Fit and Sizing

I typically wear a size 40-inch chest, so I selected a size 40 Merlin jacket to test. The sizing was accurate, with the 40 fittings me comfortably in the chest and shoulders.

The jacket has a tailored fit in the chest and waist, with a generous degree of room to layer underneath. For reference, I am 5’9″ and 180 pounds. The size chart accurately reflects the fit.

The sleeves are pre-curved and allow a full range of motion. I appreciated the accordion panel at the back shoulders, preventing any pulling or restriction when riding.

The Merlin jacket fits true to size based on the sizing chart. It accommodates layering while maintaining a slim profile.

How to Measure

To get the best fit for your Merlin Miller Motorcycle Jacket, measure your chest and waist accurately. Use a flexible tape measure and follow these steps:

• Chest: Measure around the fullest part of your chest, under your armpits, keeping the tape horizontal.
• Waist: Measure around your natural waistline, in line with your navel, keeping the tape horizontal.

Men’s Size Chart

Here’s a detailed size chart for the Merlin Miller Jacket based on chest measurements:

Size	Chest (inches)	Chest (cm)
38	36-38	91-96
40	38-40	96-101
42	40-42	101-106
44	42-44	106-111
46	44-46	111-116
48	46-48	116-121
50	48-50	121-126

Fit Recommendations

• Snug Fit: If you prefer a tighter fit, especially for summer rides when layers aren’t necessary, choose your exact size based on the chart.
• Relaxed Fit: For a more relaxed fit or if you plan to wear layers underneath, consider ordering one size up.

Examples and Tips

In my experience, the Merlin Miller Jacket’s fit is quite snug due to its protective features and premium cowhide leather.

When I measured my chest at 42 inches, the size 42 jacket fit perfectly with a T-shirt but felt tight with a thicker sweater. So, for cooler weather, I opted for a size 44, which allowed for comfortable layering.

Construction and Materials

Merlin constructed this jacket from 1.1mm – 1.3mm brushed cowhide leather. The leather feels thick and durable, with a supple hand and vintage look straight out of the box.

I was concerned the leather would be too heavy for summer riding, but the perforations and venting significantly affect cooling.

Interior details include a polyester mesh lining and a removable 125-gram thermal vest. The mesh material helps wick moisture and allow air to flow through the jacket.

The Merlin jacket is put together with high-quality construction. All of the stitching is even and secure, with no loose threads. The zippers operate smoothly, and the snaps provide a secure closure.

Safety and Protection

For impact protection, the Merlin jacket includes CE-rated D3O armor in the elbows and shoulders. This low-profile armor stays flexible until an impact occurs.

I found the armor comfortable and hardly noticed it during wear. The elbow, shoulder, and back protector pockets make installing or removing the armor easy.

The jacket’s extensive perforations offer abrasion protection without compromising airflow. The leather still provides resistance in a slide while allowing air to permeate through.

The Merlin jacket includes reflective piping on the front, back, and sleeves for visibility. This provides added safety when riding at night.

While not a safety feature, the two hand warmer pockets are generously sized to fit gloves inside. I appreciated having this storage space built into the jacket.

Ventilation and Cooling

The Merlin jacket uses perforated leather along the inner arms, chest, and back to maximize airflow. This allows direct air contact with your skin for superior cooling.

Two zippered chest vents provide direct front torso ventilation when open. I frequently used these vents to allow maximum airflow in the hottest riding conditions.

Along the lower back are two rear exhaust vents. These helped release trapped heat and moisture when riding in warm temperatures.

With the vents and perforations fully open, I was impressed by how well the Merlin jacket flowed air and stayed cool even in near triple-digit heat.

The TFL Cool Tech coating on the leather also helped reduce heat absorption from the sun’s rays. This prevented the jacket from getting overly hot when stopped in traffic.

Versatility and Functionality

A major advantage of the Merlin jacket is its versatility across multiple seasons:

• Wear it as a lightweight summer jacket with the vents open and the thermal liner removed.
• Use it as a cooler spring jacket with the vents closed and the liner installed.
• Layer it under a textile jacket for colder mornings and evenings.

The short connecting zipper allows you to attach Merlin riding pants for a complete leather suit.

Storage options include two zippered hand pockets, a cell phone pocket, and an interior stash pocket. These provide ample room for carrying daily essentials.

