Time-Saver Guide to Choosing a Rucksack
Posted by Andy Neil on Feb 20, 2025
A good rucksack should feel like an extension of your body—distributing weight efficiently, keeping you comfortable, and ensuring easy access to essentials. Here’s how to choose the right one quickly and effectively.
1. Fit and Sizing
A well-fitting rucksack makes all the difference. Measure your torso length (C7 vertebra to iliac crest) to find the right size. For more information on fitting a rucksack, read our Ultimate Guide to Lightweight Rucksacks.
-
Hip Belt: Should sit on your hip bones, carrying 70-80% of the weight.
-
Shoulder Straps: Pull the pack close to your back
-
Sternum Strap: Helps stabilise the shoulder straps.
-
Load Lifters: Small but crucial straps that pull the pack closer to your body for balance.
2. Choosing the Right Volume
“The right size pack is the one that fits your gear.” Overfilling a 40L pack is uncomfortable, while underfilling a 70L pack adds unnecessary weight. Avoid strapping bulky items like a tent or sleeping mat outside—they can shift your balance, get damaged, or fall off. Keeping gear inside ensures stability and protection.
-
15-35L: Daypacks – for short hikes and everyday use.
-
40-60L: Multi-day packs – ideal for overnight or weekend trips.
-
60-80L+: Expedition packs – for extended trips or winter camping.
3. Framed vs. Frameless
The structure of your pack impacts weight distribution and comfort.
-
Framed: Transfers weight to hips, more comfortable for heavy loads.
-
Frameless: Lighter and more minimalist but less supportive for heavy gear.
4. Lid or No Lid?
Your pack's closure system affects accessibility and weather protection.
-
Lidded Packs (“Brain”) – Extra storage and weather protection.
-
Lidless (Roll-Top) – Lighter, simpler, and more water-resistant.
5. Key Features to Consider
Additional features can enhance comfort and accessibility.
-
Suspended Back Systems: Reduces sweating but shifts weight away from your body.
-
Hydration Sleeve: Internal pocket for a water reservoir.
-
External Pockets: Quick access to snacks, maps, and waterproofs.
-
Hip Belt Pockets: Great for snacks, phone, or a GPS device.
-
Compression Straps: Prevents shifting and improves balance.
-
Attachment Points: Loops and holders for trekking poles, ice axes, or extra gear.
6. Waterproofing
Weather protection varies depending on the design and accessories.
-
Fully Waterproof Packs: Durable but heavier and costly.
-
Pack Liners/Dry Bags: Lighter and modular, keeps gear dry inside.
-
Rain Covers: Quick solution but can be affected by wind.
Ideal for fast-paced adventures and long-distance trekking.
-
Running Vest Harnesses: Distributes weight across the chest, reducing shoulder strain.
-
Chest Bottle Pockets: Easy access to hydration without removing the pack.

The best rucksack is one that fits well, carries weight efficiently, and suits your adventure. Try before you buy, load it up, and adjust the straps to ensure comfort!
