sustainability

Groundwork Knit is made using a premium grade nylon that has a significantly tighter woven filament than standard synthetics. Tighter filaments mean less microfiber shedding in the wash-cycle, plus greater durability of the garment (longer lifespan, more wearing).

Groundwork Knit fabric is also bluesign® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

Two thumbs up

I grabbed a pair of these during the REI anniversary sale just on a whim. I didn't need more tight shorts, but I get tired of 7 inch shorts. THESE ARE SO GOOD. Don't change anything about these. I'm kicking myself for missing out on the Batik pair.

The only thing I will say is this: the fabric is thin, so if you're a heavy sweater like me, it will look like you wet your pants. Even in the black. But since they dry quickly, I don't mind.

Groundwork Trail Short

These shorts are lightweight with just the right amount of compression. The deep pockets are a plus.

Stays in place, seam colors on black pair look better in person

I have the groundwork short tight and adore them, but I wanted a shorter pair for the summer. I was hesitant to get these because frankly I thought the seam colors looked stupid (I just wanted plain colors…). Anyway, I figured I was running in them so looks aren’t a big deal and I got the black pair with the blue seams. Looks way less weird (to me) in person with the bright blue seams.

Aside from that, they are super comfortable, stay in place and hold my iPhone SE (normal sized phone) beautifully. So much so that, similar to my groundwork short tights, at least once a run I will have a brief panic because I thought I lost my phone because I literally forget that it’s there. They’re that good at holding a phone - even tbkjbbr they’re pretty short. There is a nice little key clip in one of the two generous pockets on the legs which is nice, though I have yet to use it.

My only recommendation going forward would be to make this in the regular colors (ie leave the seam color alone and have it match the color of the short).

I have a pair of rabbit shorts also (leggy something), and they don’t hold a light to the quality of my Janji ones in terms of materials and fit.

My new favorite running short

Perfect inseam. I was worried it might be too short but the riding up in the crotch is minimal thanks to a sticky inner seam and the short end. So many awesome pockets and a key ring to keep my car key secure. Lightweight, perfect for warm sweaty workouts. Rise is perfect. I have a long torso so it comes up to just under my belly button. They do not fall down and have a draw cord just in case. I’m usually a side 6 or 8, between an Athleta S and M or a 6, I have wide hips and a smaller waistline, and the medium in this short is perfect.

Im in between sizes. First tried xs then exchanged for small. Perfect fit. Exchange process was seamless. I used the groundwork trail shorts for half marathon on Sunday. It was in the high 80s. The material was very light. Carried my phone and inhaler and they stayed in place the whole time. Great pair of shorts!

Absolutely love!

These shorts are super cute and functional great for those long runs! Even better is they don't ride up when running! I have never felt this great about this style on running shorts before! Love them so much that I bought another 2 pairs!

Groundwork trail shorts

I purchased both lengths of the groundworks trail short - I love the batik print and beautiful colors! I am in between sizes, so I tried the small but ended up going with a medium. They are light weight, tons of pockets, don’t ride up and overall feel very free and great to run in. A great minimalist short.

Love these, but…

I think these shorts are amazing. You can never have too many pockets for snacks on long adventures. What would put them over the top would be a crotch gusset so they could be worn without undies to minimise chaffing. You could call it the Run Free Trail Short:)
