Best BJJ Gi for Academy – Our Picks

The weave of your gi’s jacket affects weight, durability, and feel. Pearl weave is the most common today-it’s lightweight, strong, and dries fast. Gold weave is heavier and softer, great for durability but can soak up sweat like a sponge. Single weave is old-school and ultra-light, often used in cheap gis, but it rips easily. For academy training, pearl weave hits the sweet spot.

Gi weight is measured in GSM (grams per square meter). A lightweight gi (300-400 GSM) is cooler and easier to move in, but might not last as long. A midweight (400-500 GSM) offers a solid balance. A heavyweight (500+ GSM) is tough as nails but can feel like you’re wearing a carpet. For most academies, a lightweight or midweight gi is ideal-you’ll train more comfortably without sacrificing too much durability.

Every brand sizes differently. A size A2 in Fuji can be an A3 in Elite. Always check the brand’s specific size chart and measure yourself. Don’t rely on your height alone-weight and body shape matter. Gis will shrink slightly even if preshrunk, so if you’re between sizes, go larger. A gi that’s too tight restricts movement; too baggy gives opponents handles.

Most modern gis are preshrunk, meaning they shouldn’t change much after washing. But “preshrunk” is often a marketing term-expect up to 3% shrinkage regardless. Hand-wash in cold and hang dry to minimize it. If a gi isn’t labeled preshrunk, prepare for a size or two drop. Budget gis especially may shrink more.

Standard cotton pants are breathable but soak sweat. Ripstop pants are lighter, wick moisture, and resist tearing-they’re becoming the norm. Canvas pants are heavy and durable, but uncomfortable in hot gyms. For academy, ripstop pants are a smart upgrade; they dry faster and feel less soggy by the end of class.

Thick, stiff collars are harder for opponents to grip, but they can feel like a cheese grater on your neck. EVA foam or rubber cores in collars maintain shape without the discomfort. Reinforced cuffs prevent fraying and snaps. Look for extra stitching at stress points-it’s a sign of a gi built to last.

If you plan to compete, your gi must meet IBJJF regulations for color and fit. White, royal blue, and black are standard; other colors may not be allowed. Check with your academy-some schools have strict gi policies. Even if you don’t compete, an IBJJF-approved gi usually means it’s well-made.

Your gi is a bacteria magnet. Wash it after every training session in cold water-hot water causes shrinkage. Use white vinegar occasionally to kill odors. Avoid heavy detergents and bleach. Air drying is best, but if you must use a dryer, do so on low heat. A clean gi is a sign of respect to your training partners.
