Icepack uses Insuloft, Rohan’s own development (the brand has been working with fine-fi lament synthetic insulation since the late 1970s, so could be regarded as a pioneer in the field). In this case, Insuloft is a thin layer of low-lofting microfibre polyester. It is minimal enough to walk in and warm enough to add rest-stop oomph, while being easy-care in the typical vein of synthetics. Icepack has a square fit which, while lacking any finesse or style, allows it to fit over multiple layers (and makes it too baggy over a base layer alone). Also, the zip has no baffle so in cold conditions chill slips through the zip. Length is generous, with side-adjusted shockcord. Zipped side pockets have a brushed face, while a mesh zipped pocket inside doubles as a stuff sack. The collar is partially lined with brushed fabric but this doesn’t extend to the top or front of the collar. Combined with a lack of chinguard, this results in an uncomfortable zip-end and breath/ sweat-slippery polyester against the chin. These zip-related issues are the main detractions from an otherwise versatile winter gilet.
