Conor R.wrote a review of Arc'teryx I340a Harness - Men's on February 18, 2012
I've tried other harnesses out there, but in the end I keep coming back to Arc'teryx. In my opinion there is no better combination of lightweight, comfort and functionality than the new I340a harness.
Arc'teryx has fixed the lack of drop-down leg loops and added ice clipper slots that were lacking on the X350a harness, and have actually managed to shed some weight too.
The WARP technology keeps this harness so light and packable, yet surprisingly comfortable while hanging or belaying.
While a bit pricey, in my opinion, for Year Round climbers, there is no better one-quiver harness out there on the market.
