I used this for marathon training and then the marathon. I would fill up the night before and then throw it in the fridge overnight. Water wasn’t ice cold the whole time but it was nice and cool. The first couple sips might be warm from the tube but after that it was really refreshing. I think if you add some ice it would keep the water really cold. Easy to clean. No issues with leaks. Glad I bought it. Review: Excellent Replacement for Nathan - My Nathan VaporAir came with a non-insulated bladder, which simply doesn’t cut it in the Texas heat or on day-long hikes in warm weather. I got a Nathan insulated reservoir, which was atrocious: nasty chemical taste that wouldn’t go away after many washes and soaks in baking soda; a terrible design meant to minimize sloshing (a non-existent issue if you fill your reservoir properly) but which made the reservoir very difficult to slide into the hydration vest; and a lining too rigid to pull the reservoir inside-out for cleaning. The Hydrapak bladder solves all those problems. The bladder keeps my water appropriately cool over an entire day in mild weather (although you’ll want to slide an ice pack between the bladder and your body on warm and hot days); it is fully reversible for cleaning; and I did not experience any chemical taste after the first use (I’d filled it with a baking-soda solution prior to first use as well). It pairs very well with the HydraFusion Insulated Tube, which actually kept my water much colder than the reservoir itself in mild weather (due to not being in contact with my body heat). My only wish would be for the reservoir to be slightly bigger. It hasn’t been an issue yet, but my original bladder was 1.8L, then 1.6L for the Nathan insulated bladder, and this one only 1.5L. It should be possible to design a 2L bladder that fits most hydration vests. ## Features - INSULATED RESERVOIR & TUBE: Keeps water colder longer and won’t sweat in warm temperatures. - FITS VESTS & PACKS: A perfect fit for most standard hydration vests and packs. Universal hanger is compatible with clips, hooks & loops in a wide range of packs. - GRAB TAB: Light and flexible grab tab makes it easy to pull in and out of packs. Slide-Seal top opens extra wide, making it easier to fill and add ice. - HIGH FLOW VALVE: Lightweight, self-sealing Comet bite valve can be opened & locked with one hand. - 100% BPA FREE & EASY TO CLEAN: Reverse the reservoir for deep cleaning and complete drying. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BRBRR735 | | Best Sellers Rank | #13,570 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #22 in Outdoor Backpack Reservoirs | | Brand | HydraPak | | Brand Name | HydraPak | | Capacity | 1.5 liters | | Color | Clear | | Customer Reviews | 4.3 out of 5 stars 621 Reviews | | Global Trade Identification Number | 00834456003144 | | Included Components | Velocity Insulated Reservoir 36” HydraFusion Insulated Drink Tube High Flow Comet Bite Valve Plug-N-Play® connect system to easily disconnect the drink tube from the reservoir for easy filling Basic care and use instructions | | Item Type Name | Hydration Reservoir | | Item Weight | 7.68 ounces | | Manufacturer | Hydrapak | | Manufacturer Part Number | AS381 | | Material | Polyurethane (PU) | | Material Type | Polyurethane (PU) | | Model Number | AS381 | | Number Of Pockets | 1 | | Number of Items | 1 | | Number of Packs | 1 | | Sport | Camping & Hiking, Cycling, Running, Snowboarding | | Sport Type | Camping & Hiking, Cycling, Running, Snowboarding | | Strap Type | Adjustable | | Tank Volume | 1.5 liters | | UPC | 834456003144 | | Warranty Description | Beyond Lifetime Warranty, Lifetime Warranty | ## Product Details - **Brand:** HydraPak - **Color:** Clear - **Item Weight:** 7.68 ounces - **Material:** TPU, ABS, POM, PP, EPDM, Silicone, 304SS, TPU Coated Nylon Fabric - **Sport:** Camping & Hiking, Cycling, Running, Snowboarding ## Images ![HydraPak Velocity IT Hydration Reservoir (1.5L or 2L) - Image 1](https://m.media-amazon.com/images/I/713Yxiw+dTL.jpg) ![HydraPak Velocity IT Hydration Reservoir (1.5L or 2L) - Image 2](https://m.media-amazon.com/images/I/71C3eQpVqGL.jpg) ![HydraPak Velocity IT Hydration Reservoir (1.5L or 2L) - Image 3](https://m.media-amazon.com/images/I/81EddN2VO7L.jpg) ![HydraPak Velocity IT Hydration Reservoir (1.5L or 2L) - Image 4](https://m.media-amazon.com/images/I/81mXeIcX6BL.jpg) ![HydraPak Velocity IT Hydration Reservoir (1.5L or 2L) - Image 5](https://m.media-amazon.com/images/I/71MqA4d6OFL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Keeps water cold *by K***. on January 10, 2026* Keeps water pretty cool.

The slide opening at the top is very convenient and much better for cleaning. The hose is insulated like the bladder, both feel very durable. The bite valve is a little hard but I easily got used to it. This should last me a good long time hiking and mountain biking. ## Frequently Bought Together - HydraPak Velocity IT (1.5L or 2L Hydration Reservoir) - Insulated Water Bladder/Reservoir for Hydration Pack – Self-Sealing Bite Valve, Leak Proof and Dishwasher Safe - HydraPak UltraFlask Speed (500ml or 600ml) - Collapsible Soft Flask Water Bottle for Hydration Vests and Running Packs with Easy Open Cap - HydraPak SoftFlask Speed 500ml - Compressible Soft Flask Water Bottle, Perfect Fit for Hydration Vests and Running Packs with Easy Open Cap (500ml/17oz) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/525719993-hydrapak-velocity-it-hydration-reservoir-1-5l-or-2l](https://www.desertcart.jp/products/525719993-hydrapak-velocity-it-hydration-reservoir-1-5l-or-2l) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-19*
