12oz Canvas Black Karate Pants

Description

Solid black canvas karate pants built for real training

These are straightforward, well-made training pants in 12oz 100% cotton canvas — the same weight and cut that karate and taekwondo practitioners have been training in for decades. If you train in a gi-based art and need reliable black pants that will hold up session after session, these do the job without fuss.

Why 12oz canvas?

Weight matters more than most people realise when it comes to gi pants. Lighter poly-cotton pants are fine for light training, but they tend to feel flimsy during heavy sessions — they shift, bunch, and wear out faster under repeated kicking and grappling stress.

12oz canvas sits in a practical middle ground. It’s heavy enough to hold its shape and resist wear, but not so heavy that it restricts movement. The cotton weave breathes well during extended training, which matters a lot in a Queensland dojo in summer. And because it’s 100% cotton (no synthetic blend), it softens with washing rather than pilling or degrading.

If you want something lighter for competition or fitness training, our 8oz poly-cotton pants are worth a look. But for regular dojo training where durability counts, the 12oz canvas holds its own.

Construction details that matter

The waistband uses an elasticated design with an inner drawstring. This combination is actually more useful than it sounds — the elastic gives you a comfortable baseline fit without constant fiddling, while the drawstring lets you lock everything in place before sparring or pad work so the pants stay put when you’re moving hard.

The traditional cut gives you plenty of room through the hips and thighs. For karate and taekwondo, this is important — chambering kicks, dropping into stances, and moving laterally all require unrestricted movement in the lower body. These aren’t slim-fit training pants; they’re cut with technique in mind.

Who these pants suit

These pants work well across several training contexts:

• Karate: Traditional cut suits kata and kumite training equally well. The black colour is standard across many styles for coloured belts and instructors.
• Taekwondo: A solid option for training when your regular uniform is in the wash, or as a spare pair for intensive training weeks.
• BJJ: Works as a gi pant replacement if you train no-gi as well and want something tougher than board shorts.
• Home training: Comfortable and practical for solo drilling at home — the elastic waist makes them easy to put on and take off.

These are pants only — no jacket is included. If you need a matching gi top, browse our full range.

Sizing these pants correctly

Pacific Sports uses a dual-number sizing system (e.g., 3/160, 4/170) where the first number is a size grade and the second is your approximate height in centimetres. Use your height as the primary guide:

• 3/160 — suits heights around 155–165 cm
• 4/170 — suits heights around 165–175 cm
• 5/180 — suits heights around 175–185 cm
• 6/190 — suits heights around 185–195 cm

The elastic waistband accommodates a reasonable range of waist sizes within each size. If you’re between sizes, the taller size usually works better — shorter pants look and feel wrong during training. Check the size chart images on this page for full measurements.

Care instructions

Canvas gi pants are straightforward to care for, but a couple of habits will extend their life significantly:

• Wash cold or warm (not hot) — hot water can shrink the cotton over time
• Air dry where possible — tumble drying speeds up wear, especially at the seams
• Wash after every training session — canvas holds moisture and odour if left damp

New canvas pants will feel a little stiff at first and may take a few washes to fully soften. That’s normal — it’s a sign the fabric is properly woven rather than pre-softened at the expense of durability.

Frequently Asked Questions

Are these pants suitable for competition?

It depends on your style and organisation. Many karate associations allow black pants for training grades and instructors, but competition rules vary. Check your specific organisation’s uniform requirements before buying for comp use. For standard dojo training, these are completely fine.

Do these pants come with a jacket or belt?

No — these are pants only. No jacket or belt is included. If you need a matching top or a belt, browse the full uniform range on the Pacific Sports website.

Will these shrink after washing?

Like most 100% cotton products, there may be minor shrinkage with the first wash — typically a centimetre or two in length. Washing in cold or warm water (not hot) and air drying will minimise this. If you’re right on the border between sizes, sizing up is usually the safer option.

How do the dual-number sizes work (e.g., 3/160)?

The first number (3, 4, 5, 6) is a sizing grade, and the second number (160, 170, 180, 190) is the approximate height in centimetres the pants are cut for. Use your height as the main guide when selecting your size. The size chart on this page includes full measurements for each size.

Are these pants only for karate, or can I use them for other arts?

The traditional cut works well for karate and taekwondo, but they’re also a practical choice for BJJ gi training, jiu-jitsu, and general home training. The black canvas is a bit more versatile than a white gi pant if you train across multiple styles.

How long do 12oz canvas pants typically last?

With normal dojo training (a few sessions per week) and proper washing and air drying, a good pair of 12oz canvas pants should last several years. Canvas is more durable than lighter poly-cotton blends, so these are worth the slightly higher price if you train regularly.
