My current harness is on the way out partly due to getting a bit slimmer than when I first bought it but also I've had it a fair while now, but i'm struggling to replace it because I appear to be in between sizes.

Most harnesses I've tried from BD, Arcteryx, Petzl and Beal so far have all been sized 28-30 or 30-32 (or thereabouts), in all the 30-32's the fit is close if not ideal but the buckle is cranked to absolute maximum, no movement for getting slimmer but the next size down will be a poor fit with the belay loop way off to the side or the leg loops being too tight.

Does anyone know of any harnesses that might be more 29-31?

This is me exactly, in between small and medium.  I'm coming back to the conclusion I am gong to have to get one with a floating waist belt like the DMM renegade (I think Edelrid do one too). A bit chunkier than I wanted, but works, especially if you are into trad as it has loads of gear loops for easy racking. 

Pick a harness with 2 buckles or a floating belt. 

Mammut togir , medium is 73 to85 cm, roughly 29 to 33 inches 

Get a 30-32 and eat more pies.

This one: 437 g

Or Renegade, 415g in medium. DMM do a Renegade 2 and renegade 2 Pro; what's the difference?

The buckle, quick vs thread through. 

thanks

Same issue hear I use to have a Togir which fitted well but found the leg loops dug in too much on semi/hanging belays, I ended up with an arc'teryx (on sale green one with non adjustable leg loops). I have to sinch it up to its tightest but it fits really well and I doubt I'll be losing any weight + it has 5 gear loops.

This is a funny question as I would have thought that when the temps change, so does the layers of clothing I wear. Still, perhaps 2 harnesses, 1 for cold and 1 for warm could work.

i'm a 29-30ish waist. Tried on a DMM renegade in M and S, ended up getting the S. I've used it for summer with just a t-shirt & windshirt and for winter over base layer, midlayers and hardshell no problem. The floating waistbelt is great - had previously had a petzl calidris and, before then, a gourou.

I have the Ocun Twist Tech because of the floating waist belt. Works fantastic! And  ususally somewhat cheaper than other brands.

Just been delivered of a Climbing Technology Ascent for the vry reason you cite - I love the Arcteryx I've had for 5 years now for everything except the sizing - like you I'm between sizes - large is a bit big with thin clothing; medium puts the gear loops too far back.

Went for the CT ascent as it has a large range for a given size and has two buckles. Not used in earnest yet but initial signs are it's going to be right. Light and compact too, with 6 gear loops.

It could...

That said, even if I do own harnesses for winter use and for summer... I still end up using about the same size. The specialisation is mainly due to different requirements for winter and summer... albeit a few of the harnesses end up gettin' used for both.
