3XL 119–124 52 65 76

How to Measure for Jackets:

  • Chest: Measure around the fullest part of your chest, under your armpits, keeping the tape horizontal.
  • Shoulder: Measure from the end of one shoulder (at the top of the arm) across to the other shoulder.
  • Sleeve: Measure from the shoulder seam down to your wrist.
  • Length: Measure from the base of the neck (at the back) down to the desired hemline.

Tip: If you plan to wear multiple layers underneath your jacket, or if you are between sizes, consider choosing the larger size for a more comfortable fit.

Note: This is a general guide. Specific product pages may contain more detailed sizing information for individual styles. Measurements are for the garment itself.

PANTS SIZE GUIDE (AU Standards)

Men's Pants (AU/US Sizing)

MEN'S PANTS - BODY MEASUREMENTS (AU/US Inches)
Waist Size (Inches) Waist (cm approx.) Typical Inseam (Inches) Typical Inseam (cm approx.) AU Alpha Size (Equiv.)
28 ~71 30-32 ~76-81 XS
30 ~76 30-32 ~76-81 S
32 ~81 32 ~81 M
34 ~86 32-34 ~81-86 L
36 ~91 32-34 ~81-86 XL
38 ~96 32-34 ~81-86 XXL
40 ~101 32-34 ~81-86 3XL

➡️ Men's pants are often sized by Waist (in inches) and sometimes Inseam (length, also in inches). For example, "32/32" = 32-inch waist / 32-inch inseam. Many brands offer Short (S ~30"), Regular (R ~32"), and Long (L ~34") inseam options.

Women's Pants (AU Sizing)

WOMEN'S PANTS - BODY MEASUREMENTS (AU)
AU Size Waist (cm) Waist (in) Hips (cm) Hips (in) Typical Inseam (cm) Typical Inseam (in)
6 60-64 23.5-25 85-89 33.5-35 ~78 ~30.5
8 65-69 25.5-27 90-94 35.5-37 ~79 ~31
10 70-74 27.5-29 95-99 37.5-39 ~80 ~31.5
12 75-79 29.5-31 100-104 39.5-41 ~81 ~32
14 80-84 31.5-33 105-109 41.5-43 ~81 ~32
16 85-89 33.5-35 110-114 43.5-45 ~82 ~32.5
18 90-95 35.5-37.5 115-119 45.5-47 ~82 ~32.5

➡️ "Typical Inseam" is an average; actual inseam can vary by style (e.g., ankle, regular, tall). Always check product details!

Finding the right pant fit is key! Below are our general sizing guides for men's and women's pants, following Australian conventions. Remember that fit can vary slightly by style and fabric.

Important: For the most accurate sizing, we strongly recommend checking the specific measurements table on each individual pant product page if available, as cuts and materials can vary significantly.

How to Measure for Pants:

  • Waist: Measure around your natural waistline (usually the narrowest part for women, where pants sit for men). Keep the tape comfortably loose.
  • Hips (Women's): Measure around the fullest part of your hips and bottom, keeping the tape level.
  • Inseam: Measure from the crotch seam (top of your inner thigh) down to your desired hem length (usually ankle bone). It's best to measure a pair of existing well-fitting pants: lay them flat and measure from crotch seam to hem.
  • Rise: Consider the rise (low, mid, high) mentioned on product pages, as this affects where the waistband sits and the overall fit.

Tip: If you're between sizes, consider the desired fit. For a tighter fit, size down; for looser, size up. Check fabric description for stretch (elastane/spandex).

ADULT HAT SIZE GUIDE

Find your perfect hat size by measuring your head circumference. Our sizes are provided in both centimeters (cm) and inches (in).

HAT SIZES - HEAD CIRCUMFERENCE
Alpha Size Centimeters (cm) Inches (approx.)
XS 53-54 ~21 1/8
S 55-56 ~21 5/8
M 57-58 ~22 1/2
L 59-60 ~23 1/4
XL 61-62 ~24
XXL 63-64 ~24 3/4

How to Measure Your Head for a Hat:

  1. Take a soft measuring tape (or a piece of string you can measure later).
  2. Wrap it around your head, horizontally, across the middle of your forehead and just above your ears – where a hat would comfortably sit.
  3. Ensure the tape is snug but not too tight. Read the measurement in centimeters.
  4. Compare to the chart. If you're between sizes, choose the larger one for comfort. You can often add hat sizer inserts for a more custom fit if needed.

How to measure your head for a hat

Note: Hat sizing can vary slightly between styles (e.g., beanies vs. structured hats). This guide is for general reference.

BOOT SIZE GUIDE (Unisex)

Our unisex boots are generally based on AU/UK Men's sizing. The most reliable way to find your fit is by measuring your foot length in centimeters (cm).

UNISEX BOOT SIZES (Based on AU/UK Men's Scale)
AU/UK Men's US Men's (Approx.) AU/US Women's (Order this AU/UK Men's size) EUR (Approx.) Foot Length (cm)
5 6 Approx. 7 - 7.5 38 23.5 - 24
6 7 Approx. 8 - 8.5 39 24.5 - 25
7 8 Approx. 9 - 9.5 40-41 25.5 - 26
8 9 Approx. 10 - 10.5 42 26.5 - 27
9 10 Approx. 11 - 11.5 43 27.5 - 28
10 11 Approx. 12 - 12.5 44-45 28.5 - 29
11 12 N/A or Special Order 46 29.5 - 30
12 13 N/A or Special Order 47 30.5 - 31
13 14 N/A or Special Order 48 31.5 - 32

For Women ordering unisex boots: As a general rule, you will need to go down 1.5 to 2 sizes from your standard AU/US Women's shoe size. For example, if you are a Women's AU/US 8.5, you would likely try an AU/UK Men's size 6 or 7. Always prioritise your foot length in CM for the best accuracy.

How to Measure Your Foot Length for Boots:

  1. Place a piece of paper flat on the floor, with one edge against a wall.
  2. Stand on the paper with your heel firmly against the wall. Wear the type of socks you'd typically wear with boots.
  3. Mark the longest part of your foot (usually your big toe or second toe) on the paper.
  4. Measure the distance from the edge of the paper (that was against the wall) to your mark in centimeters (cm).
  5. Repeat for your other foot, as they may differ. Use the measurement of your larger foot.
  6. Compare this CM measurement to the "Foot Length (cm)" column in our chart.

(Consider adding a simple diagram here showing foot measurement)

Further Notes:
- If you are between sizes or plan to wear very thick socks, consider sizing up.
- Boot fit can also depend on width and style. This guide is for length.
