Quick answer: choose a daypack (about 15–35 L) for single-day hikes, a backpacking pack (about 40–65 L) with a frame and hip belt for overnight and multi-day trips, and a frameless ultralight pack only if your total load is light. Hydration packs and running vests suit fast, light trips.
The right pack makes every hike more comfortable. Here’s how the main types of hiking pack compare.
Types of Hiking Packs Compared
| Type | Capacity | Pros | Cons |
|---|---|---|---|
| Daypack | 15–35 L | Light, simple, affordable | Limited support for heavy loads |
| Hydration pack / vest | 5–20 L | Very light, easy drinking on the move | Little space |
| Internal-frame backpacking pack | 40–65 L | Carries heavy loads comfortably, good hip belt | Heavier, pricier |
| Ultralight frameless pack | 30–50 L | Very light | Uncomfortable with heavy loads |
| External-frame pack | 50–80 L | Carries awkward loads, airy back | Bulky, less stable on rough ground |
How to Choose
- Trip length: day hike, overnight or multi-day.
- Torso length: measure from the base of your neck to the top of your hip bones and match it to the pack size.
- Hip belt: essential above about 10 kg.
- Ventilation: a mesh back panel helps in hot weather.
- Access: top-loading vs panel (zip) access.
- Features: hydration sleeve, hip-belt pockets, rain cover.
Why a Quality Pack Is Worth It
A good pack that fits spreads the weight onto your hips, reduces shoulder and back pain and lasts for years. On a budget, see our backpacks under $50, but prioritise fit and a proper hip belt for heavier loads.
