When it comes to our clothing, we use two types of sizing systems: a familiar letter sizing (XS, S, ..., XXL) and a combination of a number and letter (XS-42, S-44, S-46, ..., XXL-60).

The first type of sizing is familiar and easy to understand. The latter type is how we adapt the European numeric sizing to the American letter system.

Let's take a look at mens sizes 46, 48 and 50. Size 46 is close to a Small and so became S-46. Size 50 matches well to a standard M and so became a M-50. But size 48 sits in the middle. We decided to label 48 also a medium - M-48, but you should think of it as smaller medium. 

Please refer to the them for measurements.

Fit

Besides the core dimensions of each size (see the sizing tables above) there are variations to the cut of each garment depending on whether it is designed for one of four fit types: Expedition, Regular, Alpine, or Athletic. 

Expedition Fit: Loose

  • Cut roomy enough to allow for a layer beneath, even multiple layers under an exterior layer, without restricting movement
  • The fit is neither loose nor tight, garment follows body contours but does not restrict movement
  • Extended torso for extra warmth; harness fits over garment
  • High and wide colar

Regular Fit: Roomy

  • Constructed for less technical use and lower-cardio outdoor activities in all seasons
  • The fit is loose, universally appropriate for any figure
  • Length: long torso, based on fashion trends

Alpine Fit: Close

  • Cut to minimize excess bulk even with multiple layers. Crafty construction at key joints - gusseted crotch and armpits, articulated knees and elbows - allows the greatest range of motion with each fabric
  • A close fit that follows body contours without restricting movement.
  • Length: a short torso; to be worn over a harness
  • Collar: high

Athletic Fit: Tight

  • A tight cut with stretch brings prevents fabric bunching and helps draw sweat away from the body to accelerate drying time.
  • Articulated knees and elbows allow a wide range of motion.
  • The fit is skin tight with elasticity to enhance muscle support with base layers or block wind on outer layers.
  • Length: a short front with a longer back for easy harness adjustments or to cover the lower back when riding a bike.
  • Collar: medium height, slim fit, unrestricted head movement

Excellent pants!

I'm an avid backpacker who backpacks in the USA and in other countries. I love these pants! They're moisture-wicking, lightweight and comfortable. They're also attractive. I can hike for the day, and then come back to the city I'm visiting and fit in with the business crowd. Very nice! These pants are of high-quality and keeps you cool in the summer. I highly recommend these pants!

Great!

Warm and comfortable baselayer. It could be used as a mid layer at cold temperatures. I really like the power stretch things. Regarding sizes, I am 6’0’’ and fit, I got L52 , it fits perfect

The price is so high. Bang for the buck! The price must come down to $70.00.

Great buy

Great durable bag

great pack

I bought this 3 years ago, it's been all over the world with me. Very happy with it! It's still looking pretty new after 3 years. The many compartments are very useful and convenient for finding your stuff. the hard back is great for carrying my laptop and external keyboard and there is separate pocket for them as well which helps the main compartment be more organized. The only downside is that the water bottle pockets on the side don't security hold a big water bottle, for me it would be better if they were taller, the strap above the pockets can lock in a taller water bottle but it doesn't work perfectly, sometimes the bottle falls out. Nevertheless very satisfied with this pack and recommend it.
