I have a LPP that I bought this fall and used all season. I love the jacket, but... when I first bought it, it was really puffy. I looked like the Michelin man wearing it. It was incredibly warm and puffy. After a season of use, it’s a normal jacket. It certainly isn’t puffy any more and the insulation is really flat. It’s still warm, but not the crazy warm when I first bought it. I’ve maybe washed it 3-4 times, in accordance with the directions, using mild technical detergent and hang drying. Is this normal for a LPP? I gotta say, if this is normal, I’m pretty disappointed. I splurged on the jacket and made a special trip to the store when I was in CO. I love everything else on the jacket, but the Insulation has not impressed me after a season of use.
