We love the sun as much as the next person, but try to limit our exposure as much as possible while backpacking.
Below is a list of our suggestions for how to protect yourself from the sun while backpacking:
If you read anything on sun protection, one of the first suggestions is to avoid hiking during mid-day, when the sun is at it's strongest. While it is not possible to entirely avoid backpacking during the hottest part of the day, we do recommend waking up early to get a head start on the heat.
Wear sunscreen! You can skip out on most other personal hygiene products while backpacking, but do not forget your sunscreen. We recommend bringing at least SPF 30, and applying it throughout the day.
Wear a hat— we prefer wearing a ball cap while backpacking. If you are used to wearing a wide-brim hat, try it out with your backpack before you leave for your trip. Sometimes the back of the hat will bump into your backpack, so make sure you try it out and adjust your pack before you hit the trail.
Bring pants and long sleeves, just in case. While you don't have to hike in them the whole time, having a pair of pants and long sleeve shirt is essential to cover your skin during the hottest part of the day.
Speaking of long sleeve shirts, we LOVE sun hoodies. These are lightweight and are typically made with UV protectant material, so they keep the sun off of you as much as possible. The best thing about a sun hoodie specifically is the lightweight hood that protects your neck and ears. Wear a ball cap with one of these and you are set!
Our favorite sun hoodies include:
Womens— Freefly: Bamboo Lightweight Hoody, Mountain Hardwear: Crater Lake Long Sleeve Hoody
Mens— Patagonia: Capilene Cool Daily Hoody, Freefly: Bamboo Lightweight Shore Hoody
Another great piece we've found are sun gloves. They are made from the same UV protectant material, and keep you hands protected from the sun.
Wear sunglasses! Make sure your sunglasses provide UVA and UVB protection. We also recommend having polarized glasses, they make everything in nature stand out more.
