Sizing for harnesses, helmets, apparel, gloves, packs and footwear. All values are body measurements — not garment dimensions — shown in inches with centimeters below.
Men's / Unisex Harness Fit Guide
Measure the waist where you wear your harness, and around the fullest part of your legs.

Women's Harness Fit Guide
Women's harnesses use a women's specific rise. Fit by waist and leg measurements, not by apparel size.
| Size | Waistin / cm | Legin / cm |
|---|---|---|
| XXS | 24–2761–69 | 17–2143–53 |
| XS | 26–2966–74 | 18–2046–51 |

Kids' Harness Fit Guide
The Kids' Momentum harness is a one-size, highly adjustable sit harness for growing climbers.
| Size | Waistin / cm | Legin / cm |
|---|---|---|
| One Size | 22–2856–71 | 19–2348–58 |
Full Body option for small children
The Momentum Kids Full Body harness is one size and fits hips of roughly 35–65 cm with a maximum thigh circumference of 51 cm. The high tie-in point keeps small climbers upright.
Adjustability does the rest
Speed buckles on the waistbelt and trakFIT leg-loop adjusters cover a wide range within each size. If you fall between two sizes, pick the size whose waist range contains your measurement.
Layering matters
If you climb in winter layers, measure over the clothing you plan to wear, or move up one size.
Safety gear returns
Harnesses and all load-bearing equipment should be inspected before first use. Once worn, life-safety gear generally cannot be returned for sizing reasons — measure carefully.
Helmet Size Chart
Most models share one size range. The Half Dome runs a range of its own — check it separately.
| Size | Head Circumferencein / cm |
|---|---|
| S/M | 21–2353–59 |
| M/L | 23–2558–63 |
| Size | Head Circumferencein / cm |
|---|---|
| S/M | 19–22.548–57 |
| M/L | 22–2455–61.5 |
How to measure
Wrap a soft tape around the largest part of your head — about one inch (2.5 cm) above the eyebrows — keeping it level above the ears.
Between two sizes?
The ranges overlap. Choose the size that sits stable without pressure points; it must not slip when you shake your head.
Beanies underneath
A thin beanie can be worn if the helmet still adjusts correctly and stays positioned. Avoid bulky layers.
Fit check
Position the helmet level, then adjust the rear retention system and chin strap. The helmet should move with your head, not independently.

How to Measure
Use a soft measuring tape, keep it level and snug — not tight — and measure over the clothing you plan to wear.
Neck
Around the fullest part of the neck, at the base.
Chest / Bust
Around the chest just under the arms and across the shoulder blades.
Sleeve / Arm Length
From the center back of the neck, across the shoulder, and down the arm to the wrist.
Waist
Around the narrowest part of the waist. For harnesses, measure where you actually wear the waistbelt.
Hip
Around the widest point of the hips.
Inseam
From the crotch to the floor, on the inside of the leg, while standing straight.
Leg (harness)
Around the fullest part of the thigh or leg where the leg loop will sit.
Head (helmets)
Around the largest part of the head, about one inch (2.5 cm) above the eyebrows.
Measure both sides
Where a range applies (waist and leg for harnesses), both measurements must fall inside the same size for the best fit.
End of day
Measure at the end of the day when your body is at its largest — especially feet and hands.
Between sizes
For apparel, size up to accommodate midlayers. For safety gear, choose the size whose range contains your measurement and adjust from there.
Two-year warranty
All products are covered by a two-year warranty against defects in materials and workmanship.
All sizing refers to body measurements, not garment or gear dimensions. Values are approximate and provided for reference only.
