Thermarest Alpacka Pump Adapter (Classic Valve)

This great little adapter lets you use your Alpacka Raft Pack-A-Pump or Alpacka Raft Inflation Sack to fill up your Thermarest Sleeping Pad (Classic Valve Only) when you get to camp. 

The Inflation Sack is the real winner here, as it moves a ton of air and let's you fill your pad in only a few bag-fulls. 

Be careful using this adapter with the Pack-A-Pump, as it could theoretically blow apart your sleeping bag if you over-inflate it. 

Material Note:

• PETG is a stronger and more resilient material. Choose this for the ultimate longevity out of this part. Unfortunately it is only available in Black and White. 
• PLA is a weaker material, but will probably last decently long as well. There are more colors available in PLA.
