Designed to meet the unique needs of female physiology, our Women’s Ultra Light S.I. Mat provides increased warmth and sleeping comfort in a small and light package. The foam used in our Women’s specific Delta Core-V graduated pattern uses a mix of smaller holes and solid foam under core body zones for extra warmth where women often feel the cold most. Featuring a women’s specific shape that is wider at the hip and narrower at the shoulder, the anti-slip print on the top and base of the mat holds it in place when camping on sloping ground is unavoidable. Made from lightweight 30D polyester with extrusion laminated TPU, it packs down incredibly small for minimalist adventures.

FEATURES

  • Women’s specific Delta Core profile developed to create warmer core body zones
  • Wider at the hip and narrower at the shoulder
  • Multi-function, high flow-rate valve
  • Larger vertical Delta Cores in non-body contact areas reduce the mat’s weight and bulk
  • Anti-slip print on top and base keeps it in place
  • Lightweight 30D polyester with extrusion laminated TPU used on top and base
  • Pillow Lock attaches your Aeros pillow to your mat, holding it in place for a slip-free sleep

My puppy loves it
Color: Teething Stick
It's cute and a good size for my chihuahua puppy. It seems to be slightly tearing at the seam in the middle, but hopefully it will hold up.

LOVE this tough toy! My teething puppy is still enjoying it!
Color: Hedgehog
LOVE the hedgehog! Very tough! My dachshund has not been able to chew off any of the 'nubs', and does she try! lol The only thing is, the first thing she did was chew off the nose, but I discarded it and watched her closely to make sure she didn't chew off any more, and no, its still being chewed on. Wish I could find more toys like this one!!

still searching for a truly indestructible dog chew toy
Color: Hedgehog
My smallish dog (15 lb Boston terrier) got this chewed up within a half an hour. I didn't notice right away that he was also eating the parts he chewed off. Didn't last a day. Otherwise, quick shipping for a cute toy.

Good size for my pug!
Color: Dentachew 3 Pk
I love how it’s a good size for my pug it is easy for her to play around with. I had stuffed animals for her to play around with but it looked so silly to watch her play with something that is 10 times as big as her 😂. I had to buy her these toys and she seemed so happy when she first got them. It was so funny and interesting that she had to chew all three toys and decide which one she liked. At first she decided to play with the rope toy and she liked the rope toy, then she got curious with the rubber toys. She has decided that the rubber toys are her favorite and I’ve tried to engage with playing with her with the rope toy. She gets more interactive with the rubber toys! She also looked so relieved while chewing them so that’s a plus!

Good for Teething puppies
Color: Teething Stick
After getting my fingers chewed and bitten by my new foster - 8 week old Yorkie , I was desperate to find good teething toys. Fortunately this one arrived quickly. Turned out to be very good for teething puppies! Charlie loves this cooling stick. Once it’s frozen, the cold really seems to soothe his sore gums. The icy part doesn’t stay frozen for long, but it works so well that I bought a second one to keep ready in the freezer while he’s working on the first. Even after it warmed up, he still enjoyed chewing on the soft stuffed part and the tentacles. The product card says not to use it as a chew toy, so supervision is a must, but it held up just fine so far. Overall, this has been a big help during the teething phase — short-lived when frozen, but very effective while it lasts! And worth every penny to save my fingers from being a chew toy.
