Activ down disappointment

I purchased this item just shy of 12 months ago and have just started wearing it. At the time I also purchased the Arktis lI jacket in black. This I wore straight away and have been really impressed with the quality but more so the stated warmth this jacket generates . This brings me onto the Aktiv down gillet which I have been really unimpressed with the warmth this generates or lack of? This item replaced a Berghaus with a FP rating of 650 as opposed to this item being 700 but I have been left really disappointed with how this doesn't keep me anywhere near as warm as the older item? As the jacket is so warm could this be a faulty item or not as stated. I really like your clothing brand I get compliments and comments all the time. I have sent an email to the support centre but have had no reply whatsoever?

Look forward to hearing from you.

Thank you for taking the time to leave a review, Michael.

Great gilet

I’m normally a medium but this was too baggy round the waist. I wanted a snug fit to look sharp and also keep the warmth in. Really impressed with the gilet, looks great in rust colour, very happy and it’s packs down really really small!
