Best Gusseted pants available!
August 23, 2013

After wearing Gramicci's for years and years, for the comfort and versatility of a gusseted crotch, I discovered these, and they have become my favorites for biking to work, being at work, and everything else. Highly recommended! Glad to see they will be available next year in dark gray instead of dark green; goes with more of my shirts and jackets.

Pros: Great design, comfortable!, lightweight

Really Tough Pants
October 16, 2013

I've had this pants for over a month and have worn them very frequently because of the fit and comfort-ability. They are really a great pant!! Also, I've used them hiking and they were light and extremely durable. I've read that some people think they are a bit cut to close at the ankles but not for me, they taper off quite well and give me room where it's needed. The price was right and of course Altrec had them here in no time. Very pleased with this item as usual!!

Pros: Great design, Build quality, Lasts forever, Performance

a good summer hiking pants
September 29, 2012

The pants is very light and thin. Thus it's only good for summer, early fall, and late spring season. For a 30"-31" waist, size M is perfect. However if your waist size is larger, you will need a larger size. The adjustable built in waist belt is very flimsy. I'm not sure if it's 100% effective, but luckily I don't need to use the belt. The back pocket and the thigh pocket have zipper, but they are small. In fact all the pockets are small. It's OK for a hiking pants, but if you need a pant with deep pockets for foreign travel, you will not like this pants for the two front pockets do not have zipper, are very small and shallow. I suspect that things will be accidentally drop out when sitting down, although it has not yet happened so far because I avoided using them. The pant fabric is very thin. I have a grey dark color pants and it provides better privacy protection. I think the khaki color pants can be easily see through when it's wet.

Pros: Ease of use, Cons: small shallow pockets., flimsy waist belt

My new favorite pants
June 18, 2012

I had to replace some older TNF and Exoficcio pants so I decide to try these. I love them. I thought I would miss the inner mesh from my Exo pants and I was concerned that this model didn't have it but they are still comfy. Just did the Grand Canyon down the seldom hiked Hermit Tail to the river and these pants were great! The built in belt is great too.

Pros: Great design, Build quality, belt

Update of GI pants
April 02, 2012

This is an update of the GI II pants which I have worn hiking for several years. The GI pants are great in terms of ventilation and mobility. I remain cool in these even when hiking on hot days and they do not show normal abrasions. The GI III has a new fabric which is softer and drapes well. The downside to the new model is that the pockets are smaller and the front pockets place the contents more on the front of the pant than at the side.

Pros: Build quality, Performance, Ease of use
Comfort: 4 / 5

Great pants
April 05, 2012

Patagonia is all about quality. Great pair of pants for hiking. It is nice that Altrec has the hard to find sizes. Altrec also helped me out with my return. Excellent company to purchase hiking equipment from. I am sure to purcase again. I am eyeing the Gi III shorts in that awesome Alpha Green color.

Pros: Great design, Build quality, Ease of use, Great value, Lasts forever, Performance

change is... different
May 07, 2012

As a big fan of the Gi II in its various forms, I was curious about these. Overall the waist and length have the same proper fit as described but the legs are cut more slimly now. They are not at all baggy in the waist or seat which is neiher good nor bad, just different. They are not so slim as to restrict movement, just slimmer. Also it feels like the material is thinner and may be more readily torn than the predecessor. All other details seem unchanged.

Pros: Great design, Build quality, Cons: Cost
