Unigear Hydration Pack Backpack — 2L (70oz) Silver Gray with Adjustable Straps, Lightweight Splash-Resistant

Unigear's silver-gray hydration pack is a compact, aerodynamic backpack with a replaceable 2L (70 oz) water bladder and adjustable straps to keep you hydrated and stable during running, cycling, hiking, and climbing.

This lightweight Unigear backpack measures 16.5 x 8 x 6 inches and combines a splash-resistant nylon shell with an included 2-liter BPA-free bladder. Designed for active users who need hands-free hydration, the vest-like fit uses adjustable shoulder, chest, and waist straps to minimize bounce and distribute weight efficiently. A small front pocket provides quick access to essentials without bulk, while the pack’s narrow profile reduces wind drag for high-intensity use.

How does this hydration pack stay comfortable and stable during activity?

Comfort comes from multiple adjustment points: padded shoulder straps plus chest and waist straps let you tune the fit across different torso sizes. The low-profile design sits close to your back to reduce movement, and lightweight materials cut overall burden so you feel less fatigue on long outings.

• Adjustable shoulder, chest, and waist straps for 27–50 inch chest sizes
• Padded straps to reduce pressure during longer wear
• Compact 16.5 x 8 x 6 inch shape that hugs the body
• Double-built waist straps for improved wear resistance and reduced bounce

What hydration features are included and how do they perform?

The pack includes a replaceable 2-liter (70 oz) BPA-free bladder with a screw cap for easy filling and the option to add ice cubes for cooler drinks. The bladder’s airflow system helps maintain cooler temperatures and ensures steady water flow through the bite valve for uninterrupted hydration during high-output activities.

• 2L (70 oz) BPA-free bladder with screw cap for simple filling
• Airflow design to help keep liquid cooler on day trips
• Replaceable bladder for hygiene and long-term use
• Hands-free drinking via integrated hose and bite valve

Is this pack durable and weather-resistant enough for outdoor use?

Constructed from upgraded lightweight, splash-resistant nylon, the pack protects belongings from light rain and trail spray without adding much weight. Reinforced seams and double-built waist straps enhance durability so the pack withstands repeated use across seasons.

• Splash-resistant nylon exterior for light-weather protection
• Lightweight construction weighing about 1.1 lb total with bladder
• Reinforced straps and stitching to extend service life
• Compact aerodynamic profile reduces wind drag for cycling

What can I carry besides the water bladder?

While optimized for hydration and performance, the pack includes a small front pocket sized for essentials—keys, snacks, or a thin phone. The slim storage keeps weight centered and prevents items from shifting during vigorous movement.

• Small front pocket for keys, a granola bar, or a compact multi-tool
• Main compartment sized for the bladder and a few lightweight items
• Minimal internal bulk preserves ergonomic fit and stability

Who is this for: The Unigear 2L hydration pack suits runners, cyclists, hikers, climbers, and active commuters who want a minimal, stable hydration solution. It’s ideal for anyone needing a hands-free water system with a snug fit—teenagers through adults—during training runs, day hikes, or weekend rides where a slim, aerodynamic pack and easy access to fluids are priorities.
