Bought this&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Columbia-Men-s-Cougar-Peaks-II-Jacket/dp/B001KBZ30U/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Columbia Men's Cougar Peaks II Jacket</a>&nbsp;in charcoal, as it seemed to be a decent three-season garment that would offer some protection from the elements. The main purposes for this jacket were for general wear, cycling in questionable weather, and as a jacket that could stow away comfortably and in a compact fashion so that I could stuff it into a camera bag for those occasions when an unexpected shower might hit.

Let's clear up one thing to start: I did not expect this lightweight jacket to be waterproof. That said, I did treat the inside seams with a seam sealer withing a few weeks after receiving it. Try&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/McNett-Seam-Sealer/dp/B000O71L6Q/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">McNett Seam Sealer</a>&nbsp;or some similar products, but be sure that (1) you apply it to the inside seams only, and (2) that your product will work with nylon. If you're looking for a truly waterproof jacket, if there's such a thing, then look elsewhere. This one is water resistant, regardless of what might be claimed on some sites.

Pros:

* Extremely lightweight
* Machine washable (cold only)
* Decent stowaway hood in the collar
* Good main sipper that doesn't jam
* Pocket zippers close up - things less likely to fall out
* Adjustable elastic drawcord at the hem
* Rational styling, and the "Columbia" logo doesn't scream at you

Cons:

* Back shoulder vent cannot be closed when it's windy
* No armpit vents; not very breathable
* Seems to trap condensation

If you want to stay really dry, then look at the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Columbia-Men-s-Watertight-Jacket/dp/B00365F9G6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Columbia Men's Watertight Jacket</a>&nbsp;or the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Carhartt-Men-s-Waterproof-Breathable-Acadia-Jacket/dp/B003OQUJJE/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Carhartt Men's Waterproof Breathable Acadia Jacket</a>. These are examples, but you'll spend more than this one.

All things considered, didn't expect much for the price when I ordered it, but it's a fairly decent lightweight windbreaker that doesn't have much bulk, so it can be stowed away when necessary. If this is what you're looking for, then it's worth it.
