They're due to launch two new bags in the Spring, the Levity and Lumina. the 60l bag is 830g but otherwise seems to be much the same shape as the exos but a bigger looser mesh pocket and the dual entry side pockets look to be more dual than before, which I don't like as bottles go in easier but fall out easier too. But for the price of $260 could get an arc haul, although I suppose the Levity will be available in the UK. Looks rather fragile.

I am going to be interested in seeing those when they're finally released though I'm wary of the pricing.
Nothing in the updated Exos or Eja that makes me want to switch out my Exos 38 for one of them.
