Staple for Winter and Travel

This is my 2nd Cerium vest. I bought one for layering on a 10 day mostly cold hike with one night at 19k feet. It was perfect, light weight, warm, deep pockets. I do not travel in the winter without it. I will wear my down coat and have this vest in my backpack and after I get through TSA, I switch and pack the coat away. I've worn my other vest 100s of times and it still looks like new but I wanted another color. I wear an XS in regular clothes but got the S here. My other is an M to make room for a heavy layer.

Great vest -- needs some design adjustments

This vest warms you up immediately, inside the store. However, the right size in the chest, is too small for the hips. Please look at a reshaping to accommodate women's hips. Also, if you had a 2 way zipper on the Cerium vest, it could be left undone at the bottom to accommodate the width of women's hips. Some women are pear shaped, small up top, wide at bottom. Lastly, if you could punch up the black colour to a bold, deep dark black it would add punch when paired with Dynasty, Arctic White and Ray jackets. Please try to update this vest by Fall 2026. I need a vest to go with your Gamma and Beta jackets, otherwise Burrrrr... Thanks so much Arcteryx!
