My husband is the go-to guy for getting the best outdoors gear. He chose the Marmot Oracle jacket as a lightweight waterproof jacket, suitable for wearing by itself or layering over a vest when the temperatures drop. I love the two-way zipper so I can loosen the fit around the hips for better walking. I prefer the men's version since I wear it over a Camelbak or fanny pack when walking.
This is a great jacket for use both with fitness walking and as your everyday jacket for going to work or school. I love the two-way front zipper and storm flap on this jacket. That gives you the ability to upzip it from the bottom so your legs can move freely. It also has enough length to cover your buns and upper thighs. I prefer that for long walks in the rain. It has plenty of pockets, including handwarmer pockets, two chest zip pockets and an interior zip pocket with a cord port perfect for your mobile device. The jacket comes in black, olive, and wine, which would work well for a jacket you wear for walking to work or at work. It doesn't have any reflective elements, so you might want to add some of your own for walking after dark. It comes in regular sizes and in plus sizes.
A yellow rain suit is a walking essential for dreary, rainy days. I was truly pleased with how supple, scentless, and breathable the O2 Rainwear rain suit was. I wore it through several cloudbursts and it kept me dry, with the water beading up and rolling off without soaking into the fabric, while allowing any sweat to escape from inside as well. I wore it temperatures from 50-60F.
This waterproof and windproof jacket comes in men's and women's versions. The reflective elements on this jacket are outstanding. It has a two-way zipper, which you don't often find on running jackets. I prefer a two-way zipper as I like a longer length of waterproof jacket to keep my seat dry, but still want freedom of motion for my legs. I like the number of pockets - an inside media pocket to keep your electronics dry, and an outer zip chest pocket for stuff you need to get to more often. It also has zip side pockets. You can detach the hood. The price is excellent for a jacket of this quality.
The men's version of the PreCip jacket. Warning: the electric blue color offered in previous years (which you may find on close-out) is a most lovely deep purple. And so I inherited it from my husband as he chose a color more suited to his masculine sensibilities. The men's version works great for me.
