West Biking 10L Hydration Backpack — Foil-Lined Bladder Compartment, Hose Port

West Biking 10L Hydration Backpack: Foil-Lined Bladder Compartment, Hose Port, About 317 g

This 10-litre pack from West Biking is built to carry a water bladder on rides. It has a bladder compartment that the supplier describes as insulated (it is foil-lined in the supplier’s photos), with hook straps to hold the bladder, a hose outlet at the top and a hose fastening port on the shoulder strap for the drinking tube, and two front pockets on the straps that the supplier says take a phone or snacks. The supplier lists it at about 317 g, in Black Grey, Blue or Purple.

One thing to know first: the listing never says a water bladder comes in the box. Its photos show a drinking tube in use, but nowhere in the listing, its specification table or its video is a bladder listed as included, so plan on using your own unless we confirm otherwise. We have not tested one yet: the figures on this page come from the supplier’s listing for model 0707441, which we read on 7 October 2026, and we say when something is the supplier’s claim.

What You Get

• A foil-lined bladder compartment. Inner hook straps hold the bladder. The supplier calls the compartment a thermal/cold layer, a dual insulation layer, and sells it as “Winter Warmth & Summer Cool”; the listing gives no temperature or time figure.
• A route for the drinking tube. A hose outlet at the top of the pack and a hose fastening port at the top of the shoulder strap, per the supplier’s diagrams.
• Storage beyond water. A storage layer with compartment dividers, side storage pockets, and a drawstring cord across the front panel.
• Two front pockets on the shoulder straps. The supplier says they can store “energy supplies and mobile phones”; its photos show a water bottle in one of them.
• The harness. Adjustable straps, a back panel the supplier calls a honeycomb air-vent design, two buckled straps across the front in the supplier’s photos, and reflective strips on the shoulder straps with an attachment loop for small items. The supplier’s description calls it “wide breathable shoulder straps and waistband”.

Before You Order

Bring your own bladder, or ask us first. The listing gives no bladder size, so compare your bladder’s flat size with the pack: about 25 × 6 × 47 cm by the supplier’s hand measurement, which it says can be off by 1–3 cm. Treat it as water-repellent. That is what the supplier’s own specification table says: the fabric repels water and the zipper is not waterproof, so in steady rain keep a phone or anything that must stay dry in a sealed bag (our suggestion, not the supplier’s). It comes in one size, listed as unisex, with adjustable straps.

The Honest Take

1. We have not tested it. No insulation, rain or fit test by us; everything about the product itself comes from the supplier’s listing.
2. The bladder is not confirmed. Nothing in the listing says one is included.
3. The listing disagrees with itself on rain. Its headline, its attribute list and two of its photos say waterproof; its description says both water-resistant and water-proof; its video says water-repellent; and its own specification table says water-repellent fabric with a non-waterproof zipper. We go by the table.
4. Two weights. About 317 g in the attributes and specification table, about 320 g on two supplier photos, and 0.6 kg packed. We have not weighed one.
5. Several details are missing. No bladder size, no insulation figures, no torso length or strap range, no certification and no warranty term for customers.

Specifications

Who It Suits, and Who Should Skip It

It suits riders who want water on their back for longer rides and trail days, who already own a bladder or plan to buy one, and who like a phone and snacks within reach on the straps. For the bikes behind those rides, see our electric mountain bike guide and long-range eBike guide. Skip it if you would rather carry water on the bike: the West Biking side-entry bottle cages or our handlebar cup and bottle holder keep the weight off your back, and the 4.5 L insulated handlebar bag moves snacks and a phone to the bars. Our eBike safety guide covers the rest of a riding set-up.

Frequently Asked Questions

Does it come with a water bladder?

The listing does not say it does. Its photos show a drinking tube in use, and its diagram has inner hook straps “to secure hydration bladder”, but no part of the listing, its specification table or its video lists a bladder as included. Plan on using your own unless we confirm otherwise; call 1-866-938-7580 and we will check before you order.

Is it waterproof?

Not by the supplier’s own specification table, which lists water-repellent fabric and a non-waterproof zipper. The listing’s headline, attribute list and two of its photos say waterproof, its description says both water-resistant and water-proof, and its video says water-repellent; we go by the table. In steady rain, our suggestion is to keep a phone or anything that must stay dry in a sealed bag inside.

Will the bladder compartment keep my water cold, or stop it freezing in winter?

We have not tested it, and the listing gives no temperature or time figure. The supplier describes a dual insulation layer for “Winter Warmth & Summer Cool”, and its photo shows a foil-lined compartment. Whether it keeps a drinking tube from freezing on a Canadian winter ride is untested, so we will not promise it.

What size of bladder fits?

The listing does not give one. The pack measures about 25 × 6 × 47 cm by the supplier’s hand measurement, which it says can be off by 1–3 cm. Compare your bladder’s flat size with that before you order, or call 1-866-938-7580 first.

Where do my phone and keys go?

The supplier lists a storage layer with compartment dividers, side storage pockets, and two pockets on the shoulder straps that it says can store “energy supplies and mobile phones”. Its back-view diagram also shows an attachment loop for small items on the reflective strips. We have not checked which phone sizes fit the strap pockets.

Will it fit me?

It comes in one size, listed as unisex, with adjustable straps, and the supplier’s photos show two buckled straps across the front. The listing gives no torso length or strap range, so we cannot say how it sits on a particular build.

What if it is not right for me?

Unused, unopened items can be returned within 15 days of delivery, less a 15% restocking fee, and the buyer pays return shipping; the terms are in our refund policy. If we ship the wrong item, or it is materially not as described, we pay the return shipping and no restocking fee applies. We have not confirmed a manufacturer warranty term for this backpack, so we state none.
