My thumb wrapped around a small edge on Crimping Matters (V10), a 20-move series of granite crimps at Guanella Pass, just outside of Georgetown, Colorado. As I exited the cave, my elbows pointed skyward and I entered the upper crux: a cross to one more crimp. The landing’s 30-degree slope and jagged features made it difficult to spot so the pad setup needed to protect me. I forgot about the landing as my fingers hit the hold. I tried to pull through the last move but my hand opened. I was off. I slid down the seven pads we had placed on the slanted granite below. Luckily, our variety of pads, the small ones filling holes and the big ones protecting the slabs and flatter sections, covered the talus pit landing and I fell unscathed. Had my friends and I lacked the proper pads, I could’ve easily broken an ankle and ruined a climbing day, or even my season.
Climbers have long been flattening out landings. When Ron Kauk did the first ascent of Thriller (V10) in Yosemite, he placed palates under the landing, then nicked some employee mattresses. Other early pad iterations included sofa cushions wrapped in duct tape and creatively placed wooden pallets. Up until the late ’80s no one bouldered with a pad.
“Before pads came out you had to kind of be a masochist to be a boulderer,” said Hueco Tanks legend John “Verm” Sherman, who was also responsible for the V-scale grading system. In 1992, Verm and his friend Bruce Pottenger, the head of the Kinnaloa crew who made t-shirts and chalk bags, joined forces to sell the first commercial crashpad: the Sketch Pad. The two had developed it for personal use, but then realized they had the tools to bring it to market.
Since the development of the Sketch Pad, subsequent models have enlarged the original design. Like pads today, the Sketch Pad had a nylon sleeve with pack straps and two densities of foam. It was made out of cloth material with a carpet area to wipe your feet. The pad measured 2.5′ by 3.5′ with around 2″ of foam. “By today’s standards, those things looked like cocktail napkins,” said Sherman.
Now, over 50 manufacturers worldwide provide pads with advanced harness systems, room for gear, and high-tech foam setups for maximum protection. “A real revolution in my eyes was when we started padding stuff because that opened terrain like crazy,” said Sherman. “The pad changed everything. It brought bouldering to the masses.”
The primary purpose of a crashpad is to add a foam layer between the climber and the ground, to lessen the impact of a bouldering fall. A standard crashpad has various different attributes, including the type of folding system, materials, foam types, size, and special features. Crashpads are used on all sorts of terrain; some pads are better for flat ground while others are better for uneven, rocky landings. The construction of each pad is setup with certain benefits in mind, which makes each pad unique.
Folding systems affect the cushion of the foam, the carrying system, and a pad’s closed size. Depending on the folding system, a pad can be better or worse for a particular landing. From my experience, the fold style impacts my ease of transportation the most. Being able to sufficiently carry the gear that I need in a condensed space is crucial for the long approaches of Rocky Mountain National Park (RMNP).
The taco is one continuous piece of foldable soft foam. Although they are generally softer pads, they maintain the same level of cushioning throughout the whole pad, including the fold point. The taco-style fold works best on uneven, rocky landings and less so for flat landings. For example, the taco shape folds nicely over the jumble of roots at the base of Sloppy Poppy in Squamish, BC, yet struggles to lie flat at the base of Iron Man Traverse in Bishop, CA. While tacos have a fair amount of room for gear, they are difficult to store because they don’t lie flat. If you have a taco, be sure to store it open to preserve the foam.

Tri-fold pads can act as stand-alone pads because of their large size, yet are hinged in two areas, allowing for some variability in landing zones. The tri-fold system allows large pads to be folded small when closed, making it is easier to carry them or store in a car or closet. Not to mention, they make for a good night’s sleep in the back of a car. While you cannot carry much gear in them, their condensed size makes the large pad easy to carry. The multi-hinge design also allows you to add significant height to a landing when the pad is closed, allowing you to even out sections or use the pad as a step stool to project hard moves a few feet off the ground.
