Description

These Primaloft trousers/pants are now also available in custom sizesSpecify Waist and Inside Leg sizes independently to order made-to-measure synthetic-insulated trousers/pants. This tailor-made service can cope with sizes from XXXS to XXXL and is ideal if your waist to inside leg ratio differs from standard, ready-to-wear patterns. 


With a combination of synthetic insulation (Primaloft Gold®), our lightweight MX fabric, and a light and simple design, these synthetic-filled trousers are the perfect choice when it's going to be cold and damp.

In our experience the Primaloft Gold® synthetic insulation absorbs water much more slowly than other synthetic waddings, a marked advantage in cold, wet conditions.

Please note: If you order a custom-sized version of these Primaloft trousers they will take longer (approximately 45 days) to be manufactured ready for dispatch. Custom-sized versions of these synthetic-insulated trousers are not returnable and customer loyalty discount cannot be applied.

Technical

Superlight MX fabric (weight: 32 gsm)

A mini-ripstop nylon with excellent tear strength, MX is the pick of the superfine 15 denier downproof materials. We have tested lighter fabrics, but most have had significant drawbacks, while our confidence in MX is based on several years of extensive use in both our ultralight and our high mountain gear.

Primaloft Gold®

Primaloft Gold® is the ideal microfibre insulation. Ultrafine fibres produce an insulating core that is incredibly soft, lightweight and water resistant. In our experience it absorbs water much more slowly than other waddings, a marked advantage in wet-cold conditions.

The nearest of the synthetics to the feel of down, yet tougher than you would expect. Primaloft Gold® offers the best warmth/weight performance in the Primaloft range

Reviews

"I put them on and instantly felt the warmth they provide. They seem so brilliantly designed and manufactured. One of the reasons I keep coming back to PHD gear is that I know it's made in the UK and that it's made exceptionally well."
Rob Stretch

"Probably my cold weather 'gear of the year', if you pair these insulated trousers with ... a winter jacket ... you'll be set up for whatever the season ahead throws at you. I have insulated alpine pants that are 3 times the weight and less warm than these. For me, synthetic insulation is a better choice than down in more cold weather conditions, as they are much more likely to get damp at the knees, seat and ankles. These are insanely warm, disperse moisture rapidly and scrunch down tiny. Serious clobber for serious conditions. I am genuinely impressed."
