Measurment Guide


Measure around the middle of your neck (at Adam's apple), keeping tape a bit loose.


Measure under your arms, around at the fullest part of your chest. Be sure to go over your sholder blades.


Hold the tape at the center back of your neck, measure across your sholder to your elbow, and down to your wrist. The total length is your sleeve length.


Using a pair of pants that fit you well, measure from the crotch seam to hem line. Round the number to the nearest 1/2" to get your inseam length.

Travel pants for day and evening

Great cut and fit. I’ll let you know more after traveling for a month in Italy. I am a tour guide.

Love the lack of flaps!!!

I'm tired of pockets with flaps. When I found these without flaps but with the side pocket I ordered three pair. When they arrived I was pleasantly surprised to find all the pockets (except the front, of course) had zippers. Made my day. I also like the fact they are lightweight and have some stretch to them. Thank you Union Bay.

Great Product- Even better Customer Support

I recently purchased three pairs. After arriving a few days since the order, I performed a cursory inspection where I did not notice any issues. About a week later I put a pair on to observe that a belt loop was missing on the right side. Ordinarily not an issue, I wear a case on the right side with my phone and was concerned that over time the other loops would fail. So I called Unionbay to request a replacement and a shipping label for return of the defective pants. They informed me that they would send out a replacement and to keep the defective pair. Amazingly the replacement arrived on the East Coast a day and a half later! The pants are great. Extremely comfortable, light, and cool for walking. I had bought 1 pair a while back at Costco and only regret i had not bought more. Far and Away my favorite pants.

Great pants!

Light-weight and fit as sized. After buying one pair in a store, and not finding black at the store and being very pleased with them, I decided to order on line. Very glad I did. Comfortable and more so with the stretch waist band.