Wear and Tear and Durability

High-Quality Materials

The Merlin Miller Motorcycle Jacket is crafted from premium cowhide leather, known for its exceptional durability and resistance to wear and tear. Leather, particularly full-grain leather, is renowned for its longevity.

Full-grain leather retains the natural texture and imperfections of the hide, which contribute to its strength and character. This type of leather can withstand years of heavy use, making it a reliable choice for riders looking for a long-lasting jacket[5].

Abrasion and Tear Resistance

One of the key features of the Merlin Miller Jacket is its high abrasion resistance. Leather is inherently tough and durable, providing excellent protection against road rash in the event of a slide.

The reinforced stitching further enhances its tear resistance, ensuring that it remains intact even under stress. This is crucial for maintaining the jacket’s protective capabilities over time[1][2].

Impact Protection

The jacket comes equipped with D3O armor at the elbows and shoulders, with an option to add a back protector.

D3O is a high-performance impact protection material that is flexible and comfortable during regular use but hardens upon impact to absorb and dissipate energy.

This ensures that the jacket not only withstands wear and tear but also provides reliable protection in the event of an accident.

Weather Resistance

The Merlin Miller Jacket is treated with TFL Cool System technology, which reflects UV rays and keeps the jacket cooler in hot weather. This treatment helps to prevent the leather from drying out and cracking, thereby extending its lifespan.

Additionally, the jacket features a removable thermal liner and a mesh lining, making it adaptable to various weather conditions and reducing the wear caused by extreme temperatures.

Potential Drawbacks

While the Merlin Miller Jacket is built to last, there are a few potential drawbacks to consider. The high-quality materials and advanced features come at a premium price, which might be a concern for budget-conscious riders.

Additionally, the jacket’s snug fit, while providing excellent protection, may not be comfortable for all body types. It’s important to consult the size guide carefully or consider sizing up for a more relaxed fit.

Lastly, while the jacket is versatile, it may not provide sufficient insulation for extremely cold conditions without additional layers.

Prices for the Merlin Miller Jacket fluctuate due to special offers, so I recommend checking Revzilla.com for the latest deals. They offer a price match guarantee, ensuring you won’t find a better price elsewhere.

Maintenance and Care

Care Instructions: Guidelines on How to Maintain the Jacket for Longevity

Cleaning the Leather

I’ve found that regular cleaning is crucial for maintaining the Merlin Miller Jacket’s appearance and durability. Here’s my process:

1. Wipe the jacket with a damp cloth to remove surface dirt.
2. Use a leather cleaner specifically designed for motorcycle gear.
3. Apply the cleaner with a soft cloth, working in small circular motions.
4. Wipe off excess cleaner with a clean, damp cloth.
5. Allow the jacket to air dry at room temperature.

I avoid using harsh chemicals or household cleaners, as these can damage the leather and compromise its protective qualities.

Conditioning the Leather

Leather conditioning is essential to prevent drying and cracking. I follow these steps:

1. Apply a small amount of leather conditioner to a clean cloth.
2. Work the conditioner into the leather using gentle, circular motions.
3. Pay extra attention to high-wear areas like elbows and cuffs.
4. Allow the jacket to absorb the conditioner for a few hours.
5. Wipe off any excess with a clean cloth.

I condition my jacket every 3-4 months, or more frequently if I ride in harsh conditions.

Storing the Jacket

Proper storage extends the jacket’s life. My storage method includes:

1. Hanging the jacket on a wide, padded hanger to maintain its shape.
2. Keeping it in a cool, dry place away from direct sunlight.
3. Using a breathable garment bag if storing for extended periods.

I avoid plastic bags, which can trap moisture and lead to mold growth.

Handling Wet Conditions

If my jacket gets wet, I:

1. Allow it to air dry at room temperature.
2. Avoid using direct heat sources like radiators or hair dryers.
3. Once dry, apply a leather conditioner to restore moisture.

Maintaining Armor and Zippers

To keep the protective features in top condition:

1. I periodically check the D3O armor for any signs of wear or damage.
2. Clean zippers with a soft brush to remove dirt and debris.
3. Apply a small amount of zipper lubricant to ensure smooth operation.

TFL Cool System Maintenance

The TFL heat-resistant treatment doesn’t require special maintenance, but I’m careful not to use products that might compromise its effectiveness.

By following these care instructions, I’ve significantly extended the life of my Merlin Miller Jacket, ensuring it continues to provide comfort and protection ride after ride.
