Snow Peak UltraFlask 500ml

Jump to: Our Verdict / Features / Specifications

A Lightweight bottle that will pack flat when empty. 

Montane says: 

The Montane UltraFlask™ 500ml by Hydrapak® is a compactible flask for quick, easy hydration when on the move. The flask compresses for easy storage and prevents water from sloshing. The new wider top opening allows for quick and easy filling / cleaning, whilst the high performance soft silicone bite valve provides a high flow rate.

Our Verdict

Montane’s 2023 UltraFlask is made by Hydrapak, who are experts in soft bottles and hydration bladders. So, you know you’re going to get a high quality product that works. Soft bottles are just that, soft, it might take a bit of getting used to. When you go for a big glug of water the bottle changes shape as it empties, this is great for making more space in your pack as the day goes on.
