With their vibrant artwork and free-flowing comfort, it's easy to get swept up in the aesthetic beauty of Rush Hawaiian shirts. But their enduring popularity also comes down to what lies underneath - the quality of materials and fabric compositions that allow the wearer to feel as good as they look.

From lightweight, breathable fabrics perfect for beachy vibes to premium options that balance luxury with durability, Rush utilizes fabrics that move with you while showcasing the iconic island prints.

Let's explore exactly what goes into making these statement-makers, from fabric terminology to specific material options and blends. Read on for an inside look into the fibers fueling the Rush Hawaiian shirt phenomenon.

Key Rush Hawaiian Shirt Fabrics and Blends

Cotton
From off-duty weekend wear to breezy tropical vacations, cotton ranks among the most ubiquitous fabrics found in Rush’s Hawaiian shirt collections. With natural fibers that feel smooth against the skin and offer breathability, cotton stands out for its:

• Comfort
• Lightweight feel
• Casual drape
• Affordability
• Easy care

Rush often utilizes pima cotton or superior long staple cottons interwoven with spandex or polyester for added stretch and shape retention.

Rayon
A semi-synthetic fabric blending natural and man-made fibers, rayon offers lightweight breathability similar to cotton but with increased drape and flow. Rush shirts crafted from rayon have a softer handfeel and Often utilize:

• Viscose rayon: Smooth with a cool, crisp feel
• Modal: Extremely soft with a velvety texture
• Lyocell: Flowy drape that resists wrinkles

Blends of rayon and spandex, polyester, or cotton are also common, uniting optimal comfort and functionality.

Silk
For ultimate luxury, Rush also crafts select Hawaiian shirts from 100% silk or silk blends. Made from delicate yet durable natural protein fibers, silk offers an ultra-soft feel with:

• Lightweight, billowy drape
• Bright, saturated colors
• High luster sheen
• Thermo-regulating qualities
• Wrinkle resistance

While expensive as a stand-alone material, when blended with cotton or rayon, silk adds a touch of upscale quality at more reasonable pricing.

Polyester
While less common than natural fibers, performance Hawaiian shirts from Rush may also incorporate polyester, typically blended with cotton. Benefits include:

• Wrinkle resistance
• Retention of shape and color
• Durability
• Affordability
• Easy care

By blending cotton’s breathable comfort with polyester’s functionality, these shirts strike an optimal balance of comfort, performance, and style.

Characteristics to Consider Based on Fabric Composition

When investing in a Rush Hawaiian shirt, the specific fabric impacts the overall look, feel and functionality. Consider the following based on your personal preferences and intended uses:

Airflow: Lightweight cotton and rayon or blends allow maximum airflow for comfort in warm weather, while silk traps heat efficiently.
Drape/Structure: Rayon and silk offer free-flowing drape, while cotton provides more structure. Blends create balance.
Texture: Soft, smooth textures come from pima cotton, modal, and silk where high-end extra long staple cotton, linen, and poly blends offer crisp structure.
Sheen: Silk and rayon fibers naturally reflect light for a subtle sheen, while matt cotton and blends have a classic matte finish.
Maintenance: Natural fibers like cotton and silk require gentler cleaning methods compared to polyester blends that tolerate machine washing.
Affordability: Cotton/poly blends offer the best value for money, while pure silk sits at the highest price point.

Anticipating these performance factors based on fabric content helps match the right Rush shirt with your wardrobe needs and care routine.
