Arc'teryx Beta LT vs Arc'teryx Cerium Lt Hoody

Arcteryx make the best jackets. This is my second Beta LT after giving my first one to a good friend. Excellent product, kept me warm and safe during several mountain ultra marathons.

* Warm, has armpit perforation for breathability, extremely comfortable and versatile. I bought it for $20 and it is probably the single best item in my list.

I’m a size 36 waist, which sometimes suggests a size L, and I sometimes find myself between Arc sizes with broader cut pieces like the Fission SV or LEAF Cold WX LT fitting me better in a L. Certain fleeces like the Delta LT and Kyanite LT also fit me best in a L, so I had some concerns the Acto FL might be a bit too baggy, but it is a very trim cut piece and ultimately fits exactly how I wanted it to.

I would suggest buying it from somewhere with free returns and trying a small and a medium - I suspect you might prefer the small if you're just wearing it over a shirt.
