I get questions about climbing gear from friends just getting into the sport pretty often. So I finally decided to compile some of my answers in this post so that I can just direct people here. If you are thinking about getting into climbing, I hope this ends up being useful for you.
The amount of gear that you need will depend on the type of climbing you want to do. If you are planning to climb strictly in a gym, then you may only want to buy shoes. You'll probably also want a chalkbag, and if you want to do top-rope or lead indoors as well as boulder, then you will need a harness and a belay device. If you want to boulder outside, shoes, a chalkbag (which you wear while you climb) or a chalkpot (which is bigger and stays on the ground), and a bouldering pad will suffice. If you'd like to sport climb outside, then you will need shoes, a harness, a rope, draws, and a belay device. For traditional climbing... you'll need removable protection, but I won't get into my advice on that, as that would turn this into more of a treatise than War and Peace.
We'll start with what is the simplest, in my opinion.
Harnesses
For harnesses, most anything will do, but I would highly suggest:
1) Adjustable leg loops
2) Plastic gear loops (I don't like the flexible ones, as they make unclipping draws more difficult when leading)
3) Waist adjusters on either side of the belay loop (this enables you to tighten the harness while keeping the belay loop centered).
For me, the ultimate harness is the Petzel caladris. It is lightweight, has adjustable leg loops and two waist adjustments, the inflexible gear loops are pretty sturdy , and the back is vented to keep you cooler (I'm always sweaty... and for me, the reduction in material for the waist loop is huge). The only problem is that it comes at a pretty steep price ($90).
ChalkbagsThough they are pretty simple, there are a surprising assortment of
chalk bags. For the most part, people seem to treat them like an accessory, choosing more for color and design than anything. My criteria for a chalkbag are:
1) Diameter: This is more for people with really big hands. You basically want something wide enough that you don't have to aim much to get your hand into. Consider being gripped and scared on lead and hassling with trying to fidget your hand into your bag to chalk up. I've observed this happen before, and it doesn't look fun.
2) Depth: You want your bag to be deep enough to get your whole hand in there. And everyone knows that there are few things less satisfying that coming up short.
3) Interior material: This is likely a girly thing, but some interiors just feel better than others. I personally like having something cozy to dip into.
Chalk
I personally prefer loose chalk over chalk balls, simply because my fingers tend to ooze when I've been climbing outdoors a lot. If this or sweat isn't a problem for you, you might prefer a chalk ball (I would recommend a refillable one) as they are less messy than loose chalk and might slow your chalk consumption. I use a mixture of powdered chalk and crushed chalk blocks. The powder is useful for overall coverage, and crushing the little chalk clumps with my fingers makes me happy.
Belay DevicesA
belay device is essential for sport and trad climbing, and sometimes necessary for indoor use as well, depending on whether your gym provides belay devices or not. There is a continuing debate between Black Diamond ATCs and Petzl Grigris. I personally learned to belay with a grigri. It is an autolocking belay device, which means it will stop the rope without assistance. An ATC, on the other hand, will do no such thing. Some people argue that grigris are safer, while others hold that ATCs are. I contend that the belay device is only as safe as the person who is operating it makes it. Regardless of the device, a proper belay requires focus, attention, and consideration for the leader. Grigris are great for sport climbing or for belaying top ropers, who will often hang on the rope resting for long periods of time, because they will hold the person without constant pressure being applied to the rope. I prefer ATCs for trad climbing, as they are lighter and easier to rappel with. Grigris are about $75, while ATCs run about $25. For the beginner who isn't sure how serious they intend to get about climbing, I would suggest and xATC, which has grooves to help arrest the rope, and I find also work much better than "regular" ATCs for handling the growingly popular "skinny" ropes.
RopesWhich leads us to
ropes (also necessary for sport and trad climbing). I personally prefer Mammut ropes, which seem to last longer than other ropes, and also don't seem to require the break in time of some other ropes. I prefer to buy them with the dry coating (intended for ice climbing), as it seems to keep them from getting as dirty, and improves the rope handling. Sterling also seems to be a good choice, and I would avoid Beal (they wear out really quickly and I hate the handling) and Blue Water (I also dislike their handling. One of their ropes I used was very slick and would shoot through the belay device unless you kept a steel grip on it while lowering someone heavy. The other actually squeeked when lowering which was very unnerving).
