> The alpine centre harness is a colour coded version of the original alpine harness which has plenty of benefits for alpine use. It's light, compact, has threadback buckles and doesn't have excessive padding to constrict your movement when worn over multiple layers on long days.
Nothing in the description on the DMM website
http://dmmclimbing.com/products/centre-alpine/ suggests why the "centre alpine" harness is suited to alpine climbing, in fact, the first line in the description "This is the original and highly acclaimed centre harness." seems to suggest that they added the term "alpine" just to make it a bit more sexy sounding.
I accept that the lack of padding does make it a bit more suited to alpine use, as I noted in a post way up top, but, this isn't what DMM are selling the harness on and I'm quite sure that this is a side benefit of the fact that thick webbing is far more resilient than nice squashy comfortable foam padding. They are just saying it's tough, cheap and safe, which is enough for a centre harness.
The fact that it only has a single gear loop as standard (more can be bought and added) also suggests strongly that it isn't a proper alpine harness; can you imagine loading all your gear for a long alpine pitch onto one gear loop? and if you were to buy load more loops to thread on you'd be wasting a small fortune when you can buy a BD alpine bod for £30 which comes with 4 loops already and can be simply fitted over crampons etc.
