Altus H30 vs J30

[Jenyat53]

Could someone please clarify the difference between the H30 and J30?
As I age I am thinking of trading in my trusty old 10 camino Ferrino Trekker (I don’t walk in hot weather, open zip at every opportunity and have never been soaked) on an Altus as they are significantly lighter but while some swear by the Altus a number of reviews both in this forum and others complain about being soaked beneath their Altus … so feeling a bit apprehensive about the swap.
(I wonder if those complaining simply didn’t realise that you can ‘stew’ in your own moisture from within if you have no air circulation ) or whether occasionally the Altus does fail.
Many thanks in advance for your responses.

At risk of sounding like a kook...OK I might be past that point...but may I suggest the:

Poncho impermeable de montaña y trekking máx. 75 litros Adulto Quechua 900

Compra en Decathlon Poncho impermeable de montaña y trekking máx. 75 litros Adulto Quechua 900 Diseñado y probado en los Alpes franceses, este poncho de manga larga está provisto de cremallera entera para ponerlo fácilmente.

It has huge pit zips for ventilation, is rated at 5,000 schmerber, so very waterproof, and can be seen from space. At 45 Euros, it is affordable.
The money that you save...should you see anyone on the trail with a backpack like that in the profile picture, buy him a beer, or three.

@Gobsmacked by the World that looks very good. @Jenyat53 I replaced my expensive Altus with this which I’ve found much better, at a quarter the price. It does not have pit zips but mine is extra large so lots of air flow.
