The Peak Oyl Mtn is No Longer AvailableThe Peak Oyl Mtn Women's takes traditional self-inflating foam pad design to the next level with its air core rails. These help shave weight and keep you in place at night. The pad has 1.5" of soft, diamond die-cut foam that keeps you comfy and warm even when the temps drop below freezing. Unfortunately, the Peak Oyl Mtn is neither the lightest nor most packable pad in its class. The pad weighs a hefty 24 ounces. Though slightly less comfortable and less warm, the Therm-a-Rest ProLite - Women's is our favorite self-inflating foam sleeping pad because it's reasonably comfortable and weighs only 16 ounces.
Other construction types offer more performance. The Nemo Astro Insulated is our top rated all-purpose pad and offer the best value for those who want one pad for both backpacking and car camping. If saving weight is your top priority go for either the Therm-a-Rest NeoAir XLite - Women's (11oz) or Therm-a-Rest NeoAir XTherm (warmer, more durable, and 15 oz). These latter two options are better for multi-day trips than the Peak Oyl Mtn.
