Reddit mentions of Portwest S440 XL Navy Classic Rain Jacket

As for shoes, I love my New Balance and K-Swiss walking sneakers. You're a new CCA, so don't spend a fortune on sneakers just yet until you're past probation and you're sure you want the job. What part of the country are you in? Winter will be here soon. I live in New England and nothing makes this job more miserable than a pair of cold wet feet & socks. If appropriate, you may just want to get a cheap pair of sneakers to last a month or two and spend the money on some nice waterproof boots. Whatever footwear you buy, always get something that's genuine leather and slip resistant. I can't stress that enough. Don't want to be falling on wet leaves, etc.

As for pants? Khakis, shorts, sweats. Enjoy the freedom you have at this point to wear whatever makes you comfortable.

I bought a $10 raincoat on Amazon that's awesome in the rain.

You're going to get thirsty. A water bottle that can handle an LLV and last the day is a must. I have this one.

Do you like coffee? If so, I carry this. Brew it at home and it stays hot all morning.

If you're not familiar with the town you're working in, you may want to invest in a power bank for your phone so that you don't run out of battery (those LLVs rarely have a working charger!) and can use your GPS.

Another cool thing since it's starting to get dark earlier: a headband flashlight. They help when it's 5pm, you're still out delivering mail and can't read the envelopes or see where you are stepping. My office provides these for free. Check with yours.

As for tips, hang in there! I wanted to quit my first month, it was miserable. I started in November, right before Christmas. It starts to get real busy this time of year and it's very overwhelming. But if you're in a good office, the senior carriers there will help you and the supervisors will understand your position. Best of luck!
