100L Expandable Camping Hiking Backpack Black - Large Capacity

Our review looks at the 70L/100L expandable camping hiking backpack in black and its claim to be a true large-capacity, weather-ready pack for multi-day treks. The bottom line: this bag is aimed at hikers and campers who need a roomy, organized carry that can grow from 70L to 100L and survive wet conditions. It stands out for its expandable storage, multiple external pockets and included rain cover, making it a practical choice when volume and basic weather protection matter more than ultralight weight.

Key Features

• Expandable Capacity: The pack zips open at the base to increase from 70L to 100L, giving extra room for bulky items like sleeping bags and tents when needed.
• Multiple Pockets: One main compartment with drawstring plus a top pocket, front zipper pocket, bottom pocket and two side pockets help organize clothing, tools and water bottles for easy access.
• Waterproof Fabric and Rain Cover: Built from 900D Oxford fabric with a supplied rain cover to improve resistance to light rain and protect gear on wet trails.
• MOLLE Attachment System: Webbing and straps across the front and bottom accept additional pouches or a foam mat, adding modularity for gear attachments.
• Comfort and Ventilation: Widened mesh breathable sponge padding with adjustable shoulder straps, chest strap and hip belt help distribute load and reduce fatigue on long hauls.

Who It's For

This backpack suits weekend backpackers, campers and climbers who carry bulky gear and need flexible volume for longer trips; the expandable design is useful when planning variable-length outings or sharing one pack for multiple purposes. It also works well for those who value organization, since five external pockets and side bottle holders keep small items and hydration accessible.

It is less appropriate for ultralight hikers who prioritize the lowest possible pack weight or for users requiring an internal frame for heavy, technical loads; the pack has no internal frame and weighs about 3.64lb, so heavy loads will still feel substantial without frame support.

Pros & Cons

Our Verdict

The expandable 70L/100L black backpack is a practical, value-oriented choice for campers and backpackers who need high volume, good organization and basic waterproofing without paying for ultralight materials.

Frequently Asked Questions

The 900D fabric is water resistant and the included rain cover improves protection in wet conditions, but it is still best to use dry sacks for electronics and prolonged heavy rain.

No, this model does not include an internal frame; weight is carried on the padded straps and hip belt.

Will it fit a standard sleeping bag and tent?
Yes, with the expansion to 100L the main compartment and bottom pocket provide room for a tent and sleeping bag along with clothing and essentials.
