The TREW Trewth Bib is a really solid pant for serious resort and backcountry skiers. It has fantastic breathability, solid waterproofing, and a load of backcountry and resort specific features.

TREW Trewth Bib Ski Pant Review

Tester: Matt

Pant Size: M

Matt’s Specs: Sizing Info

Waterproofing and Breathability: The TREW Trewth has a 3L 80D Dermizax NX waterproof and breathable fabric. The 80D fabric feels thick and durable and with a 20k waterproof rating, will do a pretty solid job keeping you dry in wet weather. It also does a really good job of blocking out wind. Despite its thick feel, Dermizax is highly breathable. At 40k, it’s the highest rated breathable fabric on the market, and I can say that it works pretty damn well. I didn’t feel like it was quite as exceptional as the 40D Dermizax NX of the Roam pant simply because it has a slightly thicker feel. Still, it’s definitely one of the most breathable pants I’ve used, and would be great for highly active skiers.

Fit and Feel: The TREW Trewth wasn’t quite as comfortable feeling as the Roam, but it still has a great feel. The 80D fabric feels tough and durable, but does sacrifice a bit more comfort. Still, with a soft base layer underneath, the Trewth feels perfectly fine. The Trewth is a full bib, and the fit is pretty good overall. I found the small to be just about the perfect size for me. The waist fit really well, and I had just a touch of extra room in the bib and legs for layers. The suspenders also allow me to tighten the fit and make it feel less droopy or baggy. Overall it feels roomy, without being loose, and I have plenty of articulation for mobility.

Warmth: The TREW Trewth is a 3L shell without insulation. It will give you a solid amount of protection from wind and rain, but definitely not warm without a good layer underneath. Still, the extra bib does give it a little extra warmth compared to a traditional pant, and with the right layers underneath can actually feel really warm.

Features: The TREW Trewth is loaded with all sorts of great features. First off, this thing has pockets everywhere. There are two mid-sized pockets on the chest, that would be a great spot for a radio or transceiver. Just below the waist are two hand-warming pockets. These are placed really well, and are actually quite large. Further down the leg are two more cargo pockets. These are quite deep, but do sit just at the knee so I’m not going to use those for anything hard. The bottom of the pant has a large kick patch to help resist tearing from boots. The inside of the hem also has a boot gaiter to help keep snow out of the bottom of the pant. There are not vents on the inside of the pant, but two extremely large ones on the outside. Both double as an “easy entry” for the bib, but work perfectly to cool you down in a hurry. They run from above the waist to just about the knee, and have multiple zippers to better customize air flow in and out.

Bottom Line: The TREW Trewth is a very solid backcountry pant with high tech fabric and loaded with great features. It has a thick and durable feel that should hold up to abuse pretty well. You could use this as a resort pant as well, but may be overkill for a lot of areas.
