There are two main types of crashpad on the market: folding crashpads and wraparound crashpads.
Foldable crashpads generally divide into two or three segments and fold like books or accordions. This type of design facilitates transport and storage, making the crashpad compact when folded. However, it's crucial to check the continuity of the padding at the folds to avoid any less protected areas that could become a weak point during a fall.
Wrap-around crashpads, often referred to as "taco-style" because they fold in one piece without rigid hinges, offer a uniform landing surface with no hard points. They are particularly appreciated for their ability to adapt to irregular surfaces. Nonetheless, their non-folding shape can make them more cumbersome to transport.
The choice of padding material is crucial to the effectiveness of a crashpad. Commonly used materials are open-cell and closed-cell foam. Top-of-the-range crashpads often use a combination of both: a layer of closed-cell foam on top for even impact distribution, and a layer of open-cell foam underneath for better shock absorption.
The crashpad's outer cover must be abrasion and tear resistant, yet flexible enough to be bent repeatedly. Materials such as ballistic nylon are frequently used for their robustness. It's also essential that the fabric is treated to resist water and moisture, which extends the life of the mattress in outdoor environments.
A good crashpad should be easy to carry. Adjustable shoulder strap systems, similar to those of a backpack, are essential for optimum comfort on long approaches. Some models also offer additional handles or straps to facilitate rapid movement over short distances.
The crashpad's fastening mechanisms must ensure that it remains closed during transport. Velcro and buckles are the most common options. It's crucial that these elements are both robust and easy to handle, even when wearing gloves.
Some crashpads are designed to attach to each other, creating a larger, safer fall surface. This feature can be particularly useful during bouldering sessions where several pads may be needed to adequately cover the fall zone.
Choosing a crashpad for climbing should not be taken lightly. Safety, comfort and performance all depend on it. It's essential to choose a model adapted to your own needs, taking into account the type of climbing practiced, the terrain frequented, and the frequency of sessions. Investing in a good crashpad will ensure years of safe and enjoyable practice in the fascinating world of bouldering.
Remember to always check the condition of your equipment before each use, and replace any that show signs of significant wear. Climbing safety is highly dependent on the quality and maintenance of the equipment you use. Happy climbing!
