So collective UKC, looking for a replacement Arcteryx Psiphon?
Which I used as a windproof over base layers on walk ins, as a highly breathable soft shell over a double pile fleece to keep spindrift and light precipitation off when climbing and walking on the tops in Scottish winter (note that the hood took a helmet) but light enough you could throw a goretex over it too, or in summer when you forgot your sun cream you could suffer a bit as a sun proof, or wear as a multi pitch rock windproof (happy to suffer a bit of baggyness so that it could be used with more insulation in winter). wide cuffs with Velcro were appreciated to allow gloves to fit under.
