Putting together a small repair kit

Most gear damage is surprisingly uniform: fabric tears, a seam opens, a buckle breaks, a part comes loose. Behind it there is almost always too much pull, rubbing or ageing. A good kit is therefore planned not around objects but around tasks: something must be held together over an area (tape), something must be joined or lashed down (cord, cable ties), or something must be joined more permanently (needle and thread).

Duct tape is especially versatile because it contains a woven fabric. The fabric takes up the pull, the adhesive holds it to the surface. That way a strip of tape can hold a tear in a tarp or jacket together for many hours. Cord, on the other hand, holds through knots and wraps, and cable ties through a small catch that only lets the strap slide one way.

Sewing is the slowest but most durable of the three methods. Many small stitches share the load, and unlike tape a seam does not let go when it gets wet or cold. That is why a small sewing kit belongs in every kit, even if it is rarely used.

Tape does not need to travel as a heavy roll. Wrap a few metres around a water bottle, a trekking pole or a piece of card. Cord – such as paracord or thin accessory cord – replaces shoelaces, ties down loose parts and becomes a washing line. Safety pins in different sizes close tears and broken zips, and cable ties replace snapped loops.

For the sewing kit, what matters is a strong needle with a large eye and sturdy thread; polyester thread is stronger than thin cotton thread and does not rot. A few spare buttons and a spare buckle sized for your backpack strap are tiny and can save the whole pack when it counts.

Then add what suits your gear: patches for the sleeping pad, a puncture kit for the bike tube, a spare shoelace, a few tent pegs. Everything goes into a small waterproof bag. At home the kit can be bigger: screwdrivers, pliers, a utility knife, a tarp and cord, for example to cover a broken window from the ground after a storm.

A makeshift fix can cope with everyday loads, but not with a fall load. Damaged climbing ropes, harnesses, slings and helmets are therefore never patched but retired. Sewn or taped joins on such gear are off-limits too, however strong they look.

Gas hoses, stoves, cartridges, batteries and power cables are likewise never “repaired” with tape or cable ties. A leaking hose can release gas, a patched cable can cause an electric shock or a fire. One simple rule applies here: broken means no longer used.

Cable ties are handy, but they are hard to open again without a tool. So never put them around arms, legs, fingers or the neck – not even as a joke. And when you cut with a knife, always work away from your body.

The real value of the kit lies in practice. On the way it is often cold, wet or already dark, your fingers are stiff and you are tired. Anyone who tries a repair for the first time in those conditions can easily fail. Anyone who has done it once at the kitchen table knows what to do.

Set aside an evening: sew two ends of an old strap together with an overlap. Tape a tear in a piece of old tarp, once with square-cut tape and once with rounded tape, and see which strip lets go first. Replace a shoelace with cord and swap a buckle. That way you also notice what is still missing from your kit.

Check the kit briefly before every trip: does the tape still stick? Has anything been used up? Old tape can lose its stickiness over time. A kit that is never restocked is empty at the moment that matters.

Mountaineering textbooks have long counted a knife and repair materials among the basic equipment for trips, the so-called “Ten Essentials”. Military survival manuals also stress maintaining the gear you have rather than hoping for replacements. The idea behind it is simple: gear that works keeps you warm, dry and mobile.

A repair kit does not replace a proper repair. It bridges the time until the next workshop, the cobbler, or until you are home and have time. A patched strap should afterwards be sewn properly or replaced.

Less is often more: a kit small enough that you really always carry it helps more than a big box that stays at home.
