Pick a bag that is too small, and gear ends up tied to the outside. Pick one that is too big, and you pack things you never use. Both make the trail harder. This guide helps you choose the right size for your trip, with the OUTCLAZ trekking backpacks that fit each one.
What do the litres mean?
Litres show how much space is inside the bag. A 30L bag holds about as much as a large school backpack, while an 80L bag can hold camping gear for a week. Dimensions matter too, so check height, width and depth against your body. A tall, narrow pack feels different from a short, wide one.
Match the size to your trip
| Trip | Bag size | OUTCLAZ options |
|---|---|---|
| Day hike | 30L | Venture |
| Weekend trek (2-3 days) | 40-50L | Terra, Ride, Ignite, Glide, Armor, Techpack |
| Longer trip (4-5 days) | 60-65L | Hicker Hub, Tanent, Freedom |
| Week-long trek or expedition | 70-80L | Treckmaster, Dominator, Tusker, Terrain, Ranger |
Do not buy bigger “just in case”
Extra space fills up quickly, and a heavy pack tires you faster. A common rule of thumb is to keep a loaded pack at about 20% of your body weight or less. If most of your trips are 2-3 days, a 50L bag is usually enough.
Check the fit, not only the litres
- Shoulder straps: adjustable and padded, so the load is spread across your shoulders.
- Back panel: a breathable air-mesh panel reduces sweat on long climbs.
- Buckles and zippers: durable buckles and YKK zippers matter after days of use.
- Bottle holder: lets you drink without taking the bag off.
- Try it loaded: add weight to the bag in the shop or at home, walk around, and adjust the straps before you decide.
Plan for rain
Mountain weather can change within minutes, and Kerala’s monsoon can soak a bag quickly. Look for water-resistant fabric, and consider a bag that comes with a rain cover. Eight OUTCLAZ trekking models include one: Ignite, Glide, Freedom, Treckmaster, Dominator, Tusker, Terrain and Ranger.
Will it carry a laptop?
If you travel for work before or after a trek, look for a laptop sleeve. Most OUTCLAZ trekking and travel packs have one.
Common mistakes
- Choosing the biggest bag because it looks “safer”.
- Ignoring how the bag sits on your back.
- Packing heavy items at the bottom or far from your back.
- Forgetting a rain cover or a waterproof liner.
