Things to Consider Before Buying
- Size matters: 20-35L for day hikes, 35-50L for overnights, 50-65L for multi-day trips. Getting the right size means you carry what you need without excess bulk.
- Torso fit: Backpacks are sized by torso length, not height. Measure from the base of your neck to the top of your hip bones. Most packs come in small, medium, and large or have adjustable suspensions.
- Hip belt quality: On longer hikes with heavier loads, the hip belt carries most of the weight. A well-padded hip belt is essential for comfort. Cheap packs often skimp here.
- Ventilation: Mesh back panels and channels for airflow keep your back from becoming a swamp. This matters more than you think, especially in warm weather.
- Rain protection: Some packs include rain covers. Others have water-resistant fabrics. If you hike in wet conditions, make sure your gear stays dry one way or another.
Frequently Asked Questions
What size hiking backpack do I need for a day hike?
A 20-35 liter pack is perfect for most day hikes. It fits water, snacks, extra layers, a first aid kit, and other essentials without being oversized. Go toward 35L if you carry camera gear or extra supplies.
How should a hiking backpack fit?
The hip belt should sit on top of your hip bones and carry about 80% of the weight. Shoulder straps should wrap comfortably without gaps. The pack should not extend above your head or below your hips.
Is a frame backpack necessary for day hiking?
Not usually. Frameless or simple foam-backed packs work fine for day hikes under 20 pounds. For heavier loads or multi-day trips, an internal frame makes a significant difference in comfort.
