such an awesome product swig rigs are the way to go. I now own 2 of the swig 63 rigs now both on 1.5l Nalgenes and looking at getting 2 more in the future for my smaller 1L nalgenes.
I've never had any problems with the inside straws falling off or leaks truely an amazing product and enough videos on the websites as guides it is literally an idiot proof product.
Can't wait to see what thw company comes out with next.
Living in the UK I have to import when I buy but it's totally worth it when ypu realise it's a buy once product unless ypu have the same bug as me and need one swig rig cap for each bottle I own.
Definitely worth the upgrade, particularly in warmer environments.
The light is bright enough for trail riding and works great! Totally meets my needs and glad I made the purchase
