Climbing Magnesium

Climbing Magnesium: Complete Guide

Magnesium is an essential product for climbing. It improves grip by absorbing sweat and reducing hand slippage. It is used in bouldering, on cliffs, and in gyms.

What is magnesium?

Magnesium is generally magnesium carbonate. It comes in powder (ball or bucket) or liquid form (diluted resin). Both formats aim for the same goal: to improve friction between the skin and the rock or hold.

Powder magnesium vs liquid magnesium

Powder magnesium:

• Advantages: quick absorption, easy to sprinkle, economical and versatile.
• Disadvantages: dust generated in the gym, dirties holds and sometimes requires blowing after movements.

Liquid magnesium:

• Advantages: clean and durable application, reduces dust, better grip on the skin during multiple movements.
• Disadvantages: more expensive, requires drying before climbing, less practical for quick touch-ups mid-route.

Which type to choose for climbing?

For bouldering or short sessions where you want to touch up often, powder remains the reference. For long routes, competitions in clean gyms, or if you want to limit dust, liquid magnesium is ideal. Many climbers combine both: liquid for the base, powder for finishing touches.

Associated equipment: magnesium bags and more

A good magnesium bag allows easy access to magnesium without spilling it everywhere. Choose a bag with a closure and a dust-proof lining. Models with a cord and loop to attach to the harness or waist are practical. Also consider magnesium gloves and cloths for holds.

Finally, for carabiners and protections, the Black Diamond climbing and mountaineering gear covers many needs.

How to choose the right magnesium bag?

• Size: prefer a format that holds the desired quantity without being too bulky.
• Closure: zip or tight cord to limit leaks.
• Lining: dust-proof or velcro fabric for better adherence to magnesium.
• Attachment: loop or carabiner to attach to the harness or waist.

A good bag extends the life of your magnesium and reduces dust dispersion in the gym.

Usage tips

• Apply a small amount, rub to distribute. Too much magnesium can hinder the feeling of friction.
• If using liquid, let dry for 10–30 seconds depending on the amount applied.
• Respect the rules of gyms: some limit or prohibit powder magnesium.

FAQ

Does magnesium damage the skin?
No, it generally dries the skin but is not corrosive. Moisturize after the session to avoid cracks.

Is liquid magnesium better than powder?
It reduces dust and lasts longer, but powder remains more practical for quick touch-ups.

How much magnesium to take on a long route?
A small vial of liquid + a bit of powder for touch-ups is often sufficient.

Where to buy?
Choose specialized retailers that offer tested climbing products and tailored advice. Packs combining magnesium and magnesium bags remain a good investment.

In summary: choose magnesium according to your practice (powder for touch-ups, liquid for cleanliness and grip), equip yourself with a good bag, and prioritize reliable gear for safe climbing.
