Reviews & Tips
1. Next-generation chamois with gel inserts in the ischiatric area provides targeted pressure relief where it matters most during long saddle sections
2. Bi-elastic recycled polyamide padding fabric (78% recycled polyamide, 22% elastane) combines sustainability credentials with quick-drying softness against the skin
3. Ergonomic compression fit improves anatomical performance and holds the chamois in the correct position throughout long rides
1. Inner shorts are an additional item over outer shorts, adding cost to the kit setup compared to integrated chamois shorts
2. Boxer style design and elasticated waistband may not hold as precisely as a snap-and-adjust outer short closure for some riders
3. These are a specific product for riders committed to the outer-short-plus-liner system, which requires an appropriate outer short to pair with
Saddle comfort is one of the details that separates an enjoyable long trail day from an uncomfortable one, and the Alpinestars Alps Inner Shorts address that directly with a purpose-built chamois liner engineered for mountain bike use. Worn beneath outer trail shorts, they bring a level of saddle comfort and anatomical support that outer shorts with basic integrated liners typically can’t match.
The main chassis is constructed from an advanced, quick-drying polyamide-based stretch fabric that combines strength and durability with effective moisture management. Polyamide construction provides the durability that inner shorts need for repeated use and washing, while the stretch properties allow the ergonomic compression fit to work without restriction. Moisture is drawn away from the skin effectively, keeping the contact surface between rider and chamois as comfortable as possible during sustained efforts.
The chamois itself is Alpinestars’ next-generation design, incorporating gel inserts in the ischiatric area — the sit bones — where pressure accumulates during extended saddle time. The gel is rooted directly in the foam rather than sitting on top, providing integrated support that doesn’t shift position during movement. The bi-elastic padding fabric is constructed from 78% recycled polyamide and 22% elastane, giving it a soft feel against the skin, quick-drying properties, and a sustainability story that reflects Alpinestars’ commitment to recycled materials across their range. The top layer of the chamois is specifically constructed with recycled fabric to prevent chafing.
The boxer-style design features a supple elasticated waistband that maintains the correct anatomical position of the shorts throughout riding, and the ergonomic compression fit keeps the chamois working optimally regardless of body position changes.
The Alps Inner Shorts suit MTB riders who run the outer short plus chamois liner system and want the most comfortable chamois liner Alpinestars make. They’re particularly relevant for enduro riders on longer stages, trail riders who cover significant distances in a day, and any rider who has found integrated outer-short chamois insufficient for their saddle time requirements. They pair directly with the Denali Shorts and other Alpinestars outer MTB shorts that include a flat-snap connection system.

The Alps Inner Shorts deliver targeted saddle comfort engineering at £79.99. The recycled-fabric chamois with ischiatric gel inserts, quick-dry polyamide chassis, and compression fit all contribute to a chamois liner that performs across long days in the saddle.
The Alps Inner Shorts are a well-engineered chamois liner that earns its place in a serious MTB kit setup. The next-generation chamois with recycled padding and gel ischiatric inserts delivers genuine comfort on longer saddle sections, and the polyamide quick-dry construction means they hold up across back-to-back riding days. A strong pairing for the A-Dura Shorts or any trail short without integrated padding.
