Don't know, but look carefully as it's probably not just pockets. More likely to be the quality/thickness of the material, seams, socks etc ?thinking of vision hoppers...seam to be middle of the range? not sure exactly what the difference is between Koski and hoppers, maybe its some pockets or something
I enquired at Norris’s but none in stock, they did say they would get me some, but like you I want to try some on first.I haven't started researching price yet. My foot isn't wet enough to force me into action yet !!
I'd like to try them on because i suspect I am in between sizes so I need to plan a trip to Mr Norris's
If I cant try before buying I may have to order two pairs and send the poorest fitting ones backCheapest on eBay is £275 plus £8 postage.
They only appear to do medium large XL and XXL.
My Ikons were medium short to suit 31” inside leg, nuisance really as poor fitting waders tend to cause leaks.
Review here in which he states he got medium Short https://flyculturemag.com/vision-koski-wader-review/
