Mammut Carry-On Climbing

Best uses

Most climbing harnesses are versatile enough for indoor climbing or outdoor multi-pitch routes, while some are more specialized for mountaineering or ice climbing.

• Sport or indoor climbing: Stripped down for fast travel and feature minimal gear loops.
• Trad climbing: More gear loops since climbers place their own protection. Comfort and padding are key, as you may spend hours on a route or hanging in your harness.
• Mountaineering: Designed for long approaches and all-season versatility
• Ice climbing: Designed to perform in winter conditions

Key features:

• Padded waist: Thicker padding or a broader surface area helps distributes pressure
• Adjustable leg loops: Fit different body types and clothing layers
• Gear loops: Typically two to five loops for racking gear
• Droppable leg loops: Leg loops unclip at the back for easier bathroom breaks

Women-specific harnesses

• These typically feature a higher rise, a larger leg-to-waist ratio and a shaped waistbelt
• Choose a women-specific harness if it better matches your body type.

Locking vs. Non-locking 

Locking carabiners: Gates lock to prevent accidental openings during falls; essential for belaying or critical protection placements

• Screw-lock: Requires manual twisting to close
• Auto-locking (twist lock): Automatically locks when the gate closes

Non-locking carabiners: Lighter, quicker to clip or unclip but can accidentally open; ideal for racking gear or for quickdraws

Carabiner shape

• D shape: Strongest shape, excellent for most kinds of climbing
• Asymmetric D: Lighter than D shape with a larger gate for easy clipping; use for belaying, rappelling, general climbing  
• Pear shape: Designed for belaying, rappelling and anchor points; heavier and more expensive
• Oval shape: Smaller gate opening, affordable but not as strong or light as others; ideal for aid climbing or racking trad gear

Gate Types 

• Straight-gate: Durable, easy to use; common for clipping gear to harnesses
• Bent-gate: Makes rope clipping easier; generally used for quickdraws  
• Wire-gate: Lightweight, less likely to freeze or vibrate open during a fall
• Locking: Most secure; essential for anchors or belaying

What is an avalanche transceiver?

• If you recreate in snowy backcountry terrain, an avalanche transceiver is an essential safety device—along with a probe and shovel
• Transceivers help you locate someone buried in an avalanche and it helps rescuers find you if you’re buried

What features should I look for?

• Analog or digital: Most modern transceivers are digital; some are both digital and analog
• Multiple burials: Allows searchers to detect more than one buried person; most offer this feature
• Marking function: Lets a searcher to mark the location of a buried person so they can search for another one
• Display screen: Displays direction and distance to a buried person
• Range: Listed in meters (typically 40-70m), the circular range at which one transceiver can detect another
