What are your 10 "best" bits of kit? i.e. those that you have used loads and they've never let you down. Mine would be:
Terra Nova Quasar tent
Rab Ladakh sleeping bag
Paramo Cascada jacket
Lowe Alpine Stormweave trousers
Berghaus Arete 45 daysack
Rab Shadow Hoodie
Petzl Tikka Plus headtorch
Extremities Boreas Banded Beanie
1990s Scarpa Manta boots (before they were stiffened)
Cocona/MeCo base layers (Rab/ME/Sprayway)
All of the above have had 1000 days/nights of use (except for the Shadow and the Cocona, which aren't old enough yet but are well on the way).

In reply to Iain Thow:

MEC light weight fleece 'heavy weight base layer' (for me its a mid layer)
MEC thermal top (in light grey which is THE most practical colour)
MEC faced fleece (before people branded such things as softshells)

All of these are going strong after 15 years and are the basis of layering for me whatever the weather

BMC waterproof maps
Coleman alpine gas stove
TNF Atlantis day sac (absolutely no bells, whistles, extra pockets etc)
MacPac Pursuit - bombproof

In terms of Gear:

Mammut Galaxy ropes
Camalots
Rocks and Wall nuts

In reply to Iain Thow:

Snugpack pile shirt elite. Have had this for about 6 years and used it for everything.
Alpkit Gourdon. Used loads, everywhere. Kept my kit dry plenty of times.
Grigri 1. Great bit of kit for the indoor wall. Tons of other lesser applications.
Red chilli spirit VCR. Very happy with these. Must've used them almost every day of the year for everything from DWS, indoors, bouldering, trad, sport. Should've bought another pair but thought I'd save some money and get mad rocks. Regretting that.
BD momentum sa harness. Use it for sport, single pitch trad and indoors. Simple robust design.
CAMP orbit screwgate. Bought as it is so light, to keep my prussicks on. Exactly what I needed, barely notice it's there.
WC 240 sling. Most oldies will grumble but it's so easy to equalise everything at the belay.
DMM bugette. My belay plate for skinny ropes. Works very well and weights nothing at all.
Beal 30m wall rope. Incredible hard wearing single that has had lots abuse indoors and on the grit.
Nike base layer. You can get them really cheap from sports direct and they work brilliantly.

Arcteryx EON merino base-layers - Best fit, articulation and quality, expensive but they get so much use its worth it.
