Sizing Notes
Measurements are stated in inches unless otherwise indicated. Size chart values represent body measurements, not garment measurements.
SHORT: Some pants are available in short sizes, which generally means an inseam that is 2.5 inches shorter than regular sizes.
TALL: Some pants, shirts, jackets and parkas are available in tall sizes, which generally means an inseam that is 3 inches longer and a rise that is 1 inch longer, a shirt or jacket body that is 2 inches longer, a parka body that is 2.5 inches longer and sleeves that are 2.5 inches longer than regular sizes.
Capri or cropped pants have an intentionally shorter inseam—reference the technical specs instead of this chart.

Solid shorts
Very light, easy to move in, decently elastic, comfortable waistband, no itchy tags or threads, very soft and non-chafing. I only bought two and until I buy more, what I love most is even if I recycle them through a second or third run, they don't smell as long as you let them air dry. Not that I encourage you to run through dirty shorts, but they're very anti-odor. Only critiques are small back pockets, no side pockets, and the brief liner doesn't secure the "goods" as much as I'd like. Maybe not quite worth 60 bucks so glad I got them on sale for around 40-45. Still, better value and comfort than the Patagonia running shorts in my opinion.
Wanted to love these
I want to love these, but the liner is kind of ruining it for me. These are great shorts in almost everyway, love the fit, love the waist band, love the pockets, especially the increased size of the rear one (from previous generation). My only problem, and it's a bit of a big one, is the liner. The brief style is not it for me. I'm always mildly aware of it, it always feels like my...stuff...is about to come out, it's just not great. If it had more of a boxer brief style like the 7" I would be majorly in love with these shorts.
Light, Fast, and Ready to Move
Light, Fast, and Ready to Move – The Perfect Running Shorts The REI Co-op Swiftland 5” Running Shorts are exactly what I’ve been looking for—no fuss, no bounce, just performance. The sizing was spot on (medium fit like a glove), and right out of the gate they felt incredibly lightweight and comfortable. Whether I’m hitting the trail or pounding pavement, these shorts stay put and never ride up. The material breathes well, dries quickly, and has just the right amount of give for those uphill scrambles or longer efforts where comfort matters most. The real surprise? The back pocket. It’s discreet but surprisingly spacious—fits my iPhone securely without that annoying flopping around you get in lesser designs. I’ve worn these in the thick Florida heat, and they’ve held up beautifully—no chafing, no soggy mess, just reliable, high-performance comfort. These shorts feel like they were made by runners, for runners. If you’re serious about your gear, these deserve a spot in your drawer—and probably a second pair in your cart.
Not a fan of the brief style liner
Bought multiple pairs before they changed the liner to a brief style liner from the original compressions short style liner. Not a fan of the new liner as much. Definitely preferred the compression liner underneath. Overall great shorts with good zip pocket on the back.
Light running shorts
I just received these and went for a 5 mile tempo run. These shorts are so light and airy, it's like wearing nothing. These are my new warm/hot weather shorts and my marathon race shorts. I'll be buying more.
Need better liner
Need to improve the lining on these. The 7" version is designed much better. Everything else is great but had to return because the support was so poor.
Very well designed shorts.
I’m very impressed with the design and thoughtfulness that went into these shorts I love having small pockets for keys AirPods and phone. Also the fabric is super airy and comfortable. I would typically run with a 7 inch inseam but I really like these.
Liner is not good
The liner on these need some improvement. My boys feel like they’re going to spill out. Probably will return them.
Great running short at a fair price
These shorts are very lightweight, fit well, the fabric is very soft and the pockets and seams are well made.
Just don't fit
Really tight in the waist but baggy in the body. Way too long for the description.
