The Osprey Skarab 18 is a standout among hydration packs for its unique blend of features and functionality. Built with a medium size frame, this pack is the perfect companion for your off-road or on-trail adventures.

The first thing you'll notice about the Skarab 18 is its sleek, streamlined design. It's built to sit close to your body, reducing the chance of throwing off your balance, but has enough capacity (18 liters) to carry all the essentials for a day trip. The aesthetics are pleasing and the pack comes in several color options.

Regarding comfort, the padded back panel and extra wide hip belt distribute weight evenly, reducing stress on your back and shoulders. Many users have mentioned how surprisingly comfortable the pack is, even when worn for extended periods. The breathable mesh on the back panel is also a favorite feature, which helps lessen sweating on long hikes.

The quality of the hydration bladder is also a standout feature. It has a 2.5-liter reservoir with a bite valve for easy sipping. The ease of use and durability of the hydration system has been highly praised by customers.

While the Skarab 18 shines in several aspects, it isn't without its detractors. Some users have mentioned that the pack's small pockets were a bit limiting for multiday treks, and they wished the drink tube was a tad longer. There have also been few gripes about the pack's zippers being a tad finicky.

Overall, the Osprey Skarab 18 appears to be a popular choice among outdoor enthusiasts who prize comfort, capacity and quality in a hydration pack. Its thoughtful design and reliable features have left a positive impression on most users.

The CamelBak Octane 18 is a favorite among many outdoor enthusiasts for several reasons. It offers a good balance between storage capacity and ease of carrying. With an 18-liter gear capacity, it provides ample space for your essentials on a day hike or a trail run. Additionally, its dual-wing belt offers enhanced support and optimizes fit.

One of the standout features of the Octane 18 is the hydration system, which has a capacity of 2 liters. The Crux reservoir delivers 20% more water per sip compared to other models, meaning you don't have to stop and drink as often. This hydration bladder also has a leak-proof cap and an ergonomic handle for easy refilling.

Customers do notice the thought-out design. There's a separate and easy-access pocket for storing smartphones – a nice touch for those who appreciate organization. It's quite comfortable too, thanks to the breathable 3D ventilated mesh back and shoulder straps which help to reduce sweat buildup, making it a great pack for hot climates.

However, not everything about the CamelBak Octane 18 is sing praises. Some buyers mention durability concerns. The material, while lightweight, is not the most robust and might not withstand rough handling over the long term. A few users also express discontent about the waist belt, stating it's not sufficiently padded and may cause discomfort during longer wears.

Another minor drawback is that the bladder compartment is relatively close to your back, which some users note can make you warm. On the plus side, it does keep the center of gravity close to your back, which makes for easier carrying.

Nevertheless, it's a hydration pack that has proven popular among hikers, bikers and runners alike for its functional design, impressive hydration system, and smart storage solutions.

The Osprey Syncro 12 hydration pack truly delivers in its promise of being a comprehensive solution for hikers and cyclists in need of easy hydration, and it comes packed with some impressive features that are hard to resist.

The pack shines in its design - not only is the pack reasonably compact and sleek, but it also boasts a ventilation system at the back, which is a godsend for hot and humid adventures. The AirSpeed ventilated back panel keeps the coverage minimal, allowing cool air to flow freely between the pack and your back.

In terms of storage, Osprey Syncro 12 has one main compartment which is large enough to house the included 2.5-litre hydration reservoir, plus a few extras like some food and a clothing layer. Aside from that, it also has a smaller front pocket for valuables, and some smartly placed external attachments for things like helmets and LED light attachments. While it might not fit everything you’d take for an overnight trip, for a day's adventure, the pack is surprisingly roomy.

The hydration system surpasses expectations - the water bladder is 100% BPA and PVC free and is easily accessible from the top zipper for refills, while a magnetic point on the chest strap holds the mouthpiece in place so it's always easily accessible. The hose is insulated to keep your water cool, even on hot days.

Some customers have mentioned that the water flow from the bite valve can be a bit limited, which isn't ideal when you're really thirsty. But on the upside, it doesn't leak at all, even when turned upside down or when the pack is full. The manufacturer also agrees, griping about the low flow rate is quite common in online reviews, but most find it outweighed by the pack’s other benefits.

