UltraFlask Speed 600 ML Soft Flask
The Hydrapak UltraFlask Speed 600 ml allows you to drink on the go. Its soft material allows it to fit snugly in most vest pockets and it shrinks as you drink to minimize water movement.
The SpeedFill™ cap flips open for quick top ups at aid stations, and the wide mouth can accommodate drink mixes and ice cubes. The included drinking-tube cap can also be swapped out with a BeFree Filter. You can also use just a bite valve without the drinking tube.
A perfect match for our Vest Straps or for our Water Bottle Sleeves. Grab two bottles for balanced hydration.
- Soft material conforms to most hydration and vest style straps, belts or pack pockets, making it a great addition or replacement running flask.
- Compatible with 42mm threaded backcountry water filters such as the Katadyn® BeFree™ Filter.
- Flexible design shrinks as you drink, reducing water movement.
- Speedfill cap is designed for fast filling - flips open for quick refills and snaps closed for a leak-proof seal.
- Customizable cap lets you choose between two cap options. Directly mount your bite valve onto the cap or insert the adjustable drink tube to create a straw cap (can be cut to any length).
- A high-flow, easy to drink bite valve auto-seals after each sip, eliminating annoying drips.
- The large 42mm opening lets you fill the flask easily with ice and drink mixes.
- External capacity gauge allows you to track your hydration intake or measure out the contents
- Made of ultra-durable, abrasion resistant TPU & RF welded seams for superior durability and elasticity
- Safe and reliable, 100% BPA & PVC free
- Imported.

Zpacks Ventum Wind Shell
Amazingly light but cuts the wind and holds the heat in with a layer underneath!
– Joe B., ★★★★★
Choosing the right layer for crisp spring mornings and chilly fall nights can be a challenge. Our Ventum Wind Shell is crafted to cut the breeze and trap warmth in your base layer or against your skin.
Ventum fabric strikes the right balance between cutting cold wind while still allowing enough breathability for sweat to escape when hiking on chilly mornings and evenings.
It’s perfect for when a base layer alone is not enough, but insulation would make you overheat. Weighing under 2 ounces this is a must-have item for when you plan to hike in cool weather.
This windshell is unisex sizing. We do also have some women's sizes in our Bargain Bin while supplies last.
