Trail Cargo Shorts

Assos' Trail Cargo Shorts are built to survive seasons of all-mountain riding while providing a dialed fit thanks to its use of technical textiles. It'll keep you comfortable and well protected on the singletrack and its trailFit cut is roomy, yet forgoes excessive material at the crotch, helping prevent saddle snags. Additionally, the Trail Cargo is the ideal length and can be worn with or without pads.

Assos scrutinized other baggies on the market, carefully analyzing their panels, fasteners, webbing, and zippers and how they contribute to unnecessary weight and uncomfortable pedaling. It decided to go with a minimal approach and use its Type.OF11 adaptable textile for the primary panels. It’s an extremely durable and lightweight bi-stretch woven material that’s highly abrasion resistant, fast-drying, offers UPF50+ protection, and receives a DWR treatment to fend off rain and mud.

Its AZPtech (abdomZeroPressure) construction uses a soft and highly elastic material that helps improve the comfort and fit at the waist panel for a smooth, comfortable wrap without excessive, unnecessary pressure. You'll also notice that the circumference of the legs is more tapered than its competitors which helps increase pedaling comfort and reduces hang-ups on trail foliage and your saddle. Assos recommends pairing these with its Trail Liner Shorts for all-day comfort and support.

How to Measure:
For best results, take measurements over your underwear.
Measure around the widest part of your chest.
Bend to the side and measure around the place where your waist bends, keeping the tape a bit loose.

I'm a huge fan of the quality and fit of Assos gear, especially their shorts and bibs. Although primarily a roadie, these shorts fit like other Assos products in that they fit perfectly when you're in the saddle. I wear them with a set of traditional bibs underneath and am a happy MTB rider now. The best part is the waist band which is comfortable, doesn't slip and is mostly forgettable.. in the best possible way.

Favorite Shorts!

These things have been a game-changer for me. They are really light and the most comfortable riding shorts I currently own. Gone are the days of velcro tightening straps and fabric belts, these shorts come in a yoga pant style fit. Just pull them on and you are good to go. The elastic waistband is lined with rubber to ensure minimal slip. I ended up ordering the largest size possible to get a more trail style fit and while they are a little big around the waist they still stay put through all but the gnarliest descents. There are two zipper pockets with just enough space for a phone, your keys, and your nutrition. They are extremely light and water-resistant. I have worn them in temps ranging from 95 all the way down to 35-degree temps and they keep you cool when you want them too and help block the chilly wind when needed.

I've been lucky to have a few pair of Assos road bibs for years, but kept them tucked away for the big days like those fancy champagne glasses you have, just so nothing unforseen happens. After one ride on the Trail short (where I spend far more time than on the road), I took the opposite approach. I ride, ride, ride, rinse, repeat. The waistband fits like a really nice pair of Lululemon yoga shorts would with zero pinch points. The material is perfect for a riding shell on hot days and has plenty of stretch.

The real differentiator - like all things Assos they fit like that should when ON the bike. With that in mind the crotch sits a little high and tighter which is perfect to prevent snags on your saddle. I've never had shorts like this and now can't get used to riding without them.

The hip zippers are a little short, more narrow than the pocked itself, which drives me crazy. But they are well placed and do the job. Overall, if you want a short that actually rides different and better, try this.

Lightweight. Comfortable. Ergonomic. Go-to. What? That's right - these have become my go-to baggies. Assos? Yep. I've now logged a couple hundred miles+ of sweet singletrack in them, and I find myself reaching for these first and always.

The stretchy, seamless waistband paired with incredibly lightweight and breathable fabric is a win. The pockets, at first thought to be too inboard to properly hold a phone, are not -- my phone hangs perfectly at my thigh on one leg, and plenty of room for other provisions in the opposite pocket, all contained without flopping around.

These integrate perfectly with the Assos liner, which is pretty perfect.

Minor nit: I find the opening at the knee just a touch wider than necessary. If it was a bit more "tailored", it'd be perfect IMHO.