In a hinge pad, a piece of nylon material holds two large pieces of foam together. These pads easily carry as a backpack or as a briefcase, provided they have a side handle. Hinge pads lay the flattest of any type of pad, making them ideal for flat landings. They also fold up tightly and double as spacious gear carriers. On the downside, you could land on something sharp due to the lack of foam in the hinged area. As a result, hinged pads perform worse on uneven terrain or rocky landings. These pads, however, are relatively common and a great addition to any multi-pad landing area with flat space.
Less common, but as seen in the Mad Rock R3, are pads with a baffled designed, where partial hinges, creased to half the thickness of the pad, separate several recycled foam stuffed baffles. The shredded, recycled foam molds to rocky terrain, arguably better than any of the other styles. It folds similarly to a taco, yet conforms so much that it essentially hinges as well. This pad is multi-dimensional: it lies flat, folds over rocks, packs a fair amount of gear, and doubles as a comfortable sleeping pad.
Some pad manufacturers, like Asana, construct their pads with a “hybrid” fold. This style provides a consistent layer of foam on top, so it is hard to bottom out, yet still folds easily.
The ideal pad size varies when it comes to different climbing areas with varying landing conditions. For example, in RMNP, where talus litters the landscape and flat landings are rare, many small pads work better than one large pad. Areas such as Bishop, known for highballs with flat landings, are best for single, large pads covering as much surface area as possible. Large pads average 4′ x 5′ while standard pads are 3′ x4′. Pad thickness usually ranges from 3″ to 5″. Smaller pads, like sliders or sit pads, tend to be much thinner, though the coverage area can be larger. The Organic Slider Pad, for example, has dimensions of 23″ x 35″ x 1″. Many manufacturers consider size based on various other elements. Asana bases their sizes on “ease of carrying, overall pad weight, the ability to fit into most cars, and shipping dimension so that we keep the cost of getting the pad to our customers at a respectable level,” said Asana founder Jamey Sproull.
Big pads cover large surface areas well and are best for flatter landings. On the downside, they tend to be heavier, more expensive, and take up more room. In the summer of 2017, I traveled to Rocklands, South Africa, where many of the tall boulders have big, daunting falls. On the steep, 20-foot, overhanging cave of Un Petit Hueco Dans Rocklands (V9), I grabbed the sandstone edges, happy to have an array of large pads covering the big landing zone. Having large pads under me gave me the confidence I needed to send.
Standard-sized pads are usually lighter and can cover more varying terrain, including rocky or debris-ridden areas. Easier to carry, they provide a good option for traveling. Medium pads can easily be stacked using either a manufacturers strap system, rope, or similar strapping setup, allowing you to carry just as much foam if not more than one large pad. I found this size useful when projecting Crimping Matters, where we had close to ten pads with smaller pads covering rocks and cracks, and medium pads for the base. This made for a protected, multi-pad landing zone. Each climber attempting the boulder that day was able to carry in multiple pads, with standard pads being the most easily stackable.
Small pads, sometimes called “mini” pads, are primarily useful for dabby sit-starts, covering the seams of multi-pad landings, and for spotting. One example of a small pad is Organic’s Half Pad, which measures 2’ x 3’. It adds extra support without the 10 pound burden of a full pad. This thinner, “lilly pad” style can also be used for circuiting on shorter boulders in areas like HP40 in Alabama or Fontainbleau in France. Additionally, these small pads provide a spot to wipe your feet off and a comfortable seat at the boulders. Slider pads function less as a pad to cushion falls and more as a supplementary item. Sliders tend to have very little foam, making them great for covering seams in multi-pad landings and keeping your butt clean for low starts.

Two types of foam—open cell and closed cell—make up crashpads. The two uniquely crafted foams affect falls differently. Closed cell offers more support, while open cell creates more cushioning. Many pads combine both types of foam to create a safe and sustainable structure. Most crashpads use a sandwich structure where layers of closed-cell foam on the top and bottom surround one or more layers of open-cell foam in the middle. The amount of foam used in each pad varies, ranging from three inches in standard pads to five inches or more in larger pads.