Durability is another strong point of the Syncro 12. Manufactured with a strong nylon material, this pack is made to withstand wear and tear of the trail, and several users praised this pack's ability to withstand quite a beating.

As for comfort, the Osprey Syncro 12 is very comfortable to wear, even fully loaded, thanks to its cushioned, adjustable shoulder straps and hip belt. They’re designed to distribute weight evenly across the body, and many users have mentioned how unbelievably comfortable it is, even after continuous hours of wearing. But keep in mind, the pack tends to run a bit small, so those with a larger frame might find a perfect fit elusive. Overwhelmingly though, customers seem quite satisfied with their purchases and repeatedly mention the comfort and practicality of this pack.

Reasons to Buy

• Great value for money
• Impressive storage capacity
• Easy bladder filling
• Made of durable material

Reasons to Avoid

• May not be the best fit for everyone
• Cleaning can be tricky
• Lack of sleek design

When it comes to scoring some major bang for your buck, the Gregory Nano 18 H2O pulls it off like a pro. With its practical features and robust build, it doubles up as an affordable daypack for those quick backcountry jaunts and a hydration pack that takes care of the thirst factor on those sweat-dripping hikes.

The design is compact, a nifty 18-liter bag that doesn't compromise on space despite its size. Uncluttered, easy to maneuver around with, and pretty lightweight, it’s a shoe-in for those who prefer light packing but still want some room to spare for those extra trail goodies.

The included 3L hydration bladder is a valued component, conveniently tucked away in a separate pocket, and has a magnetic sternum strap attachment for the hydration hose - a little touch that users have appreciated for its easy-to-reach design.

The main storage compartment and various pockets, including a soft-touch lined one for glasses and electronics, have been well received in customer reviews. Space organization seems to be a strong suit for the Gregory Nano 18 H2O, with its ability to separate, secure, and easily access items on the go.

Meanwhile, the shoulder harness design gets a nod for comfortable weight distribution. But, it's not all applause here. A common gripe among some users has been the lack of a hip belt for additional support, something to take note of if you tend to pack heavy or venture on longer trips.

The packed-in rain cover has been handy and appreciated for those unexpected weather changes, making this pack a convenient option for variable weather conditions.

However, for those prioritizing extreme water resistance, some users have found it to be a little wanting, suggesting that it might not hold up as well in constant heavy downpours.

So, Gregory Nano 18 H2O – a solid player in the budget game with its thoughtful inclusions and comfortable wear. While it might not score in all categories, one thing that comes clear through online user reviews: it earns its stripes as a functional and value-for-money hydration pack on the market right now.

The CamelBak Powderhound 12 Hydration Pack is a common sight on the ski slopes, and for very good reasons. It's designed to make hydration on the go fuss-free, even when dashing down a mountain.

One exciting feature of this pack is its dual orientation of the hydration reservoir. The orientation favors both left and right-handed skiers, a small inclusion that undeniably enhances overall ease of use. It sports a 3-liter water reservoir, ample enough for even the thirstiest of adventurers. The bite valve on the CamelBak doesn't drip and offers a steady flow of water.

Focusing on the storage, the CamelBak Powderhound 12 offers a single compact storage compartment, which should be noted, isn't as large as some other packs on the market. However, users have said that it is still ample enough to store a day's necessities like sunglasses, sunscreen, snack and even an extra layer of clothing. It also features an external strap system for helmet or gear attachment.

Concerning comfortability, reviews show that the pack is comfortable to carry for extended periods without causing strain or discomfort. The padded straps and a back panel made from mesh to allow for airflow, add to the overall comfort.

Now, while the bag is a ski-specific hydration pack, it's got a fairly versatile nature. As per users' online reviews, the CamelBak Powderhound 12 also appears to be an excellent choice for hiking or mountain biking in both summer and winter conditions.

One area where some users have expressed dissatisfaction is the pack's limited color options, offering just two colors. If you're not too bothered about fashion, the color limitation should not cause much of an issue. Overall, the general consistency in positive feedback online makes it a compelling choice.
