If Motohaus/Keis finally sort their shit put and put the connection boxes, controllers, switches, etc in the right place it would be a good start!
They asked me some time ago for a full write up and review of their kt as a long time user.
Gave them a number of suggestions about placements, cable runs, switch locations, etc but to date they have not taken a single one into account.
In the real world whilst very warm - their kit struggles due to the locations of cable exits, switch locations and other very small things that make a very big difference to how they work out in the wild.
The X800 glove is a classic example. Plenty warm enough for -8 at 4am in Chamonix in december BUT NOT when they then switch off because the switch fouls the cuff of the jacket........ Put it on the thumb bridge.
The T102 trousers are great apart from the controller not being in the right place to come outside of textiles OR allowing the insoles to be controlled INDEPENDENTLY of the trousers!
Also the connection box sits right on the hip where outer layers apply pressure.
The J103 jacket is so warm you almost don't need to switch it on BUT the ridiculously large knitted cuffs mean its virtually unwearable with any of the more modern jackets from Rukka/Klim/etc.
Make it a nice slim lycra/stretch cuff and it would work great.
Slim the whole jacket down too - no point making a really thick outdoor jacket for motorcycle use. Take a note from the BMW heated vest - super slim and very warm without any bulk at all.
Gerbing could learn from this too.