Often made from polyurethane, closed-cell foam tends to be stiffer and more resilient. It provides a solid base for bigger falls, as it can endure a fair amount of impact without flexing or bottoming out. This long lasting foam resists weather well because it “helps move energy out toward the edges of the mat,” said Sproull. Most pads have at least one layer of closed-cell foam to provide a solid base. However, solely closed cell foam pads would make for a painful impact, since they provide hardly any cushion. Because of this, most companies combine both foam types in layers for maximum comfort and protection. Crashpad companies tinker with foam ratios to curate a unique pad, catering to climbers’ various needs and preferences. Pads with more closed-cell foam are sturdier and provide better protection on highball climbs, where the impact is greater, and the chance of bottoming out is higher.

Like closed-cell foam, open-cell foam is made of polyurethane. Open-cell foam actually starts out as closed-cell foam and undergoes a process called reticulation. Textile manufacturers throughout the United States use heat to break down the stiffening elements of closed foam to create a more sponge-like consistency. Open-cell foam is slightly softer and more “cushy,” which allows it to better absorb the impact of a bouldering fall. However, the softness makes it more prone to weather damage and this foam wears quicker than closed cell. When taking long falls, open-cell foam puts you at a higher risk of bottoming out—it has a fair amount of give, absorbing more impact than it deflects.
Crashpads are an investment that’s meant to last years, so consider the sustainability of the material. “The lifespan of a pad depends entirely on the number of times it is fallen on, the height from which someone is falling, and the place that it is stored,” explained Sproull. Most manufacturers use a ballistic nylon material such as Cordura. However, some use polyester, an auto upholstery, or velvet topside. Nylon and polyester tend to be durable for synthetic fabrics. Nylon is bit stronger than polyester, though polyester is slightly more weather and abrasion resistant. The outer casing materials vary from pad to pad. Usually, it is the same nylon material around the whole pad, however some pads will include special features such as rubber corners, a velvet top, or carpet material to wipe your feet.
With the exception of mini pads and sliders, which can be fit inside other pads, most pads employ a backpack style harness system. The harness system becomes more important the farther you get from your car. Nothing kills psyche like arriving at the boulders sore from hiking with a poor fitting crashpad. Fortunately, manufacturers have beefed up their harness systems.
Modern harness systems include a waist belt (often padded), padded shoulder straps, a chest strap that buckles, and adjustable straps for each of these attachments. Some pads, such as the Backcountry Pad by Organic and Mystery Ranch, implement an actual backpack harness system to ensure maximum comfort when hiking deep into remote areas. When considering a harness system, make sure that the attachments are adjustable and that the straps and waist belt are padded, especially if you are hiking any kind of distance.
Additional features vary depending on the manufacturer but may include the material used to make the pad, various closure/strap systems, points to attach multiple pads together, or even rug material to wipe your shoes. Some pads include handles on each side so you can carry it briefcase style, which can be helpful for traveling short distances with multiple pads.
Many modern pads also have straps or a Velcro flap that allows for stacking pads together. The Asana Hero and Super Hero pads offer a military grade cargo clip, that allows you to attach you gear to the outside of the pad, avoiding any discomfort from the convex shape that is formed when gear is stored on the inside of the pad.
Before committing to a pad, check out how the pad stores gear. I’ve had shoes fall out of the side of my pad before while hiking between boulders at Upper Chaos Canyon in RMNP. This was a major red flag—no one wants to arrive at their project only to find they dropped a shoe along the way. Most pads offer flap closure systems to secure gear. Additionally, consider how much capacity your pad has for carrying gear. If you hike to remote backcountry areas, you’ll need more than just shoes and chalk. Look for a pad that can accommodate a small backpack.
