Western Mountaineering is a well known and top rate American fabricator of sleeping bags.  The Highlite is their ultralight summer bag weighing only 455g with 225g of 800+ down.  Comfort level +2.  This is the 6' bag with left zip.Please see the full specification on the Ultralight Outdoor Gear website or on Western Mountaineering's own site:https://www.ultralightoutdoorgear.co.uk/equipment-c3/sleeping-bags-c21/sleeping-bags-c88/highlite-sleeping-bag-p354ConditionI have only slept in this bag once, wearing long johns.  It has been stored at all times in its lofting bag. Unfortunately, I stored it on a top shelf near a lightbulb which burned a hole into both the lofting bag and the sleeping bag.  I mended the sleeping bag with transparent iron on fabric, please see pictures.  This is a great shame but it is a fully functional and clean bag, except for this mended hole.PriceThe best UK price I could find for this bag new is £298.00 - from Banana Fingers.  I'm giving a £50 discount for the hole.  Free postage by Collect + tracked service within the UK.   If you are bidding from outside the UK I will probably use Amazon's Global Delivery service but if you are in the EU let me know as it will be cheaper if I post it to you direct and I will need to get a quote. Any questions, please ask.Clare
