How to Choose the Right Pack: A Quick Guide

When it comes to buying a pack, whether for running, hiking, or travel, there’s more to think about than just how much stuff you can cram into it. Picking the right pack can make all the difference when you're out there, so here are a few key things to consider before you buy.

1. Size and Capacity

The first thing to figure out is how much gear you need to carry. Pack sizes are usually measured in liters, and this tells you how much the pack can hold.

Running packs and hydration vests are small, usually under 20 liters, and are designed for carrying just the essentials—water, snacks, and maybe a jacket. Something like the Macpac Amp Ultra 15L Running Vest is perfect if you need something streamlined for a day on the trails.

Daypacks are in the 20-30 liter range, perfect for short hikes or daily use.

Overnight or multi-day packs go from 30 liters and up, with 50-60 liter packs being common for multi-day hikes. If you're heading into the backcountry for a few days, you’ll need a bigger pack like the Macpac Harper 50L for carrying your tent, food, and extra layers.

Expedition packs go beyond 60 liters and are built for serious adventures, where you’re carrying everything including the kitchen sink!

2. Fit and Comfort

Fit is crucial. A poorly fitting pack will make even a short trip uncomfortable. Look for adjustable straps, hip belts, and chest straps so you can tweak the fit to your body.

Hip belts are a big deal if you're carrying heavy loads—they shift the weight from your shoulders to your hips, which helps with balance and reduces fatigue.

Ventilation is important too, especially for bigger packs. A well-designed back panel can keep you cool by allowing airflow between you and the pack.

Make sure to try a few different sizes and adjust the straps so that the pack sits snugly on your back without sagging or pulling.

3. Materials and Durability

What your pack is made from matters, especially if you’re heading into rough conditions.

Ripstop nylon is a common material in lightweight packs, giving you good strength without extra weight. It’s used in packs like the Hyperlite series and holds up well to wear and tear.

TPU-coated fabrics give extra waterproofing and durability, so if you’re planning to be out in wet weather, this is something to look for.

If you’re after a bombproof pack for rugged use, heavier nylon fabrics will be more durable but can add a bit of weight. Think about what kind of terrain and conditions you’ll be in, and choose accordingly.

4. Water Resistance

Not all packs are waterproof, so if you’re planning to be out in the rain, check if the pack has a rain cover or if it’s made from waterproof materials. Some packs have a DWR (Durable Water Repellent) coating, which can handle light rain, but for full waterproofing, look for packs with sealed seams or TPU coatings. For example, the Macpac Jetstream Rainpants would pair well with a pack that offers similar rain protection.

5. Access and Pockets

How you access your gear matters too. Some packs open from the top, while others have front zippers or even full clamshell designs where the whole pack opens up.

Pockets are handy for organizing your gear. Look for side pockets for water bottles, hip belt pockets for snacks or maps, and stretchy front pockets for stashing gear you need quick access to, like a rain jacket. I have found hip pockets to be a gamechanger keeping stuff like food or a GoPro close to hand for when you need them fast.

If you’re using a hydration system, It can be helpful the pack has a sleeve for a bladder and a port for the drinking tube.

6. Weight

The weight of the pack itself is something to consider, especially if you’re going on longer trips where every gram counts. Ultralight packs are great for those who want to move fast, but they often sacrifice a bit of durability and comfort. Heavier packs can be more comfortable and last longer, but you’ll feel that extra weight on your back.

7. Special Features

Some packs come with extras like detachable daypacks, trekking pole attachments, or even ice axe loops for alpine adventures. Think about what you really need—there’s no point in paying extra for features you’ll never use.
