This month's Trends

This month is all about getting ready for changing weather. 

1. From picking up rain gear to enjoying the last month of backpacking by sleeping warmer with a quality sleeping pad and camping cot, you're getting after it.

2. Fluctuating weather can be hard on the body and some athletes find that good-tasting electrolytes help regulate between heat waves and cold snaps.

3. Merino and mesh can help regulate temps, too, whether you're hiking or at home. From merino in our best women's hiking underwear and best men’s hiking underwear to good ol’ hiking socks for our feet, outdoors people know that comfy underwear is totally worth it on hot and cold days.

4. Wet and cooler weather and rain means time to pick up waterproof hiking boots.

5. You love getting outside with your dogs safely. A dog harness in conjunction with a dog leash is safest for your pet and you can use it not just on the trail and while running, but in everyday life, too.
