Sore armpits ?

[JohnAC]

cmburch - don't need one with single webbing
netdoc - modified hog? explain!
watchmanjc - i agree with tsandm, get softer webbing. i had really stiff webbing and suffered the same thing as you, now i don;t thanks to softer webbing. I got my webbing from a Salvo dealer.

Right on, thanks for the confirmation!

netdoc - modified hog? explain!

Sure. It's not quite a standard hog rig. On my waist belt, I use a Dive Rite pocket on the left side and I have D-Rings on both sides. My canister light is clipped directly to my plate. My scissors have a bolt snap on a short length of cord attached to the lower eye which is threaded through the upper eye. This keeps it closed when clipped off to the right d-ring (with my lift bag) and yet quickly accessible. Small variations from a true Hog rig (as I understand it), but they really work for me.

You can also try seat belt pads. I used to get chaffed and pretty sore around the arms/chest area but these helped.

loosen the harness a little bit?

i second the strap cross tip. if you're narrower across the shoulders than the 'average guy', it will bring the straps closer to your neck & further from your upper arms.

hope you didn't trim the webbing yet...if you did, you might need another length of it.

loosen the harness a little bit?

This is exactly what i needed. Anyway, i found my hog harness a solution to biggest fit problem i've had with pretty much any BC/Shoulder i strap i used prior. I could never get full lungs of air because i could never find a "tight" or "loose" enough position for the sternum strap... Sounds a bit silly but it is true.
Back to subject.. i use DiveRite hog harness and find it soft / comfortable enough even with a just a t-shirt in the pool.

While everyone has mentioned the strap of your harness might I suggest taking a look at where you may have any D-rings on the shoulder straps (if you are wearing D-Rings)

Having the rings not set correctly it is not uncommon causing the diver to feel the pressure from them following or during a dive. If the d-rings are at the points of where your arms meet your shoulders you may be adding to that pressure as you move your arms in and out and about. D-rings for most people are located up near/just below the collar bone (within reason) this permits their access and minimizes their compression aginst the arms and shoulders.
