Offloading some layers. For sizing reference: I'm 5' 9" 165 lbs, am a pretty standard medium in most clothing, and all of this fits me well. I'm happy to answer any more specific questions!

All listed prices include shipping to CONUS, except for the pack. It would be nice to sell the pack locally (SLC), but am open to shipping.

Trew Cosmic ski shell (Imgur link)
$160

Mammut softshell (Imgur link)
$50
Size: Men's medium
Color: Yellow
Condition: Fair. Some marks from use, possibly washable. The main zipper is quirky - when zipping, you have to hold the bottom stop or it won't pull. Not difficult after you've done it once.
Notes:  This is a relatively close-fitting shell - definitely room for a fleece or thin insulation layer, but not much more than that.  The fabric is thin and pretty packable (packs down to about the size of two baseballs) but feels surprisingly durable and abrasion-resistant. Some stretch but not a ton. I find it's a good cycling shell, especially with the pit zips.

Osprey Mutant 38 (Imgur link)
$90 + shipping
Condition: Great. Used about a dozen times, no structural wear. Just some dirt marks.
Notes: Lockable side lashing, removable brain with secondary top cover when it's off. It's gotten consistently good reviews from Outdoor Gear Lab and elsewhere.
