Carry Comfort

The Mountain Hydro Sling is designed for active, single-strap carry. Key comfort features:

• Adjustable shoulder strap: The padded strap is fully adjustable, allowing you to dial in fit whether worn crossbody or slung over one shoulder.
• Removable strap: The strap detaches completely, so the bag can be used as a standalone pouch or packed flat.
• Bike loop: A dedicated attachment point lets you secure the sling to a bicycle handlebar or frame — ideal for trail riding and commuting.

Bottle Fit

The Hydro Sling is built to carry a standard reusable water bottle in its exterior slip pocket. Recommended bottle dimensions for a secure fit:

• Height: Up to ~9" (23 cm)
• Diameter: Up to ~3" (7.6 cm) — fits sizes up to most standard 32 oz. Nalgene bottles.

Hydration Access & Strap Retention

• The exterior bottle pocket keeps your water within easy reach without opening the main compartment.
• An adjustable drawstring top ensures strap retention, holding bottles snugly during movement.
• The sling is designed for reusable water bottles — it does not include a hydration bladder sleeve or reservoir compatibility.
