You might have one from me (LSoH) or you might have another you made yourself or from another vendor. What has been your temperature range of use and comfort. Please give the fabric outer and AD weight when commenting. For instance : 10D outer / AD90 - then comment.
If you have no fabric layer please state that as well. I know mine all have one layer of fabric and then AD.
Personal use: (Older guy with slower metabolism)
10D Layer with AD 90 : I have used this on it's own in the summer and find it's pretty versatile for warmer temps. I think I could do +16/17°C with it and find reversing it so the fabric is on the inside and AD on outside allows me to use in warmer temps without it being too hot.
10D Layer with AD120 : I use this one the most. Being able to flip it inside out is a key element. This one gets used in summer plus as an overbag in winter for frost layer. It has replaced my Primaloft or Climashield TQ as an overbag.
Temperature range on it's own allows me to do about +12/14°C nicely.
Let everyone know your experiences.
