Assos Trail Liner Bib Short - Men's


Trail Liner Bib Short

Focusing on rider comfort and protection, Assos' Trail Liner Bib Short checks all the boxes on performance-readiness for epic trail sessions. Designed to be worn under Assos's TRAIL Cargo short —but fitting under most trail baggies — the Liner Bib's Aerofit fabric seems rather ironic, however, its ventilation and high-stretch make it ideal for your flat-out trail sessions. Stow your provisions securely in the mesh Ramp Pockets that combat heat buildup and are also positioned high enough on the bibs to avoid sharing space with your outer-short's waistband. Deep breathing on the climbs, you'll likely appreciate the AZPtech waist construction that supports heavy movement without pinching.

Assos uses removable impactPads that are 8mm thick for added protection during flat-out practice sessions or if you don't quite know the route you're taking. Underneath is Assos' OFF-ROAD Liner EVO Insert variable density chamois that targets thickness at the rear, which they feel more appropriately accommodates up-right mountain bike riding positions. And silicone-free leg grippers hold tight while you focus on the ride.

  • Lightweight, trail-ready liner for all-mountain sessions
  • Aerofit warp-knit for ventilation and comfort
  • Removable impact padding for skills-practice sessions
  • Ventilated rear panel with secure pockets
  • Variable density chamois for ideal comfort

Seam in the wrong place

I returned this product before using it

Wanted to like these but they seamed them right up the middle in the front. So stupid on bib shorts meant for men. Chamois was a bit thick for my liking but the seam was the reason I returned them. Probably better off just buying a pair of their road bibs and foregoing the pockets.

These shorts are awesome. Top notch Assos quality in a lightweight short to wear under my baggies. The chamois is super comfortable, fit is perfect, and the pockets are a nice addition.

No hip pads

I've used it once or twice and have initial impressions
True to size

Description is a bait-and-switch. No hip pads come with. For the price that is nuts. And the hip pads are out of stock even if you wanted to buy them separately. Never buying Assos again.

Hummm...mine came with pads. They must of sent me yours just to tick you off.


Got one of these assos bibs. It dosnt come with removable protection pads. What is the part number for these pads
