee, and a shorter man gets the reverse. The sleeve-and-body adjustment matrix here addresses the specific proportional problem that makes a long tailored raincoat difficult to buy without a physical fitting.
Sizing covers IT-EU 46 to 56 and US-UK 36 to 46, with a fit guide on the product pages for reference before ordering.
Styling Your Raincoat Across Dress Codes
Over Tailored Clothing
A long waterproof coat worn over a suit or sport coat performs best when the colour is neutral and the silhouette is generous enough not to pull across the jacket shoulders. Both the Rider and Mac are cut with this layering scenario in mind. Earth tones such as camel, beige, and stone sit cleanly over tailored clothing without creating a colour or texture conflict. Navy and charcoal work well for men whose tailoring already carries stronger colour.
The Rider, with its belt and length, signals intention. It reads as part of a deliberate outfit choice. The Mac coat in the same neutral colourway reads as effortless: the coat is present but it is not the focal point.
Over Smart Casual and Weekend Wear
Both silhouettes work well over a roll neck and flannel trousers, a button-down and chinos, or an overshirt paired with straight-leg denim. The key variable when dressing down is body length. A coat that hits mid-thigh over a structured jacket may sit lower over a lighter knitwear layer, which can disrupt proportion. The body length adjustment option is particularly useful here: a slightly shorter body setting keeps the silhouette balanced when the garment underneath is less substantial.
A Note on Colour Choice
Seven colorways are available across both styles. Classic neutrals are the most versatile and the easiest to pair across both tailored and casual contexts. Darker options read slightly more contemporary and suit men whose wardrobes already carry colour. The practical rule is simple: choose the colour that will actually be reached for on rainy days, not the one that looks best in a photograph.
Care and Longevity
Caring for a mens raincoat trench coat built from technical coating fabric is straightforward, but specific. Both coats require dry cleaning at a specialist cleaner only. Do not bleach, tumble dry, or iron at high temperature. The Olmetex technical coating does not respond well to the heat or solvents used in standard home laundering, so hand washing and machine washing should both be avoided.
With appropriate care, a coat built from technical coating fabric of this specification should maintain its waterproofing performance reliably over several years of regular use. Avoid storing the coat compressed or tightly folded for extended periods, as prolonged pressure can affect the fabric structure over time. Hanging on a wide, padded coat hanger in a ventilated space is the preferred storage method.

FAQ
Are these coats fully waterproof or just water-resistant?
The Olmetex fabric is engineered for genuine waterproofing, not a surface DWR treatment. It performs in sustained rain conditions, not just light showers.
What is the difference between the Rider and the Mac?
The Rider is long, belted, and formally inclined. The Mac is single-breasted and understated, easier to wear across mixed dress codes without the coat dominating the outfit.
Can I adjust the sleeve and body length?
Yes. Both dimensions can be adjusted by -6 cm, -3 cm, +3 cm, or +6 cm from standard, or specified fully via the MTM option. No extra cost applies to any adjustment.
How long does delivery take?
Orders are made and dispatched from Shanghai within four weeks, then shipped via DHL. Transit typically takes five to ten days. Free worldwide shipping applies on orders above $100 USD.
How should I care for the coat?
Dry clean only at a specialist cleaner. Do not bleach, tumble dry, or apply high heat when ironing.
What sizing system is used?
Both IT-EU (46-56) and US-UK (36-46) sizes are offered, with a fit guide on each product page to assist with selection before ordering.
Can these coats be worn over a suit jacket?
Yes. Both are cut generously enough to layer over a structured jacket without pulling across the shoulders or restricting movement.
