I am also looking for an alternative to my S4 gear one. I have been pretty happy with the s4 but it does ride up my neck which becomes uncomfortable when out all day and sometimes for multiple days. I am looking at a number and found a great site called blackovis.com which has many different offerings. They do not ship to the uk at present.
One of my preferred ones is also from Alaska guide creations which do appear to ship to uk but have to confirm cost. If anyone out there wanted to share an order and the shipping costs I'd be up for bringinging a few over together.
Have been using S4Gear for 2 or 3 seasons and very happy with them. They were around $90 on EBay with expensive shipping from US. Ordered directly from S4 website for $29. They don’t ship to Ireland but used AddressPal, a mail forwarding service operated by the Irish Postal Service so S4 thought they were sending to a US address.
