I like down. Always have. Surrounded by my downy goodness I've always felt so much more comfortable and warm compared to those I've been with in their synthetic bags. Now, that's not to say synthetic doesn't have its place ... I get that ... and I completely understand when synthetic can be more useful than down ... but I've never had a problem using down. I've only been cold twice in the last ten years using my various down quilts or bags and on both occasions it has been my fault with the quilt or bag getting wet ... On my first trek-lite meet I managed to wriggle out from under my trailstar during the night as it was raining and only woke after the bag became completely sodden. The second was due to poor moisture management in my duomid (I had lowered all edges to the ground and not left any gaps for airflow). I have since learnt how best to set my shelters and now use a borah bivy when not using an inner. ... problem solved. However, having been out with the likes of @Jamess and his MLD and As Tucas quilts, @Enzo and @Dave Vaughan with their MYOG apex quilts I decided that maybe, just maybe it was time to give synthetic insulation a try. @Marco 's autumn discount appeared just as I was suffering from man-flu and in a moment of weakness I fired off a couple of questions to which he quickly replied. Marco was very helpful with suggestions to my anticipated uses; chiefly as a summer quilt in a variety of conditions and as an over-quilt for my down. Had he not been so quick, I might have been back at work ... with no new quilt. However, I decided to go for it and ordered an apex 167 quilt in medium wide. It took nine days from the point of order to delivery. One week to make and send and two days being couriered. Impressively quick ... and for once no extra postal or customs charges My first impressions are very positive. 650g by my scales (660g on the website) and the lightweight 12D Schoeller face fabric feels surprisingly soft and comfortable. Seams are minimal and stitching appears excellent to my untrained eye with no loose threads or blemishes. Holding the quilt up to the light reveals no apparent flaws with the apex. I feel that @Marco 's reputation for manufacturing excellent products is justified. The quilt is impressive in how small it compresses and can fit in a 4L stuff sack, although to be honest I will probably use a 9L dry bag or one of Paul's packing cubes since I do not like to overly compress my quilts. The only 'issue' I have ... and this is just a personal preference ... is that the external fabric is loose from the insulation (see last picture). Now I know that apex is a single sheet of material and is only attached at the edges but this surprised me and just doesn't feel right to me at the moment. I guess it is something I will learn to live with since down quilts are completely different. At least I will not have to shake to redistribute the insulation with this quilt. This Sestrals Quilt from As Tucas is my first synthetic quilt, and I am looking forward to putting it through its paces; namely multi day hikes in the damp drizzle of the UK and as a winter over-quilt. My first outing will be next month on or around Cadair and then again on the SDW meet. Hopefully pictures and comments to follow. Could I become a synthetic convert? Time will tell. But for now I can certainly recommend my experience with Marco and AS Tucas.
