I have just taken delivery of this quilt, i have not used it as yet; so what follows is simply initial observations: I'm 6ft tall and ordered the long version of the quilt as one of the key selling points of quilts for me is the ability to wrap the quilt around/over me as conditions dictate. Specs here: https://www.thermarest.com/new-2019/vesper-20 I was happy to wait for this quilt to be available in the UK as it had all of my desired features. And upon receipt, I have to say I am extremely impressed - the quality is immaculate. I have far too much gear and already own high quality bags from the likes of PHD and Western Mountaineering - the Vesper quilt is of at least the same standard of manufacture as these brands. The loft is amazing and the perimeter side baffles look like they will be highly effective. The foot box is also shaped (unlike many bags/quilts which have a simple oval plug) - this was an important feature for me to be able to accommodate my size 13's without compressing the foot area which usually leads to cold tootsies... Aside from using the quilt as a stand-alone item, I plan to pair it up with my As Tucas 133g Sestrals quilt which will make me damp-proof for extended winter trips, and i reckon that the combined quilts will see me comfortable to around -15c - not bad at all for around 1200g total.
