Thule Uptake Hydration Pack – Black, 4L | Hands-Free Hydration for Biking & Hiking

Overview

Meet the Thule Uptake Hydration Pack in sleek black, a compact 4-liter backpack designed to keep you fueled and focused on the trail. Its streamlined silhouette hugs your torso, reducing bounce whether you’re sprinting up a gnarly ascent, cruising a dirt path, or carving turns on the slopes. The standout feature is Thule’s magnetic ReTrakt hose, which returns to its resting position after each sip, helping you keep one hand on the grip and one eye on the terrain. The included Hydrapak reservoir is easy to clean thanks to a slide closure, and its locking bite valve helps prevent leaks when the pack is not in use.

Inside, a tidy 4L of storage holds the essentials—pump, tools, nutrition, and a light layer—without weighing you down. An external quick-access pocket keeps a phone within reach, while internal pockets help you organize smaller items so you don’t waste time searching. The harness uses perforated foam and a breathable backpanel to stay cool during climbs, and an integrated sternum strap adds stability on uneven ground. Reflective trim and a tail light attachment boost visibility in low light, helping you stay seen as conditions shift.
