1. Osprey Daylite Plus — Best Overall Daypack
The Osprey Daylite Plus has been one of the best-selling daypacks in the world for years, and the latest version keeps the winning formula. At 20 liters, it fits a rain jacket, snacks, water bottle, first aid kit, and sun protection — everything you need for a full day hike without encouraging overpacking. The front panel stretch mesh pocket is perfect for stashing layers on the go.
What makes the Daylite Plus special is the balance of weight (1 lb 4 oz), organization (laptop sleeve, internal organizer pocket, dual side water bottle pockets), and Osprey’s legendary durability. The breathable mesh back panel keeps your back cool, and the sternum strap with whistle adds a small safety feature. And like all Osprey products, it comes with their All Mighty Guarantee — free repair for any reason, any product, for life.
Key Specs:
- Capacity: 20 liters
- Weight: 1 lb 4 oz
- Dimensions: 18″ x 10″ x 9″
- Hydration compatible: Yes (sleeve for reservoir)
- Laptop sleeve: Yes (fits up to 15″)
- Hip belt: Removable webbing belt
- Material: 210D Nylon ripstop
Pros: Perfect size for day hikes, Osprey lifetime warranty, laptop compatible, versatile trail-to-city use
Cons: Hip belt is basic (no padding), 20L can be tight for winter layers, very popular (you’ll see them everywhere)

2. REI Co-op Flash 22 — Best Value
The REI Flash 22 is the daypack that punches way above its $55 price tag. At just 13 ounces, it’s one of the lightest fully-featured daypacks on the market. It has a hydration sleeve, breathable back panel, adjustable sternum strap, removable hip belt, and dual side stretch pockets. The rolltop closure lets you expand capacity when needed or cinch it down for smaller loads.
The Flash 22 uses recycled ripstop nylon that’s surprisingly durable for its weight. The large front stretch mesh pocket swallows a rain jacket easily. It’s the daypack that r/Ultralight recommends for people who want a capable pack without ultralight prices. REI’s satisfaction guarantee means you can return it if it’s not right.
Pros: Incredible value at $55, ultra-lightweight (13 oz), hydration compatible, recycled materials
Cons: Minimalist padding (not great with heavy loads), rolltop not as quick-access as zippers, thin material requires careful handling around rocks
3. Deuter Speed Lite 21 — Best for Active Hikes
If your day hikes involve fast-paced scrambling, trail running, or steep terrain, the Deuter Speed Lite 21 is designed for movement. The body-hugging fit and low-profile design keep the pack stable even when you’re scrambling over rocks or moving at speed. The Aircomfort back system creates airflow between the pack and your back, which makes a real difference on sweaty uphill climbs.
Deuter’s German engineering shows in the details — YKK zippers, reinforced bottom panel, internal hydration sleeve, and trekking pole attachment loops. At 1 lb 2 oz and $90, it’s the performance-oriented choice for hikers who want their daypack to keep up with them, not slow them down.
Pros: Excellent ventilation, stable on-trail carry, trekking pole loops, German build quality
Cons: Less organization than Osprey, no laptop sleeve, $90 is close to the budget limit

4. Gregory Nano 20 — Most Comfortable Carry
Gregory is known for making some of the most comfortable backpacks in the business, and the Nano 20 brings that expertise to the daypack category. The FreeFloat suspension system creates a gap between the back panel and your spine for superior ventilation, and the padded shoulder straps are noticeably more comfortable than competitors at this price.
The Nano 20 also features a dedicated rain cover built into the bottom pocket — a rare feature at $80. The hip belt has small zippered pockets for phone or snacks, and the top lid pocket gives quick access to sunscreen, keys, or trail maps. If comfort is your top priority, Gregory delivers.
Pros: Best comfort in class, integrated rain cover, hip belt pockets, excellent ventilation
Cons: Slightly heavier (1 lb 6 oz), less streamlined for speed hiking, rain cover is small

5. MYSTERY RANCH In and Out 22 — Best Packable Daypack
The In and Out 22 stuffs into its own hip belt pocket, weighs 10 ounces, and expands into a fully functional 22-liter daypack. It’s designed as a summit pack — something you stuff in your main backpack for multi-day trips and pull out for day hikes from base camp. But it also works brilliantly as an everyday travel daypack that takes up zero suitcase space.
Despite being packable, it has a comfortable padded back panel, breathable shoulder straps, a hip belt, and 210D nylon construction that handles trail abuse. MYSTERY RANCH’s military heritage shows in the durability — this is not a flimsy packable bag. At $59, it’s one of the best values on this list.
Pros: Packs into its own pocket, ultralight (10 oz), surprisingly durable, great travel companion
Cons: Minimal padding vs dedicated daypacks, no frame sheet, limited organization when packed out

How to Choose the Right Hiking Daypack
Start with capacity — 18-22 liters is the sweet spot for most day hikes. Under 18L gets tight with layers and food; over 25L encourages overpacking. Next, check the back panel ventilation — a ventilated or suspended back panel makes a massive difference in comfort on warm days. Finally, decide if you need a hydration reservoir sleeve or prefer using water bottles in side pockets. Both work fine, but reservoirs let you drink without stopping.
Frequently Asked Questions
Is a 20L daypack big enough for a full-day hike?
Yes, for most 3-season day hikes. A 20L pack fits a rain jacket, 2L of water, lunch, snacks, sunscreen, first aid kit, and a headlamp with room to spare. In winter when you need extra insulating layers, a 25-30L pack is more appropriate.
Do I need a daypack with a hip belt?
For loads under 15 lbs (typical for day hikes), a hip belt is nice but not essential. It helps transfer weight off your shoulders on longer hikes. If you’re doing 8+ mile days or carrying a hydration reservoir, a hip belt adds noticeable comfort. For short hikes under 5 miles, shoulder straps alone are fine.
What’s the best daypack brand?
Osprey, Gregory, and Deuter consistently make the best daypacks. Osprey’s lifetime warranty is unmatched — they’ll repair any Osprey product for free, for any reason, forever. REI’s house brand offers the best value, and MYSTERY RANCH brings military-grade durability to the consumer market.
Final Verdict
The Osprey Daylite Plus ($75) is the best overall daypack under $100 — it does everything well and comes with a lifetime warranty. The REI Flash 22 ($55) is the best value if weight savings and price matter most. And the MYSTERY RANCH In and Out ($59) is the ultimate packable daypack for travelers and multi-day backpackers who want a summit pack that disappears when not in use.
