Why a tiny repair kit is worth its weight

Wild camping in the UK uplands has a way of finding weak points in your kit. A gust funnelling down a Lakeland pass can split a flysheet seam; a sharp granite edge under a tussock can put a pinprick in a sleeping mat; a tired aluminium pole can snap as you pitch in the last of the light. None of these need to end your night. With a small, well-chosen repair kit and a little know-how, you can keep a tent standing and a mat inflated until you are back home. The trick is to carry less than you think you need, but to know exactly how to use it.

Mending a torn tent fly or inner

First, get the tent pitched and sheltered. A repair made in a howling wind will fail. Clean the area around the tear with an alcohol wipe or a dab of hand sanitiser on a cloth, then let it dry. Dirt, silicone spray and condensation are the enemies of adhesion.

For small tears in a flysheet or groundsheet, use a clear repair tape. Cut a patch with rounded corners — sharp corners peel up — and make it at least a centimetre larger than the damage on every side. Press it firmly, then warm it with your hand for a minute. If the tear is on a seam, apply a thin bead of seam sealant over the stitching and let it cure. For a longer rip, sew it with a needle and strong thread first, then tape over the top. Duct tape will get you through a night, but its residue is miserable to remove, so treat it as a temporary fix.

Midge netting is fragile. A small tear can be taped, but a hole in the door zip is best repaired by sewing with fine thread and then sealing. If the pole sleeve has torn, tape it smooth before you re-thread the pole, or the split will snag the sections and make things worse.

Splinting a broken pole

Most pole failures happen at a ferrule or where a section has been bent one too many times. Do not cut the shock cord. Instead, slide a pole repair sleeve or splint over the break. If you do not have one, a spare pole section, a sturdy tent peg or even a short length of alloy tubing will do. Tape it tightly at both ends, then wrap cord or a cable tie around the whole splint for extra stiffness.

If a ferrule has split, whip it with dental floss or strong thread, then coat the whipping with seam sealant. Pitch the tent with the repaired pole on the leeward side and reduce the tension on that section. Keep the pole straight as you feed it through; a sharp bend will only break it again. Check the splint for sharp edges and tape them before they chew through the sleeve.

Finding and fixing a sleeping mat leak

A mat that goes soft overnight is usually losing air from a pinhole, a valve or a seam. Inflate it fully, then submerge it in a tarn, a stream or a bothy sink. Look for a stream of bubbles. If the water is too cold or shallow, mix a little washing-up liquid with water in a spray bottle and mist the mat; the leak will foam. Mark the spot with a scrap of tape.

Dry the mat thoroughly. Apply a patch from your mat repair kit, pressing out any air bubbles, then weight it down for the time stated on the kit. A warm bothy helps the adhesive cure. Valve leaks are often caused by grit or a missing O-ring. Clean the valve, check the seal and tighten it gently. A smear of silicone grease can revive a stiff valve. Self-inflating mats can delaminate internally, and baffles can fail; those are not field repairs, so plan to replace the mat when you get home.

Working in wind, wet and midges

Use a bothy as a repair workshop when you can. Its table, light and shelter make a huge difference, and you can leave the place clean for the next person. Do not wash soapy water into a tarn; use the water only for leak detection, and carry out every scrap of tape and packaging. If you are caught out on the hill, pitch the tent and work in the porch with the door closed. Keep patches and glue warm inside your jacket. Cold hands and cold adhesive make for a poor repair.

What to carry and how to practise

Your repair kit need not be large. A good starting point is:

• Repair tape — clear, strong and flexible, for flysheets, groundsheets and midge nets.
• Duct tape — a few metres wrapped around a pen or pole section for emergency use.
• Seam sealant — for stitching, seams and whipping repairs.
• Needle and thread — strong thread, plus a thimble if you can manage it.
• Pole splint or spare section — sized to your tent’s poles.
• Mat patch kit — patches and adhesive suitable for your mat’s fabric.
• Alcohol wipes — for cleaning before any patch.
• Small scissors, cable ties and cord — for cutting tape and holding splints.
• Spare guyline and a peg or two — because repairs often need extra anchorage.

Practise at home before you need these skills. Patch an old mat, splint a broken pole, sew a tear in a retired flysheet. Then, when a tarn-side leak or a snapped pole happens at dusk, you will already know what to do. A little preparation keeps your kit working, your night comfortable and your wild camping trip on track.
