OVERVIEW: Durable, hard-wearing fabrics in the Terrain Collection of garments provide the breathability and protection you’ve come to expect from a trail kit designed for the love of speed. 

FABRICS: The tenacious, 4-way elasticity of StretchForce fabric provides the flexibility, movement and durability necessary for navigating each trail’s obstacles. A stretch-knit, Nylon panel has been set-in to the upper-back of the short, providing both breathability and extra stretch where you need it most in the short.


  • The on-bike fit is articulated for riding position, and incorporates a durable, stretch-knit panel for increased comfort while getting way off the back in steep terrain.
  • A tapered (higher in the back) waist band provides plenty of coverage in riding position and is lined around the back half of the short with gripper to ensure the short stays locked in place while riding.
  • The waistband is fitted and has a large elastic “belt”, utilizing hook and webbing to dial in fit. A dual button and zip-fly provide a secure closure.
  • New for 2020, a dual-direction leg-zip system brings 3 distinct features to the short. When zipped up from the leg opening, a mesh gusset is revealed allowing up to 7cm of extra circumference to accommodate pads or personal preference. This mesh gusset also serves to ventilate on hot days. When the top zipper pull is zipped down, it reveals a backward-facing pocket, perfect for cards, keys, small tools or any other items you want secured.


  • 4-way stretch StretchForce fabric (93% nylon, 7% spandex)
  • PMD leg opening closure system
  • Internal fit system
  • Contoured on the bike fit
  • YKK zipper rear and front pockets for pedal-friendly storage
  • YKK zipper front fly
  • Double offset button opening
  • Tall rear waist panel
  • 14” inseam (size medium)

Measuring Tips 


Using a soft measuring tape, bring the tape across your back under each arm, around the front. For women, measure the widest point of the bust. For men, measure around the largest part of your chest.


Bend to one side to find natural indentation in torso. This is your natural waist. Run tape around waistline, keeping tape parallel with floor. 


Stand on a level surface with feet together. Measure around fullest part of hips and bottom (approximately 7" - 9" below waistline), keeping tape parallel with floor.

Great shorts!

Not baggy! Love that. These are really durable and you get what you pay for. Living in the high desert where sun, sand, and pokey things are. Technical gear is critical and items that last the test of time are too. Well done Pactimo, Well done.

Great shorts -- watch sizing

I really like these shorts. Fabric is nice, pockets in the right places. Like the vents, etc. IF you can get them on sale, it's a deal. However, as others have mentioned, they seem to run a bit toward the small end of the listed size range. For reference, I'm a 32 waist with hips a little wider than average and I wouldn't want the M I ordered to be any smaller.

Disappointed with your customer appreciation

Yes I bought this short in blue, and would have been my second short of this model. Though, after waiting for my order and with great dissatisfaction I have received the OLD VERSION OF THIS SHORT being ordered the new version which the one currently in the website. I have contacted the CS and let them know about the wrong item delivered. Up to this point all was manageable since I have requested the replacement of this item. The request was accepted and it supposed that I would receive the right one soon. A week later I received an email saying “we are sorry” but we do not have this item in stock anymore which was two days after they received the returned item. As your customer and big fan of yours I did not feel appreciated... probably I have not bought enough..

Mostly good but they seem to slip down a lot

They are the typical high quality I expect from Pactimo. I like these shorts but they tend to slip down. I ordered according to the size chart but I’ve had to adjust them to the minimum size and they still slip down. My guess is they would fit fine if I ordered the smaller size down but as they are I have to stop periodically and hike them up.

Great shorts . had to buy a second pair...

The Pactimo Terrain shorts are great. They are comfortable, have good flexibility, and are very durable. The material is breathable but does give a layer of wind protection which is nice. An all around great mountain biking short.

Great Design - Love the Style!

Just starting to get into mountain biking and this was my first apparel purchase. Great design, great fit!

Heavy Duty Shorts

These shorts fit great and are very well thought out. The waistband is the best yet and stays put over bibs while climbing. My only gripe in hot weather is that the material is heavy duty and thick... that being said, it does feel like durable material that will hold up if you crash in these...

Great riding shorts for Gravel and MTB

Comfortable. Properly sized and practical. Very well made

Tough comfortable adjustable good zips

These are very solid. The waist adjustability is great and much more durable than velcro I think. I couldn’t imagine wanting the venting gussets until I tried them—they are awesome for comfort and cooling on long ascents.

Terrain Shorts Men's

These are very comfortable mountain biking shorts. I like the zippered pockets on the sides, easy to reach for my phone while keeping it secure while riding. I was riding with two others and they liked them too and are going to buy a pair for themselves.
