Packs: Deals

Consider your main activity:

• Hiking: Compatible with hydration reservoirs; some have straps or loops to attach trekking poles or other gear.
• Running: Designed to limit bounce; compatible with water bottles or hydration reservoirs.
• Climbing: Slim profile with abrasion-resistant reinforcements.
• Traveling: Has compartments for easy organization; many meet carry-on size requirements.

How much gear will you carry?

• 20L or less: Ideal for short runs, day hikes or quick outings.
• 21–35L: The sweet spot for hiking and travel.
• 36–50L: Best for extended trips or adventures requiring more gear or clothing.

Find the right fit:

• Daypacks are available in a range of sizes.

• Check your torso length and waist against the brand's size chart for the best fit.
• Many packs feature adjustable torso lengths to fine-tune your fit.

Choose a gear capacity 

• Runs under 2 hours: 2 liters 
• Runs 2-3 hours: 2 to 6 liters 
• Runs 3-6 hours: 4 to 12 liters 
• Runs over 6 hours: 6+ liters 

Decide on bottles and/or reservoir 

• Most vests are compatible with both bottles and reservoirs. 
• Bottles are easier and faster to refill, usually holding 500 ml of water each. 
• Bottles can be soft or rigid. Rigid bottles are more durable.  
• Reservoirs hold more water, up to several liters. 

Get the right fit 

• Follow the manufacturer’s sizing guidelines. 
• Choose a snug fit. (Measure your chest while wearing your sports bra.) 
• Leave room for adjustment: The straps should sit in the middle of their adjustment range. 
• Women-specific vests offer fits optimized for the bust and shoulders. 

Choose a bag category

• Wheeled luggage: Easy to roll through airports and on smooth streets; options include duffels, suitcases and backpacks with wheels
• Travel duffel bags: Lighter, simple design and easy to stash, but with limited organizing compartments
• Travel packs: Ideal for uneven terrain and travelers OK carrying a load on their backs

Capacity

• Weekend trips (30-50 liters): Many carry-on duffels, packs and bags fall in this range
• Multiday trips (50-75 liters): Great for trips that last one to two weeks
• Extended trips (75+ liters): Best for big expeditions or longer adventures

Features

• Carry-on: These meet common carry-on guidelines, but always check airline rules before heading out
• Laptop compartment: A dedicated sleeve or section helps protect your device   
• Backpack straps: Some duffels also have dedicated backpack straps for easy hauling
