Fully functional little under quilt I bought from someone on BPL who made it under the name MNML Gear.  It’s a half length 50f apex underquilt I’ve used for a few seasons that performs to it’s temp rating.  It weighs an ultralight 6.5oz in it’s stuff sack and is a touch smaller than most 1/2 sized UQ’s. For me at 6’2″ and 190lbs it required a bit of diligence to keep beneath me, but it always worked well.  I wouldn’t recommend this UQ for anyone bigger than me.   I’ve recently upgraded and want to make sure this continues to get used by someone as it’s a terrific quilt with plenty of life in it and a bargain at this price. Plus it’s purple on one side and orange on the other!
