When you're choosing between large backpacks and daypacks, the decision usually comes down to how much volume you need versus how much comfort and organization you want built in. Here, the 100L Expandable Hiking Backpack and the Night Cat Backpack take two very different approaches to that same question.
Quick Verdict
The 100L Expandable wins on sheer room and a lower listed price, while the Night Cat wins on built-in comfort and organizational extras. Pick the first when maximum carrying space matters most; pick the second when you're willing to pay more for ergonomic support and added outdoor features.

Where Each Product Wins
- 100L Expandable: maximum room at the lower price. This pack is rated for a full 100 liters and uses a zip closure that keeps contents secure. It's the lower-priced option in this head-to-head.
- Night Cat: comfort and carry organization. The Night Cat's padded, adjustable shoulder, chest, and waist belts make it the more comfort-focused companion for longer carries.
Product Notes
100L Expandable Hiking Backpack
At $25.99, this pack is the less expensive of the two and the only one rated at 100 liters. The multi-compartment layout separates clothes, shoes, water bottles, electronics, and gear, and the hidden compartment adds an extra place for smaller valuables. Expandable sizing lets you increase capacity when you pack out. The zip closure helps keep items from slipping out, and it fits a max 15-inch laptop. The described condition is New without tags, so if you expect the presentation of a tagged retail piece, keep that in mind. For someone who wants one large, simple carry-all for multi-day trips without paying extra, this is the straightforward pick.
Night Cat Backpack Hiking Camping Cycling Waterproof 70L / 90L Daypacks Bag
At $60.49, the Night Cat is the more feature-loaded choice. It comes in Army Green with a 70L / 90L capacity and uses a drawstring closure. The design includes a cover bag, a separate main body, and a bottom bag, so smaller categories of gear have their own homes. The ergonomic back structure with thickened, adjustable shoulder, chest, and waist belts is built to release burden on long trips, and the extra straps can be used to hang a tent, sleeping bag, or trekking pole. A rain cover is also included. The tradeoff is the higher price and the drawstring opening, so you'll want to cinch it well to keep contents from shifting.
Final Choice by Use Case
Choose the 100L Expandable when multi-day trips are your priority and you want the largest volume for the lowest outlay. Choose the Night Cat when you'll be carrying camping or cycling gear and value support and separate storage rooms enough to justify its higher price.
