A durable, vacuum-insulated bottle that keeps cold drinks cold for 24 hours on all-day hikes and backcountry trips.
Overview
The Hydro Flask Wide Mouth is a 32-ounce insulated water bottle built for all-day park adventures. Using double-wall vacuum insulation, it keeps drinks cold for 24 hours or hot for 12, eliminating the need for frequent refills at water sources. The wide-mouth design makes it easy to pack ice, fits standard cup holders, and the leakproof chug cap works as both a convenient daily drinker and a reliable backcountry companion. For day hikes in hot climates or multi-day backpacking trips where temperature management matters, this bottle delivers.
Who It's For
Best for day hikers in hot-weather parks who want cold water throughout long outings. Ideal for backcountry camping trips where durability matters. Skip it if ultralight weight is your priority—at roughly 1.5 lbs empty, it adds noticeable pack burden on multi-day trips. Not the choice if you regularly hike shorter routes under 3 hours where a lighter plastic bottle is fine. The Chug Cap isn't designed for hot liquids; consider other Hydro Flask caps if you need coffee or tea on the trail.
Key Features
- 24-Hour Cold Retention: TempShield double-wall vacuum insulation keeps drinks ice-cold through long summer hikes without needing to swap ice or refill from cold water sources.
- Wide Mouth Design: Opens wide enough to fit standard ice cubes and water filter fill tubes. Also means easier cleaning and faster refilling at natural water sources.
- Pro-Grade Stainless Steel: 18/8 stainless steel resists corrosion, dents, and flavor transfer. Built to survive trail impacts, rocky camps, and years of backcountry use.
- Leakproof Chug Cap: Narrow spout controls flow for quick drinks while the cap stays sealed in a daypack. No worry about leaks soaking your gear during rough scrambles.
- Standard Cup Holder Compatible: Tapered design fits vehicle cup holders and hydration pack sleeves, making it practical from car to trail and back.
On the Trail
You're planning a July day hike to Half Dome in Yosemite, an 17-mile out-and-back with exposed granite sections. The forecast shows 92°F at the valley floor, hotter on exposed ridges. Fill this bottle with ice-cold water at the Tenaya Lake Trailhead parking area before starting. Because of the vacuum insulation, that water stays cold through the 6+ hours of actual hiking time. The wide mouth fits ice cubes you can top off if you hit a cold creek crossing mid-hike. The leakproof chug cap means you can drink straight from the bottle without spilling on your gear when scrambling up the Half Dome cables. By late afternoon on the descent, you still have cold water instead of lukewarm liquid from a plastic bottle.

Frequently Asked Questions
Will this bottle keep water cold in extreme desert heat like Death Valley?
Yes. In Death Valley's 125°F summer heat, fill it with ice at your car, and it'll stay cold for 6-8 hours of day hiking. For best results, store it in your pack's shaded pocket rather than in direct sun. Even in extreme conditions, the vacuum insulation significantly outperforms plastic bottles.
Can I use this for hot drinks on camping trips?
The bottle itself can hold hot water for 12 hours, but the Chug Cap isn't rated for hot liquids. For backcountry camping, you'd need to purchase Hydro Flask's insulated lid separately. With the Chug Cap, stick to cold water or cold beverages.
Is this bottle durable enough for multi-day backcountry camping?
Yes. The 18/8 pro-grade stainless steel resists dents from rocky camps and survives years of backcountry use. The main point of care is the plastic chug cap—store it carefully in your pack to avoid cracking during rough transport. Many backcountry users keep these bottles for a decade or more.
Bottom Line
A durable, vacuum-insulated bottle that keeps cold drinks cold for 24 hours on all-day hikes and backcountry trips.
