Why Choosing the Right BJJ Gi Matters
In Brazilian Jiu-Jitsu (BJJ), your gi is more than just clothing—it's your uniform, your tool, and sometimes even your opponent. A well-chosen gi enhances grip fighting, movement, and durability during intense rolls. Whether you're a white belt starting out or a black belt competing, finding the perfect fit can transform your training. This guide breaks down key factors like weave types, weight, sizing, colors, and maintenance to help you make an informed decision.
Understanding Gi Weaves: Pearl, Gold, and Beyond
The weave determines your gi's feel, strength, and performance. Here's a breakdown:
- Pearl Weave: The gold standard for most practitioners. Made with a balanced thread count (usually 350-450 GSM), it offers a smooth surface ideal for competition and training. It's forgiving for gi chokes and provides excellent breathability without being too stiff.
- Gold Weave: Hyperfly's signature innovation, blending pearl and honeycombed structures. At around 450 GSM, it delivers superior strength and a unique texture that improves grip retention. Perfect for no-gi transitions or those who want a gi that grips back.
- Honeycomb Weave: Tighter and more rigid, often 550+ GSM. Great for heavyweight competitors needing maximum durability, but it can feel heavy for everyday training.
- Lightweight Weaves (e.g., 350 GSM): Ideal for hot climates or high-intensity sessions. Hyperfly's Ultra Light models prioritize speed and ventilation.
Choose based on your style: technical guard players might prefer pearl for fluidity, while pressure passers opt for gold or honeycomb for control.
Gi Weight and Cut: Balancing Comfort and Performance
Gi weight, measured in GSM (grams per square meter), affects everything from drying time to roll feel:
| Weight Category | GSM Range | Best For |
|-----------------|-----------|----------|
| Lightweight | 300-400 | Competition, hot gyms, speed-focused training |
| Midweight | 400-500 | All-around training and competition |
| Heavyweight | 500+ | Strength training, durability in tough environments |
Hyperfly gis excel in mid-to-heavy weights, with models like the Alpha Gold at 450 GSM striking a perfect balance.
Cut Styles:
- Classic Fit: Roomier pants and jacket for traditionalists. Allows for expansive movements in open guard.
- Athletic Fit: Tailored for modern BJJ—shorter sleeves, reinforced knees, and a snugger pant leg to reduce drag.
- Competition Cut: Ultra-light with minimal fabric, IBJJF-compliant for tournaments.
Pro Tip: Test mobility by attempting a basic guard pass in-store or visualize your go-to techniques.
Mastering BJJ Gi Sizing
Sizing is crucial—too tight restricts breathing, too loose hinders grips. Hyperfly uses A0-A6 for men (A1 smallest, A6 largest) and F1-F4 for women, based on height and weight.
Men's Sizing Chart Example:
| Size | Height | Weight | Jacket Length | Pant Length |
|------|--------|--------|---------------|-------------|
| A0 | 5'4"-5'6" | 110-130 lbs | 27" | 34" |
| A1 | 5'6"-5'8" | 130-155 lbs | 28" | 35" |
| A2 | 5'8"-5'10"| 155-180 lbs | 29" | 36" |
| A3 | 5'10"-6'0"| 180-210 lbs | 30" | 37" |
| A4 | 6'0"-6'2" | 210-240 lbs | 31" | 38" |
| A5 | 6'2"-6'4" | 240+ lbs | 32" | 39" |
| A6 | 6'4"+ | 260+ lbs | 33" | 40" |
Women's Sizing follows similar logic but with adjusted proportions for broader hips and shorter torsos.
Sizing Tips:
- Measure chest, waist, and inseam accurately.
- BJJ gis shrink 1-3% after first wash—size up if between sizes.
- Try on if possible: sleeves should reach mid-forearm, pants cuff at ankles.
For Apollo MMA customers, we recommend cross-referencing with your weight class in MMA or wrestling for a versatile fit.
Colors, Patterns, and IBJJF Compliance
BJJ gis come in traditional white, black, blue, and navy, but patterns add flair:
- Solids: White for purity, black for stealthy grips.
- Custom Prints: Hyperfly's artist collaborations feature bold graphics without sacrificing quality.
IBJJF Rules: White, blue, or black only for tournaments (no patches on pants). Always check latest regs.
Relevance to Other Sports: While BJJ-specific, a good gi works for judo or submission wrestling.
Key Features to Look For
- Reinforcements: Double-layered knees, ripstop pants for tear resistance.
- Stitching: 8-10 stitches per inch minimum; Hyperfly uses 10-panel construction for flexibility.
- Embroidery: Subtle logos that don't interfere with grips.
- Pants Drawstring: Rounded for comfort, triple-reinforced.
Maintenance: Keep Your Gi Tournament-Ready
Proper care extends life:
1. Rinse immediately after use to remove sweat/chlorine.
2. Wash cold with gi-specific detergent (no bleach).
3. Air dry—avoid dryers to prevent shrinkage.
4. Store flat or hung.
Pro Fighters' Hack: Soak in vinegar solution monthly to kill bacteria and soften fabric.
