Pack Systems
Pack & Carry
Guide
Day pack sizing, hydration systems, and how to keep your phone accessible for AR without the fumble.
Day Pack Sizing
The most common packing mistake: too much bag for a short hike, or too little for a long one. Match your pack to your day, not your ambition.
Hip Pack / Running Vest
Under 5 miles, minimal gear, fast movement. Ideal for Sendero's AR discovery sessions on well-maintained trail. Water bottle holder, phone pocket, and that's mostly it.
Day Pack
The sweet spot for most hikers. Room for layers, lunch, first aid, and 2L of water. Enough pockets to keep gear organized without the weight penalty of a larger bag.
Overnight Pack
When you're carrying a shelter, sleeping system, and multiple days of food. At this size, fitting and load transfer become as important as capacity.
For Sendero Maps users, a running vest with a chest phone pocket is the ideal setup. Your phone stays at eye level, accessible in under a second without breaking stride. No more rooting through your pack every time you want to point the camera at a ridge.
Top Packs for Sendero Maps Users
All four have accessible phone pockets — a non-negotiable for AR hiking. No more stopping to dig through your main compartment.
Salomon Active Skin 8
Eight liters of storage in a vest that fits like a second skin. Two front chest pockets fit your phone and a soft flask simultaneously. The 1.5L soft flasks are included. Ideal for Sendero sessions where you want to shoot AR without breaking stride. The stretchable mesh front pockets let you reach your phone without stopping.
Osprey Talon 22
The Talon has earned its reputation over two decades of day hiking. Large hipbelt pockets fit a full-size phone on each side — accessible while walking. Hydration reservoir compatible (up to 3L), external hydration tube route, and a suspension system that actually breathes. Trampoline mesh back panel keeps air moving.
Nathan Pinnacle 12L
Built for heat. The open mesh back panel creates a true air channel between your back and the pack. Dedicated phone sleeve in the hipbelt. 1.8L hydration bladder included. The 12L is the right size for desert hiking (Big Bend, Guadalupe Mountains) where you're carrying more water but less clothing.
Gregory Zulu 30
Thirty liters in a load-transfer suspension that punches above its weight class. Massive hipbelt pockets — large enough for a full iPhone Pro Max with a chunky case. Floating top lid with extra storage pocket. 3L hydration reservoir compatible. The choice when you're doing serious mileage with real gear.
The 10 Day Hike Essentials
These ten categories have kept hikers alive for decades. They're not optional on anything beyond a neighborhood walk. Sendero Maps covers #1 — here's the rest.
Navigation
Sendero Maps (downloaded offline) + backup GPS device or printed map. Don't rely on cell signal.
Sun Protection
SPF 50+ sunscreen, UV-blocking sunglasses, brimmed hat, UPF-rated shirt. Reapply every 2 hours above treeline.
Insulation
Emergency layer even on warm days. Weather turns fast at elevation. A lightweight packable puff jacket adds 4 oz and can save your life.
Illumination
Headlamp with fresh batteries + backup batteries loose in your pack. Don't hike by phone flashlight — it drains the battery you need for AR and navigation.
First Aid
Blister kit (Moleskin, Leukotape), SAM splint, Benadryl, ibuprofen, wound closure strips, nitrile gloves. Know how to use it.
Fire Starting
Disposable lighter + waterproof matches as backup. Store matches in a waterproof container. Tinder cubes add almost no weight.
Repair Tools
Multi-tool or knife, duct tape (wrap a few feet around your water bottle), repair patches for your pack or inflatable mat.
Nutrition
200+ calories per hour of hiking. High-density, low-weight: trail mix, energy bars, jerky. Always carry more than you think you need.
Hydration
2L minimum to start, more in desert heat (1L per hour). Water filter or purification tablets. Never count on a water source being clean.
Emergency Shelter
Emergency space blanket (2 oz, $3) or a bivy sack. If you're stuck overnight in the wrong conditions, this is the difference that matters most.
