When you're hitting the trail for a three-day trek, every ounce matters. An overloaded pack can sap your energy, slow your pace, and turn your dream hike into a slog. That’s where a solid ultralight gear checklist comes in.

At Light Hiking Gear (formerly Aarn USA), we’re all about smarter packing. Our gear is designed to keep your base weight low without compromising on safety or comfort. Here’s your go-to list of what you actually need—nothing more, nothing less.

Shelter That Balances Protection and Packability

You don’t need a palace on the trail—just enough shelter to stay dry and warm. Choose options that are simple, weather-appropriate, and easy to set up.

Essentials:

• 1-person or 2-person ultralight tent (under 3 lbs)

• Groundsheet or Tyvek footprint

• Compact stakes and guylines

• Optional: lightweight tarp for added rain protection

Tip: Browse our range of ultralight hiking packs that balance carry comfort with space efficiency for shelter storage.

Clothing Layers for Changing Conditions

Weather can shift fast. Pack lightweight, moisture-wicking layers you can mix and match depending on the forecast.

Essentials:

• Base layer (synthetic or merino)

• Mid-layer fleece or down jacket

• Rain jacket and pants

• Quick-dry hiking pants and T-shirt

• Comfortable hiking socks and underwear

• Lightweight gloves and a beanie

• Trail runners or hiking shoes (broken in)

If you need to buy camping socks online, choose pairs that are made of breathable materials like merino wool and are blister-resistant—your feet will thank you after mile 15.

Cooking and Food Prep Gear

You’ll need a compact cook system that does the job without bulk. Skip the multi-course meals—opt for easy, high-calorie foods instead.

Essentials:

• Portable stove and fuel

• Titanium or aluminum pot

• Spork and mug

• Lightweight food bag with odor-proof liner

• Water bottles or bladder

• Water filter or purification tabs

Keep your entire cook system under 2 pounds. You'll find great pairings in our light camping gear collection.

Safety and Navigation Must-Haves

These are the “just in case” items that often get overlooked but can make or break a trip. Keep them in a top-access pocket for easy reach.

Essentials:

• Trail map and compass (even if you use GPS)

• First aid kit (customized for you)

• Sunscreen and lip balm

• Insect repellent

• Multi-tool or knife

• Headlamp with spare batteries

• Emergency whistle

Bonus Comfort Items (If Weight Allows)

If you’ve nailed your essentials, consider a few trail luxuries:

• Inflatable pillow

• Lightweight camp chair

• Journal or book

• Compact power bank

• Extra snacks (obviously)

Use a lightweight backpack approach—trim unnecessary items and weigh your pack fully loaded before hitting the trail.
