Thank you for taking the time to look at my listing for this Arcteryx Proton LT Hoody.

I bought this on eBay UK back in November 2023 but decided I’d prefer the Arcteryx Atom LT instead. The Proton LT Hoody is still in brand new and unused with tags attached.

It’s a men’s sized medium but it is fitted in size type. To give you some idea of what “fitted” means I’m a 36 inch chest and this jacket fits me like a small would because active wear sizing is often an athletic or slim fit so I had to size up to a medium with Arcteryx. So before you buy do check if the sizing is right.

Here is the Arcteryx product description and features list if you want more details:

The Proton Hoody is equipped with a breathable insulation package to manage the dynamic needs of mountain pursuits and perform as a self-regulating mid layer for a variety of high output activities. Breathable insulation means excess heat and moisture can pass through the combination of air permeable fabrics and insulation. In addition to being extremely air permeable, the Fortius™ Air 20 face fabric has unrivaled hardwearing durability, over 60 times more durable in abrasion tests than the industry standard. Coreloft™ Compact 80 synthetic insulation in the body maintains excellent stretch recovery. The No Slip Zip™ keeps the main zipper from self-opening and the helmet compatible insulated hood gives additional warmth. Put it on, leave it on and stay focused on the activity.
