Rashguard vs No-Gi: What to Wear for Grappling Training

Introduction

Whether you're new to grappling or transitioning between gi and no-gi training, understanding what to wear can be confusing. This guide breaks down the differences between rashguard and no-gi training attire, when to wear each, and how to choose the right gear for your training style.

What is No-Gi Training?

No-gi grappling refers to Brazilian Jiu-Jitsu, submission grappling, or MMA training without the traditional gi. Instead of the heavy cotton uniform, practitioners wear form-fitting athletic wear that allows freedom of movement while preventing fabric grabs.

No-gi training emphasizes different techniques since there are no lapels, sleeves, or pants to grip. The pace is typically faster, and the style translates more directly to MMA and self-defense scenarios.

Essential No-Gi Attire: The Rashguard

A rashguard is a tight-fitting, moisture-wicking shirt designed specifically for grappling. Originally developed for surfing, rashguards have become the standard for no-gi training.

Key features of quality rashguards:

• Compression fit that stays in place during rolling
• Moisture-wicking fabric to keep you dry and comfortable
• Flatlock stitching to prevent chafing and irritation
• Antimicrobial treatment to reduce odour and bacteria
• Reinforced seams at stress points

Long sleeve vs short sleeve: Long sleeve rashguards offer more skin protection and are preferred for competition. Short sleeve options provide better cooling for intense training sessions.

No-Gi Shorts: What to Look For

No-gi shorts (also called fight shorts or grappling shorts) are purpose-built for ground fighting:

• No pockets or zippers: These can catch fingers or cause injuries
• Stretchy waistband: Allows full range of motion for guard work and scrambles
• Split or stretch panels: Enables deep squats and high kicks without restriction
• Appropriate length: Typically mid-thigh to just above the knee
• Secure closure: Velcro and drawstring combination prevents shorts from shifting

Spats: The No-Gi Alternative to Gi Pants

Spats (compression pants or grappling tights) are increasingly popular for no-gi training:

Benefits of wearing spats:

• Full leg protection against mat burn and skin infections
• Compression support for muscles during intense training
• Moisture management keeps you dry
• Required for some competitions and gyms
• Prevents skin-to-skin contact

Many grapplers wear spats under shorts for maximum protection and coverage.

Gi Training vs No-Gi Training: Key Differences

Technique differences:

• Gi training emphasizes grips on collar, sleeves, and pants
• No-gi focuses on underhooks, overhooks, and body control
• Gi allows for more methodical, grip-based attacks
• No-gi tends to be faster-paced with more scrambles

Physical demands:

• Gi training can be more grip-intensive, building forearm strength
• No-gi requires more cardiovascular endurance due to faster pace
• Both styles complement each other and improve overall grappling

What to Wear: Gym Etiquette and Requirements

Always check your gym's specific requirements, but general guidelines include:

For no-gi classes:

• Rashguard (long or short sleeve)
• Grappling shorts or spats (or both)
• No t-shirts, cotton clothing, or loose fabrics
• No jewelry, watches, or hard accessories

For gi classes:

• Clean, properly fitted gi
• Many practitioners wear a rashguard under the gi for hygiene
• Some gyms require specific gi colors

Choosing Your First Rashguard and No-Gi Gear

When selecting your first no-gi setup, prioritize:

• Fit: Compression fit that doesn't restrict movement
• Quality construction: Flatlock seams and reinforced stitching
• Moisture management: Look for quick-dry, antimicrobial fabrics
• Durability: Invest in quality gear that will withstand regular training
• Appropriate coverage: Ensure rashguards are long enough to stay tucked during rolling

Caring for Your No-Gi Gear

Rashguards and spats require similar care to gis:

• Wash in cold water after every training session
• Air dry to prevent shrinkage and maintain elasticity
• Avoid fabric softener which damages moisture-wicking properties
• Never leave damp gear in your bag

Conclusion

Whether you're training gi or no-gi, wearing the proper attire enhances your performance, protects your skin, and shows respect for your training partners. A quality rashguard and appropriate shorts or spats are essential investments for any serious grappler. Both training styles offer unique benefits, and having the right gear for each ensures you're prepared for any class or competition.
