I've had a Moon Saturn for over 18 months. Rate it. Foam beginning to give but no issues with stitching. The new model has a waist belt which would be good. Tend to bungee cord other mats to it rather than put them inside. Taken a highish horizontal fall onto it recently with little damage which was encouraging
I'm also not convinced that Moon pads have the polythene to protect the foam from UK weather as the review claims. More likely it makes getting the foam into the pad easier. On the downside this can lead to a 'slipping' effect of the foam against the outer shell in some cases where the landing isn't perfectly flat.
Organic pads - bought two when we came to North America. Really impressed with the foam and build quality. The design means that the straps are on the underside of the pad when in use which is fine in perma-dry Bishop but more of an issue in UK mud unless you take a tarp with you. Biggest downside is probably the cost from importing them. 175 dollars for a simple pad in the US v 180 quid at Banana fingers.
Anyone had an alpkit project before ? looks fucking massive not sure about quality though
