Review 1 flags packability as a weakness, which aligns with the video reviewers' concern about bulk and portability.
In their words
“I’ve been living in the Gamma MX Hoody since October, and it’s the first jacket I reach for whether I’m heading to the local crag or just grabbing groceries in sideways sleet. The Wee Burly Double Weave doesn’t look techy—more like a beefy work shirt—but it shrugs off wet snow and chalk dust with the same indifference.”

“I was very confused with this jacket. Some says it's awesome and some says it's a trash. It took me a while to figure out how to use this. I have 2 Gamma MX, one size M and the other size L. M fits tight, L is roomy. I bought L first considering this as a 'shell'. It works good with size M Atom or Cerium inside.”