The other thing to keep in mind when buying a rope is the diameter. The smaller the diameter, the lighter the rope will be (typically). But as with anything, there are tradeoffs. Smaller diameter ropes wear quicker and will not hold as many falls safely. I would suggest ropes with at least a 9.8 mm diameter if you want to do any trad climbing (a 10mm rope would actually be preferrable). For sport climbing, I have a Mammut Infinity (which is a 9.5mm), and absolutely love it, but I would not suggest such a skinny rope for climbers over 170 lbs, as these strings will wear out much faster for them.
Bouldering PadsIf you only intend to boulder, you'll likely want a pad. Some things to keep in mind:
1) Foam: The denser foams will hold up longer, but will also not provide as soft a landing. I typically go with the densest I can find, as I have seen people twist ankles on soft pads.
2) Straps: Make sure the carrying system is comfortable enough for fairly long hikes. There's nothing worse than arriving at a great bouldering destination sore and/or blistered around the shoulders.
3) Pockets: Some pads come with built in pockets or compartments. These can be very convenient, but I find that a closure system that allows you to stuff everything inside the pad (and keep it there) when you fold it up, is really nice. (The Metolius "fat bastard" and Black Diamond "drop zone" seem great in this respect.
4) Cover material: The bottom line is that you don't want something that holds dirt. You're going to be throwing this thing on the ground repeatedly, and face it. Who actually cleans their crash pads. Black cotton canvas is okay, but ripstop nylon is nicer.
I would suggest any of the Metolius crash pads (The "cheap bastard" from Metolius is less expensive than other pads and seems quite nice). They typically seem to be well engineered, and the foam in mine has held up rather well.
Climbing ShoesChoosing
shoes can be a really difficult. Your best option depends on their intended use, whether it be sport climbing, trad climbing, bouldering, or some combination? Do you prefer something comfortable, or would you be willing to sacrifice comfort (somewhat) for precision?
And, regardless of these issues, fit varies widely from shoe to shoe. My best suggestion is to go to REI (if you have one) or a local mountain shop and try a bunch on. I can briefly explain some of the differences between shoe features.
1) closure system: The trad climbing shoes are typically laceups, which can improve the specificity of the fit and the precision of the shoe, but if you are bouldering or even sport climbing and taking your shoes off fairly often, repeated shoe tying can become tedious. In contrast, there are velcro shoes (my favorite being the sportiva katanas), which are easier to get in and out of but still have a pretty good fit. Then there are slippers, which have elastic, and are baggier shoes- but still nice for something like bouldering or indoor gym climbing- as they tend to be pretty comfortable.
2) last: Different brands have different types of fits. I tend to stick with Sportivas, as I have high arches and they fit me rather well. Five Tens and Mad Rocks seem to fit wider feet. But even these general guidelines can change from model to model.
3) rubber: Five ten and Mad Rock rubber seem to be the stickiest, but they also seem to wear out quicker. Sportivas aren't quite as sticky, but last longer. Boreal arguably has the worst rubber around, unless you do tons of limestone climbing.
4) downturned toes: Traditional shoes will have flat lasts, which are comfortable for jamming your feet into cracks. Sport climbing shoes have downturned toes that put the majority of your power where it should be- on your big toe. These however, are not as comfortable, so if you
plan to wear them hours on end, (think multipitch trad climb) the you'll end up hating climbing. Your choice depends on the kind of climbing you plan to do.
5) synthetic versus leather: Synthetic typically doesn't change shape much. Leather is harder to predict. I've had Sportiva mythos that have stretched significantly, and Sportiva katanas that have shrunk. (I think the shrinking is a result of my feet sweating and then the leather shrinking as it dries out). So be aware of this when you choose your shoe size.
6) sizing: Some people will suggest that you purchase the tightest shoes you can possibly bear. I say that your first few pairs of climbing shoes should be loose enough that you continue to actually climb. You can buy tighter shoes as your abilities improve.
7) which brings me to cost: Keep in mind that shoes will wear out in proportion to the amount of time you use them. I typically have three different sets of shoes (for the gym, sport climbing, and crack climbing), and they rarely last me as long as a year. Shoes are can get *very* expensive, and so if you are simply looking for the cheapest ones around, I suggest the REI members only garage sales, where you can sometimes get good deals on shoes that have only been used a handful of times. If you want an unused pair at a great price, I would suggest Mad Rocks, but if and *only* if they actually fit you. I have a pair that sits in our gear closet, because it feels to me as though they had alien's feet in mind when designing the last.
