Functionality
The built-in cinch belt is flat and slim-line enough that you can wear your own belt as well- perfect if you want to carry extra gear on your belt. The bottoms can roll up quite neatly and stay there, thanks to a snap on the side. The front and back pockets are placed nicely and big enough to use comfortably, unlike many pockets you see on men’s hiking pants (as well as women’s, which have notoriously useless pockets).

Comfort and Weight
The PrAna Stretch Zion are as comfortable as they look. Their fit is roomy enough that they’ll accommodate a set of long underwear/thermals underneath, but slim enough that a waterproof shell (like the Marmot PreCip below) will fit over the top without any issues. These are not the lightest pants reviewed here, but at 13 ounces they’re still easily less than a pound making them a great choice if weight is important to you.

Functionality
Breathability is very good, the very light material helps you stay cool, the waist system is interesting and comes as integrated and works in conjunction with a web belt/the buckle is plastic and features as a standard-sized belt.

Comfort and Weight
Due to the thin lightweight material used in the making of the pants, it is not recommended to use them for any outdoor activities where the pants are subjected to high abrasion from activities such as rock climbing. These are very light to wear, breath-ability is nice and the factor for performance is good while hiking in mild, warm or reasonably hot environments. If you stay true to the purpose of the design you will get good performance, comfort, and a level of protection

Functionality
Often, hiking pants fall into one of two categories: waterproof, terrain resistant, insulated and breathable, covered in technical zips (and alarmingly expensive); or basically a pair of everyday slacks that dry a little faster and weigh slightly less.

In the Fjällräven Keb, we think we’ve found the perfect balance. The upper, front of the pants and the panels behind each knee are made from a polyester/elastin blend. These sections are stretchy and durable, but soft and breathable too. The rest of the Keb: the front of your thighs and knees; the whole backside; and the bases of the trousers (where you get the most abrasion and tangling and hill-sliding); are all made of a 65% polyester/35% cotton blend Fjällräven call G-1000.

Comfort and Weight
If you’re worried that these panels sound heavy and impermeable, fear not: we were quite impressed by the ventilation zips that run down the side of each. This makes pants that are the best choice for hiking pants for cold, wet weather and rough terrain perfectly good choices for hot, muggy days as well.

The ankle cuffs of the pants are designed to be worn in about four different ways and sit really well in each position thanks to the snap fasteners. This means that no matter what your body shape (height/waistline), what shoes you’re wearing, or whether it’s hot and sunny or blowing freezing rain on you, you can close the ends of the pants up in a way that’s satisfactory.

Functionality
Made of nylon and spandex and featuring articulated knees, these pants are mobile and allow for full freedom of movement. The fabric itself is quite tear-resistant, so they're definitely built to last. They aren't terribly water resistant despite having a DWR coating, so these may not be ideal for anything more than light rains. A zippered pocket on the thigh is made to easily fit a phone or wallet. The legs aren't convertible into shorts, but they can be rolled up to a more Capri-style length.

Comfort and Weight
At twelve ounces, these aren't the lightest of pants, but that makes them work well in colder conditions as well. The fabric is soft and flexible, allowing for a full range of motion no matter what you're doing. Internal drawstring lets you adjust the waistband without the need for a belt. The fit is stylish and feminine with a mid-rise waist and runs true to size.

Functionality
Way up in the top league for stretch capability, you get great mobility without restriction, these pants stretch when needed so they are comfortable with your body motions. On cool days you feel comfortable and on hot warm days the comfort level is consistent, due to the thin material you would be wise not to use these hiking pants in extremely cold conditions, they were not designed for extreme weather.

Comfort and Weight
Built from light material and DWR coated for weather protection, the pants are comfortable for hiking and you won't feel a sensation of heavy material weight. For durability, the pants are well constructed and you won't experience seam failure, if you use these pants true to purpose which is hiking, your going to get longevity, good performance, and sound durability but if you take these pants into activities such as climbing rock faces then you need to accept that durability will be challenged.

Functionality:
Made of nylon and spandex, these hiking pants have a DuPont Teflon coating to keep the moisture out and the warmth in. Ten (that's right, ten) pockets ensure you'll have enough room for whatever you bring with you.

Comfort and Weight:
The fly is secured at the waist with velcro closure, allowing for the same comfort and security as a button closure, without the chance of it digging into you when bending over. These pants have fully articulated knees, and internal compartments for knee pads in the event you need them. They are on the heavier side, and thus may not be well suited for warmer weather. A gusseted crotch allows for better freedom of movement while making them more durable by reducing the amount of stress put on the seams.
